　　Iii. Receiving and handling applications for government information disclosure

　　Four, the government information disclosure of administrative reconsideration and administrative litigation.

　　V. Main Problems and Improvements

　　1. In terms of policy interpretation, the interpretation of major policy measures still needs to be strengthened, and the interpretation of professional policies is not visual and popular enough. In the next step, we will enrich the forms of policy interpretation, use concise questions and answers on policies, ask about politics on the Internet, and introduce policies into the community, and use charts and diagrams, audio and video, cartoons and other forms that people like to show.

　　2. In terms of decision-making, the next step will be to establish and improve the pre-disclosure system for major decisions. For major decisions that involve the vital interests of the public and need to be widely known by the society, all relevant units will be urged to announce the draft decisions and decision-making basis to the public before making decisions, and listen to public opinions extensively.

　　Vi. Other matters that need to be reported

　　The website of the People’s Government of Tongzhou District in Beijing is http://www.bjtzh.gov.cn. For more information about the government, please visit the website.

　　Convene a conference on the compilation of flora and fauna in China
　　　　China Fauna and Flora is a national basic scientific data, which comprehensively and systematically summarizes the species, distribution, systematic relationship and economic significance of China’s organisms, and provides basic data for the exploration and utilization of national biological resources and related construction, scientific research and teaching work. The national flora and fauna is one of the symbols reflecting the development level of a country’s biological science. Many countries in the world attach great importance to compiling national flora and fauna. In 1959 and 1963, China Academy of Sciences established the Editorial Committee of Flora of China and Fauna of China, and organized relevant biologists inside and outside the Academy to compile the Fauna and Flora of China.
　　With the approval of the State Council, the conference on the compilation of flora and fauna of China hosted by China Academy of Sciences was held in Guangzhou from February 29th to March 7th, 1973. Attending the meeting were 181 representatives from relevant scientific research units, universities, science and technology management departments, cultural, educational and health units in 26 provinces, municipalities and autonomous regions. This meeting discussed some principles of compiling flora and fauna, such as: compiling flora and fauna should be improved on the basis of popularization, and it should be strict and scientific, reflecting the level of China; We should not only ensure quality, but also strive for speed, so as not to affect quality because of greed and quickness, and also avoid delaying time because of unrealistic requirements for quality; In the deployment of work, it is necessary to prioritize, and concentrate as much as possible on the flora and fauna that are closely related to the economy, important in the scientific sense and rich in information, and prepare them first to ensure completion; Correctly handle the relationship between the compilation of China flora and fauna and local flora and fauna, and pay attention to giving full play to the enthusiasm of the central and local governments.
　　At the meeting, the editorial boards of Flora of China and Fauna of China were adjusted and enriched, and the editorial board of Spore Flora of China was established. These three editorial boards are led by the Institute of Botany, the Institute of Zoology and the Institute of Microbiology of China Academy of Sciences respectively. The meeting drew up the compilation plans (drafts) of Fauna of China, Flora of China and Flora of Spore of China. These drafts will be implemented as formal plans after obtaining the consent of relevant competent departments and units undertaking tasks.
　　Reprints of China Science and Science Bulletin
　　China Science and Science Bulletin, comprehensive natural science journals sponsored by China Academy of Sciences, were suspended for seven years after the Cultural Revolution. At the strong demand of the majority of scientific workers, it was reissued in February this year and publicly issued at home and abroad.
　　The editorial board appointed by the Academy of Sciences is responsible for editing the reissue of China Science, which is divided into Chinese and foreign languages. It publishes papers that study natural science theories and summarize production struggles and scientific experiments; Papers from different schools of natural science and articles on major scientific and technological achievements. On February 17th, the Academy of Sciences informed the Science Bulletin that there would be no editorial board, and the editorial board of China Science would be responsible for it. It publishes scientific and technological research achievements, academic trends and some critical articles. In the historical environment at that time, the two publications had to compile and distribute some political articles. The first issue of Science Bulletin was published in July.
　　By September this year, there were more than 30 kinds of journals and intermediate academic journals that stopped publishing in 1966.
　　Establishment of theoretical system of bulk fluidization in chemical metallurgy
　　The theoretical system of bulk fluidization in chemical metallurgy was put forward by Guo Musun, a researcher at the Institute of Chemical Metallurgy, Chinese Academy of Sciences, in his article "Bulk Fluidization in Chemical Metallurgy". This paper was published in the third issue of China Science in 1973, and was read out at the first Iranian chemical engineering conference in May of that year.
　　Fluidization refers to the state that solid particles are suspended under the action of fluid, and the particle group at this time is similar to fluid. Generally speaking, fluidization can be divided into two categories: scattered fluidization and aggregated fluidization. The granular materials in the fluidized bed are evenly dispersed and smoothly fluidized, which is called loose fluidization. Usually, liquid-solid systems form bulk fluidization. Fluidization technology has been used in industry for decades and is a mature technology. However, due to the complexity of the movement law of particles and fluids, the complex factors of chemical reaction and reactor, and the fluidization technology itself involves many disciplines such as multiphase fluid mechanics, chemical reaction engineering, particle science and statistics, etc. Although scholars at home and abroad have done a lot of theoretical research work and accumulated a lot, there is no completely unified theory to describe it, and there is also a lack of methods for reactor scale-up and design, so the design scale-up of industrial fluidized reactors is still based on experience.
　　Guo Musun’s paper points out the characteristics of a completely uniform ideal fluidization system and explains some concise parameter relations in this ideal fluidization. This theory can be used as a useful tool to analyze many practical fluidization engineering problems, clarify the relationship and operation mechanism of various operating variables, explain some practical phenomena, and have enlightenment significance for the design method and development direction of fluidization technology. On the basis of summarizing predecessors’ work, Guo Musun grasped the characteristics of uniform and stable liquid-solid bulk fluidization, put forward the theory of bulk fluidization, and formed an independent and complete theoretical system, which was a breakthrough in the basic theoretical research of fluidization and applied it in practice. This research achievement won the second prize of the National Natural Science Award in 1982.
　　The science and technology group of the State Council Science and Education Group was merged into the Academy of Sciences.
　　On August 11th, the State Council Science and Education Group and China Academy of Sciences issued a joint notice to all localities and departments, and China Academy of Sciences was responsible for organizing the formulation of long-term scientific and technological plans and annual plans for civil use, the allocation of three scientific and technological expenses and corresponding materials, and the coordination and inspection of plans. On August 24th, the office meeting of China Academy of Sciences decided that the agency responsible for this work should be the Science and Technology Office of China Academy of Sciences.
　　After the merger of the State Science and Technology Commission and China Academy of Sciences on July 1, 1970, China Academy of Sciences set up the first business group (also known as business group 1) to take charge of the work of the former State Science and Technology Commission. After the National Conference on Education in July 1971, the State Council decided to set up a science and education group to take charge of the work of the former State Science and Technology Commission and the Ministry of Education. Li Siguang is the team leader, and Liu Xiyao and Chi Qun are the deputy team leaders. After Li Siguang’s death in 1971, Liu Xiyao took over as the leader of the State Council Science and Education Group.
　　In July and August, 1972, the Science and Education Group and the Academy of Sciences agreed that the national science and technology management work should be centralized by the Science and Education Group of the State Council, and the business personnel of the comprehensive plan and scientific experiment dynamic group of the first business group of the Academy of Sciences were transferred to the Science and Education Group to form a science and technology group. In May, 1973, the Science and Education Group asked Premier the State Council and Premier Zhou Enlai for instructions, and thought that the China Academy of Sciences, which is in charge of scientific and technological work in various departments and localities of the national economy, has great limitations, so it is difficult to do a good job and it is easy to attend to one thing and lose sight of another. It is suggested that the scientific and technological work in the production and construction of various departments and localities of the national economy should be planned and coordinated by the State Planning Commission. Medical and health science and technology work is still centralized by the Ministry of Health. The report also puts forward specific suggestions on the tasks and responsibilities of the State Council Science and Education Group in science and technology. The State Council did not reply to the report. However, after the establishment of the Science and Education Group, Premier Zhou Enlai repeatedly suggested that the Science and Education Group should not have more staff, and the scientific and technological work should rely on the China Academy of Sciences.
　　In August, 1973, the members of the Science and Technology Group of the State Council Science and Education Group withdrew to China Academy of Sciences, and continued to be responsible for the management of national science and technology work in the name of the Office of Science and Technology. This situation was maintained until the reconstruction of the State Science and Technology Commission.
　　Complete the determination of 1.8 angstrom pig insulin crystal structure.
　　In August, the Beijing insulin crystal structure research group, composed of the Institute of Physics of Chinese Academy of Sciences, the Institute of Biophysics and relevant personnel from Peking University, completed the determination of the crystal structure of 1.8 angstrom pig insulin.
　　The determination of insulin crystal structure began in June 1967. Insulin is a biological hormone, and it is the smallest protein. The biological activity of protein is not only related to its chemical structure (generally called primary structure), but also closely related to its spatial structure (generally called three-dimensional structure). The purpose of determining the crystal structure of insulin is to determine the relative position and relationship of each atom of insulin molecule in three-dimensional space, which can provide an important basis for further studying the mechanism of its biological activity and exploring the relationship between its structure and function. The work of the research group includes: the cultivation of insulin single crystal, the preparation of heavy atom derivatives, the collection and processing of X- ray diffraction data, the calculation of phase angle of structural factors, the analysis and interpretation of electron density diagram, the establishment of structural model and other steps. On the basis of measuring the resolution of 4 angstrom and 2.5 angstrom in September 1970 and January 1971, the measurement of the resolution of 1.8 angstrom was completed in August this year. The research on the determination of the crystal structure of porcine insulin won the second prize of the National Natural Science in 1982.
　　Like the synthetic yeast alanine transfer ribonucleic acid, the research on the determination of the crystal structure of porcine insulin was successful in the Cultural Revolution, thanks to the support of Vice Premier Nie Rongzhen.
　　The initial-boundary value difference method and the mathematical basis of flow calculation are put forward
　　Since 1960, the Computational Mathematics Laboratory has been undertaking the research on aerodynamic and aerothermal numerical methods of missiles and satellites, and has provided a large amount of data for the entrusting department. By the mid-1960s, Zhu Youlan and others put forward a set of systematic and high-precision calculation methods based on the theory of separation singularity and characteristics-the difference method for initial-boundary value problems and inviscid flow, and in 1973 gave the mathematical basis of the methods.
　　This method has high accuracy. At that time, because of the equipment embargo, it was impossible to import large-capacity and ultra-high-speed computers, and the aerodynamic force and flow field of aircraft could be well calculated by using the computer developed by China. Not only the shape of the blunt cone can be accurately calculated, but also the shape and flow field of the blunt cone-column-skirt combination can be accurately calculated. It has provided the results of flow field data for the first recoverable satellite in China, and contributed to the safe and accurate return of the satellite to the ground. Users praised this method for giving a set of numerical methods for initial-boundary value problems of hyperbolic equations, which achieved high accuracy and were more perfect, more careful and more unique than similar works abroad. In 1982, this achievement won the third prize of the National Natural Science Award.
　　Model 655 computer was successfully trial-produced.
　　In 1964, IBM Corporation of the United States announced the successful development of the IBM360 integrated circuit computer system, which opened the curtain of the third generation computer, and this trend attracted the attention of computer technology experts in China. The following year, East China Computing Institute began to develop 655 integrated circuit computers. The required integrated circuits are trial-produced by Shanghai Metallurgical Institute and relevant semiconductor factories in Shanghai. The machine was successfully trial-produced in 1973, with an operation speed of 1 million times per second and a memory capacity of 128,000 words. At that time, it was the fastest integrated circuit computer with the largest memory capacity in China.
　　This computer, together with Model 013 integrated circuit computer with a computing speed of 2 million times per second, which was developed in 1976, jointly undertook a large number of computing tasks in the development of atomic bombs, missiles and artificial satellites after the 109 C computer.

　　Song Joong Ki meets fans. On May 14th, the "2016 Song Joong Ki Asia Tour Fans Meeting" was held at the National Olympic Center Gymnasium. Korean artist Song Joong Ki interacted with fans at the meeting, causing fans to scream. Song Joong Ki will also go to Wuhan, Guangzhou, Shenzhen, Shanghai, Hong Kong, Chengdu and Taipei to complete the fan meeting in eight cities in Greater China.

　　I finally waited for you, but I didn’t give up. On May 14th, Song Joong Ki held the first meeting of fans on the Asian Tour in Beijing. Nearly one gymnasium with a capacity of 10,000 people was packed. Song Joong Ki, the "national husband", appeared in the screams of fans with a white shirt and black trousers, and appeared on the lifting platform, just like the prince in every girl’s heart.

On October 7th, the results of the 2023 hybrid vehicle extreme challenge competition were announced. The Roewe D7 DMH, a "super hybrid cloud car", won the first place in the medium-sized and large-sized car group with its excellent comprehensive performance. At the same time, in the fuel consumption test, Roewe D7 DMH won the championship of the whole vehicle with the ultra-low fuel consumption of 4.61L/100km, which proved with strength that "the strongest is in China, and the strongest in China is in Roewe".

Co-sponsored by China Automotive Information Technology (Tianjin) Co., Ltd. and China Automotive Research Center (Kunming) Co., Ltd., this challenge is the first professional competition for hybrid vehicles in China, covering several popular hybrid vehicles in the market. The test items include pure battery life, fuel consumption due to power loss, comprehensive energy consumption, extreme energy consumption, NVH, power performance, etc., which can comprehensively evaluate the comprehensive strength of hybrid vehicles.

Relying on technology brands, a forward-looking new energy source of SAIC, Roewe launched the first plug-in hybrid car "Roewe e550" in China in 2013. The first generation of EDU hybrid technology independently developed by SAIC won the second prize of the National Science and Technology Progress Award in 2017, which was not only the only automobile project among the award-winning projects in that year, but also the first time that new energy technology won the national science and technology award. After ten years of sharpening, after continuous technical investment and innovation, Roewe D7 DMH equipped with a new generation of DMH dual-motor hybrid technology will be launched this year, providing users with more stable and efficient hybrid new choices.

Super hybrid: ultra-low fuel consumption and long battery life

The long-distance test of this challenge is set in the Yunnan-Guizhou Plateau with relatively complex terrain changes and certain challenges in altitude, which can simulate the travel scene of consumers more realistically. Thanks to the technical advantages of the dedicated high-efficiency long-life battery, Roewe D7 DMH won the first place in the actual battery life measurement with a battery life of 142km, which was significantly better than that of the same group. The comprehensive cruising range is as high as 1400KM, which is enough for users to travel without worry and run further.

In addition to the long battery life, Roewe D7 DMH’s performance in power and fuel consumption is also remarkable. D7 DMH adopts the industry’s first PICU power domain controller with five-in-one engine, gearbox, hybrid mode, thermal management and air conditioning management. One of its advantages lies in its extremely fast dynamic response, which only takes 0.26S s.. In the 100-kilometer acceleration measurement, D7 DMH only takes 8.3S seconds to accelerate at zero hundred kilometers, and the power is very easy to obtain.

According to the actual measurement, the fuel consumption of Roewe D7 DMH is only 4.61L per 100 kilometers, which is the lowest among all the participating models. The ultra-low fuel consumption is attributed to the thermal efficiency of the 1.5L hybrid engine exceeding 43% and the ultra-low loss brought by 18 world-leading low-friction technologies. Under the condition of ensuring sufficient power output, the fuel consumption can still be maintained at a relatively low level. In addition, D7 DMH adopts dual motors in series, providing five driving modes. Users can choose the driving mode independently, and run in an optimal state under various working conditions. The power is strong and the fuel consumption is time-saving, which improves the overall efficiency and reduces the vehicle cost.

Yunsu intelligent cockpit: silky smooth, spacious and quiet.

The challenge test track runs across the Yunnan-Guizhou Plateau from east to west, with the characteristics of steep slope, sharp bend and slippery road, which tests the dynamic driving and control performance of vehicles. Roewe D7 DMH adopts multi-link rear suspension, and matches with international first-class chassis suppliers such as SKF, Weibak and GF, as well as the systematic and ingenious adjustment of the chassis of SAIC Innovation and Research Institute, thus ensuring excellent handling performance and precise and delicate steering. In the test, in the face of all kinds of road conditions, D7 DMH greatly reduces the front and rear force from the road surface, and at the same time, with the support of CST, the brakes do not nod. With the aluminum alloy wheel bracket, the isolation effect in the car is better and the overall dynamic comfort is better.

In terms of driving experience, Roewe D7 DMH’s carefully polished intelligent cockpit will bring users the comfort of staying in the cloud. With the longest body of its class of 4890mm and an ultra-long wheelbase of 2810mm, D7 DMH can realize flexible seat combinations, meet the needs of multiple scenes, and create a necessary happy space for mid-to high-end cars. The zero-gravity cloud somatosensory seat with high-grade suede is widely used, and the backrest is made of 9 layers of materials. It comes standard with soft foam with the first thickness of the same class, and adopts U-shaped embracing design to fit the waist curve of Chinese people, so that the waist and buttocks can be effectively wrapped and elastically supported. The length of the front and rear seat cushions has reached the leapfrog level, providing better support for the legs, sedentary and not tired, and the overall main "cloud feeling" general comfort experience. In addition, the collaborative mute technology actively suppresses noise from the noise source, and quietness adds more comfort to the comfortable space.

Roewe D7 DMH is also equipped with a brand-new Zebra Intelligent Driving Machine System, which not only supports multi-meaning in one word, but also allows users to express 10 intentions in one sentence. Moreover, cars and mobile phones can flow seamlessly, and information such as countdown to traffic lights and tidal lane can be displayed dynamically in real time, which is practical, convenient and worry-free, while meeting the multiple needs of users and creating rich driving pleasure.

Roewe D family was born to meet the whole scene consumption demand in the new energy technology era, and it is also a brand-new image of Roewe in the new energy technology era. As the first model of D family series, Roewe D7 is the epitome of SAIC’s profound knowledge and innovative ability of new energy technology. This time, the Roewe D7 DMH won the first prize in the extreme challenge of hybrid cars with the advantages of long battery life, ultra-low fuel consumption, excellent driving control and comfortable driving experience, showing the quality and charm of super hybrid cloud-feeling cars, and further consolidating Roewe’s position as a pioneer in the field of hybrid technology.

Once, a shocking news was like a stone thrown into a quiet pond, causing ripples. Singer Hua Chenyu announced an incredible fact, that is, his relationship with singer Joe superstar suddenly added another dimension: his daughter.

How to understand this puzzling news? How did two music giants who had nothing to do with each other get together and give birth to a child? All this is confusing, and only by digging deep can we uncover the veil of truth.

Some people say that life is like a movie, and you never know what will happen in the next scene.

For Hua Chenyu and Diamond, this turning point seems to be a miracle in their lives.

As a rising star in music, Hua Chenyu stands out among many musicians with his unique musical style. However, his life experience is far more complicated than imagined. His father Hua Fuxiong is a billionaire mining tycoon. Rich as jade, he is the son of a noble family.

Diamond is a shining star in the music industry. With his outstanding musical talent and strength, he once held the pillar position in the entertainment circle. She has always regarded music as a part of her life, however, her life seems to have changed irreversibly at some point.

Then, just when everything seemed calm, Hua Chenyu’s social media released an amazing message-"We have a baby". This sentence is like a bomb, which caused a great sensation.

However, this news is not a simple good news, but the beginning of a mystery. Because before, the relationship between Hua Chenyu and Diamond hardly involved the public eye. There is no gossip between them, as if they are people from two different worlds.

However, with the hot discussion of public opinion, some details began to surface.

It turned out that Wan Li, not far from Diamond, came to the United States to give birth to this child. Hua Chenyu seems to know nothing about this process, and he didn’t know this amazing fact until the child was born.

This led to widespread speculation that Diamond did this to bind Hua Chenyu and force them to get married. However, this single-handed action reveals that she seems to regard Hua Chenyu as a superior tool.

However, reality is often more complicated than it seems. DNA testing finally confirmed the blood relationship between her daughter and Hua Chenyu, and Hua Chenyu had to reluctantly admit this fact.

But he publicly announced that the two would not get married and would only raise children together.

It is said that Hua Chenyu privately provided material compensation, gave Diamond a luxury villa and provided generous living expenses every month. Thus, Hua Chenyu didn’t really accept this sudden daughter. He just regarded it as an unexpected burden and chose to solve it with money.

Emotionally, he seems to be frustrated with Diamond. Diamond’s plan finally failed. She failed to marry into a rich family, but her real motives were exposed and her reputation was damaged.

Nowadays, Diamond is facing pressure from all sides, and the cold eyes of the entertainment circle are full of her life. However, as a mother, she must face the burden of raising children alone.

Perhaps, simply looking at this incident from the perspective of "trading power and money" will make us lose our deep understanding of this matter. Life is full of unpredictability, and interpersonal relationships are not black and white. Perhaps, Diamond’s choice contains sincere feelings, not just cold calculation.

After all, the story of two loving hearts can never be ignored. We shouldn’t jump to conclusions and label them unfair.

According to relevant data, by the end of 2022, the number of electric two-wheeled vehicles in China has reached 400 million. What is the concept of this number? If we just look at the numbers, it is probably that one in every three people in China owns an electric two-wheeled vehicle on average. China is the largest in the world.Electric two-wheeled vehicle marketSince the birth of the first electric vehicle in 1985, the whole domestic market has been expanding rapidly, and it has grown against the trend in the past few years, from the annual sales of 30.5 million vehicles in 2017 to 60.07 million vehicles in 2022. At present, the market is already in a very fierce competitive state. For many brands, whoever can take the lead in innovation in technology and products will gain an advantage in the competition. Seeking a longer-term development, and No.9 is empowering products with innovative technology, bringing intelligent products to many users and gaining a place in the market competition for itself.

Electric vehicles enter the era of intelligent machines.

In 1995, the first light electric vehicle with column brushless DC motor was developed in Tsinghua University, and China’s two-wheeled electric vehicle industry started from then on and entered a new development period.

Two-wheeled electric vehicles have been welcomed by many consumers because of their convenient travel, high cost performance and simple operation, and have become the first choice for many urban white-collar workers to commute in short distances.

Since 2000, with the breakthrough of key technologies and the improvement of vehicle performance, China’s electric vehicle industry has entered a preliminary scale stage. In 2004, the Road Traffic Safety Law of the People’s Republic of China identified electric bicycles as non-motor vehicle legal models, and electric bicycles were more widely used, and the industry entered a stage of rapid development. Since 2014, due to the adjustment of industrial structure and other factors, the development speed of the two-wheeled electric vehicle industry has slowed down and entered a mature stage. The scale of the industry has remained around 70 billion yuan, and the production and sales volume have declined for the first time at this stage.

In 2019, with the release of "Technical Specification for Electric Bicycle Safety", the whole two-wheeled electric vehicle industry began to enter the development stage of the new national standard, and the demand for redemption in the electric vehicle market continued to rise, not only the production and sales volume increased, but also the market scale continued to expand, and the fierce competition in the industry gradually entered the incandescent stage. Many brands began to enhance their own product marketing efforts in order to gain greater market share, and the price of electric two-wheeled vehicles in China also ushered in a downward trend.

In the past few years, the sales of electric two-wheeled vehicles in China have been in the low-priced area, and the competition trend has become increasingly fierce. With the arrival of the new period, the electric two-wheeled vehicle market has begun to enter new changes, and new forces are gradually sprouting and occupying a new world in the market, including No.9.

Founded in 2012, Company No.9 mainly produced electric balance cars at first, and then gradually added electric scooters, electric two-wheelers and service robots. The company is committed to providing smart mobile solutions in various fields with intelligent innovation as its gene. Up to now, No.9 has sold more than 4 million electric balance cars and more than 12 million electric scooters. In addition, No.9 also successfully launched an intelligent electric two-wheeled vehicle, and achieved domestic shipments of more than 1.5 million units in the shortest time.

With the landing of the new national standard, Company No.9 has successively launched a number of new products, including E series of electric motorcycles, C series and B series of electric bicycles. These products are equipped with RideyGo stop-and-go system and lithium battery intelligent BMS 6. 0 technology independently developed by No.9, as well as functions such as GPS, Beidou and base station triple positioning. The advantages of these technologies and products have brought No.9.Electric vehicle salesWith the rapid growth, the sales volume in 2012 has reached 420,000 units, a year-on-year increase of nearly 300%. In the first half of 2022, the revenue of No.9 electric two-wheeled vehicle reached 930 million yuan, up 81% year-on-year, and its market share ranked first in China. According to the industry report, the market share of No.9 in the middle and high-end price of more than 5,000 yuan and more than 7,000 yuan will continue to lead.

The intelligentization of electric vehicles is entering the 2. 0 era. Company 9 will continue to innovate and provide users with more convenient, intelligent and effective travel solutions.

hard technology

Company No.9 held a new product launch conference in 2023 on May 10th, and launched a variety of intelligent new products, including No.9 electric E300P, Xiao V and Xiao Q, No.9 electric scooter E2 gardenia white new color, Segway AT5 all-terrain vehicle, Segway energy storage power Cube, etc., and displayed No.9 electric scooter F2 series and No.9 children’s electric scooter C2 Pro and other products.

Among them, the No.9 electric E300P is the flagship intelligent electric motorcycle in the future, and it is the main high-performance product. For the first time, it realized the expansion of three batteries, the peak power reached 20kW, and the acceleration time of 0-100km/h was 7. 9 seconds, which not only had strong performance, but also had a long battery life. In addition, the brand-new Xiao Q and Xiao V have created a personalized and portable travel experience for female users and the whole family.

It is worth mentioning that on December 17, 2019, No.9 entered the two-wheeled electric vehicle market for the first time, and released No.9 electric E series and C series, among which E200P model was launched in 2022. The E300P released this time follows the design gene of E-series tension aesthetics, and on this basis, it strengthens the offensive visual experience, and the overall design is more muscular and powerful.

What’s more gratifying is that through in-depth research and development of innovative technology, No.9 is equipped with HIAS system for intelligent electric two-wheeled vehicles for the first time in China. This system has brought a more stable and comfortable driving experience to No.9 electric vehicle after being applied to intelligent electric two-wheeled vehicles.

It is reported that HIAS system is a kind of inclination adjustment system suitable for motorcycles. When the motorcycle turns, the body will also be inclined, and when bending at high speed, the dumping will be particularly obvious. At this time, the paving range of the light will be seriously deformed, and the vehicle is prone to short-sightedness or dead angle. By using the attitude sensor, HIAS system can calculate and correct the paving range of light, and adjust it at 40 degrees on the left and right sides respectively. This effectively solves the problem of insufficient lighting distance when the vehicle is bent.

True intelligence

In the intelligent 2.0 era of electric two-wheelers, the software will drive the hardware to improve the overall experience of electric two-wheelers.

At the press conference, the first product released by No.9 Electric is the new Q series Xiao Q, which focuses on the personalized design of youth and fashion, especially suitable for female riders.

The No.9 electric Q is equipped with a variety of intelligent functions, including triple positioning anti-theft and keyless unlocking functions, which makes female riders feel more at ease and free to travel.

In addition, Xiao Q also adopts the advanced RideyLONG long endurance system, which can reach the cruising range of 95km, so that users don’t have to charge frequently and travel more conveniently.

Xiao Q’s safety performance is also excellent. It is equipped with anti-bacterial handlebars and TCS traction control system to ensure the safety and stability of riding on low adhesion roads such as wet roads.

The flagship product E300P is equipped with RideyFUN! Intelligent system, with a 7-inch TFT full-fit screen with a peak brightness of 1000 nits, supports functions such as music, navigation and call. E300P has designed ergonomic combination switch, customized ATUO case, and gamepad-level feedback, which makes users’ riding experience richer.

Intelligent tidal head

In our stereotype, electric two-wheeled vehicles seem to be a relatively traditional industry, and users’ demand for electric two-wheeled vehicles seems to remain at the level of high cost performance and meeting travel needs. However, in fact, with the progress of science and technology and the continuous development of society, the consumer market has also undergone new changes and upgrades, and consumers have new requirements for intelligent travel.

According to the report of iResearch, battery life and riding comfort are still the main considerations when users buy electric two-wheeled vehicles, but more than 20% of users will also pursue intelligent functions.

With the development of technology, the concept of intelligence is being more widely recognized and applied, and the demand of users for electric two-wheeled vehicles is also changing from cost-effective to paying more attention to specific experience value and the intelligence of operating rods.

In such a competitive market environment, technology-driven product experience becomes more and more important. No.9 Electric took the lead in bringing electric two-wheeled vehicles into the era of intelligent 2. 0, focusing on closed-loop user demand and product innovation.

This intelligent concept enabled No.9 Company to significantly improve its sales performance during 2022- 2023, reaching the delivery targets of 1 million and 1.5 million vehicles, and becoming one of the fastest enterprises in the industry to achieve this goal.

The sales of No.9 electric vehicle are ahead of the domestic high-end electric two-wheeled vehicle market with a price of more than 5,000 yuan, and it holds 51% of the market share of high-end electric two-wheeled vehicles with a price of more than 7,000 yuan.

This is only the beginning of the intelligentization of electric two-wheeled vehicles, and there is still more room for development in the future. No.9 will continue to stand at the forefront of intelligence, providing users with more reliable and intelligent travel solutions.

　　May 27, 2001 news: Since September 28 last year, the Palestinian-Israeli conflict has escalated step by step, and Israel and Arab countries are sliding to the brink of war.

　　In retaliation for a suicide bombing by an "Hamas" in the central city of Netanya, on the afternoon of May 18th, Israeli F-16 fighter jets and helicopter gunships were simultaneously dispatched to carry out fierce air strikes on Palestinian targets in the West Bank and the Gaza, killing 11 Palestinians and injuring more than 100 others. Over the past few months, Israeli air force helicopter gunships have fired missiles at Gaza many times, but this time the situation is completely different, because the power of F-16 fighter jets is incomparable to Apache helicopter gunships.

　　Sharon has always been called the "War Horse", and his consistent tough attitude makes people worry that if this "War Horse" gets out of control one day, it will bring new disasters to the Middle East.

　　Arab countries will never back down.

　　On the 19th, the Follow-up Committee of the Arab Summit held an emergency meeting at the level of foreign ministers in Cairo. Foreign ministers and representatives from 10 Arab countries including Egypt, Jordan and Syria attended the meeting. The statement adopted at this meeting stated that the Arab countries will spare no effort to support the struggle of the Palestinian people.

　　In the face of Israeli aggression, Pakistan indicated that it would continue to fight against Israeli aggression. In his speeches on different occasions, Arafat has repeatedly said that Israel is trying to conquer the Palestinian people by force, but the Palestinian people will never give in, and Palestine will definitely establish its own independent country and plant the national flag in East Jerusalem.

　　Syria and Lebanon are ready

　　Recently, the Israeli army has frequently dispatched helicopter gunships to attack the targets of Hezbollah guerrillas in southern Lebanon, and bombed the Syrian radar station in the Bekaa Valley. Israeli military aircraft have repeatedly invaded Lebanese airspace, including the capital Beirut, and carried out threatening flights. Israeli Defense Minister Ben eliezer recently threatened that if Hezbollah guerrillas did not stop attacking Israel, the Israeli army would attack Syria, its "responsible party", instead of Hezbollah’s target.

　　After learning of the Israeli threat, Bashar, who was visiting Egypt, immediately decided to return home early and hold a high-level leaders’ meeting to study countermeasures. Bashar also called Lebanese President Lahoud on the 17th to discuss the deteriorating situation in the Middle East and coordinate the positions of the two countries. People are worried that if all parties do not exercise restraint, the tension between Lebanon and Israel and Syria and Israel may be further aggravated. The prospect of the situation in the Middle East is unpredictable.

　　The intensified Palestinian-Israeli conflict has aroused widespread concern in the international community. The international community is stepping up its efforts to restore peace in the Middle East. At present, there are two international suggestions on ending the Palestinian-Israeli conflict: one is the Egyptian-Jordanian peace talks plan jointly put forward by Egypt and Jordan, and the other is the Mitchell report submitted by the International Committee on the Palestinian-Israeli Conflict, which puts forward a set of suggestions on ending the Palestinian-Israeli conflict.

　　But a cruel fact is that after nearly eight months of conflict, the mutual trust between Palestinian and Israeli leaders has been completely destroyed, and the opposition and hatred between the people of the two countries are getting deeper and deeper.

　　At the beginning of the Palestinian-Israeli conflict, I’m afraid no one could have thought that the conflict would last so long and develop to such a fierce level. Similarly, people can’t predict what will happen tomorrow in the volatile Middle East.

　　Building the "Belt and Road" is not only a major measure for China to expand its opening up, but also a Chinese plan to solve global development problems, aiming at promoting the common modernization of all countries.

　　Only by carrying forward the spirit of partnership, not forgetting the initial intention of cooperation and moving forward unswervingly can we work together to realize the world modernization of peaceful development, mutually beneficial cooperation and common prosperity.

　　Not long ago, the "One Belt, One Road" Entrepreneur Conference was successfully held, and the grand occasion of business representatives from various countries queuing to sign contracts was widely spread on social media. From entrepreneurs’ conference to three high-level forums on interconnection, digital economy and green development, and then to special forums such as smooth trade, maritime cooperation and clean silk road … … During the third "Belt and Road" international cooperation summit forum, all parties reached a total of 89 multilateral cooperation outcome documents and 369 pragmatic cooperation projects, which injected strong momentum into the modernization of all countries.

　　Modernization is not the "exclusive product" of a few countries, nor is it an "alternative choice". Realizing modernization is the common expectation of people all over the world, and it is also a right. At the opening ceremony of the third "Belt and Road" international cooperation summit forum, the Chairman of the Supreme Leader stressed: "China is willing to deepen ‘ Belt and Road ’ Partnership to promote co-construction ‘ Belt and Road ’ Enter a new stage of high-quality development and make unremitting efforts to realize the modernization of all countries in the world. "

　　Today, China is promoting the construction of a strong country and the great cause of national rejuvenation with Chinese modernization. Chinese-style modernization is a modernization with a huge population, the common prosperity of all people, the coordination of material civilization and spiritual civilization, the harmonious coexistence of man and nature, and the path of peaceful development. The revival pursued by the Chinese nation is carried out under the background of world modernization, which not only aims to realize the prosperity of the country, but also promotes the development and progress of human civilization in this historical process. Facts have fully proved that building the "Belt and Road" is not only a major measure for China to open wider to the outside world, but also a Chinese plan to solve the global development problems, aiming at promoting countries to move towards modernization together.

　　In the past 10 years, the joint construction of the "Belt and Road" has helped many developing countries accelerate the pace of modernization. In Africa, the Inner Mongolia Railway and the Yaji Railway have been opened to traffic, which has become an important channel to promote the in-depth development of East Africa and even the whole African country. In Argentina, the Gauchary photovoltaic power station project was officially connected to the grid to generate electricity, which optimized the local energy structure and helped the local economy to develop sustainably. In Thailand, engineers trained by Luban Workshop are very busy on the production line of Luo Yong Industrial Park in Thailand. In Uzbekistan, the irrigation channel restoration project in Bustam was completed, which solved the irrigation problem of more than 100,000 hectares of farmland … … From a large number of infrastructure construction projects that activate the national development momentum, to many industrial cooperation projects that enhance the national poverty reduction capacity through "giving people the opportunity to fish", and then to the popular support project to enhance the people’s livelihood and well-being, the "Belt and Road" initiative has helped developing countries break the development bottleneck and made China contributions to the common modernization of all countries.

　　Development together is the real development. The Chairman of the Supreme Leader pointed out: "What we are pursuing is not the modernization of China, but we are looking forward to working with other countries, including developing countries, to realize modernization together." Opening a new stage of high-quality joint construction of the "Belt and Road" is of great significance for leading international cooperation and global development under the new situation. Building a three-dimensional interconnected network of the Belt and Road, supporting the construction of an open world economy, carrying out pragmatic cooperation, promoting green development, promoting scientific and technological innovation, supporting people-to-people exchanges, building a clean road, and improving the international cooperation mechanism of the Belt and Road. The eight actions announced by the Chairman of the Supreme Leader that China supports the high-quality construction of the Belt and Road are pragmatic measures to promote the modernization of all countries in the world. Starting from a new historical starting point, building the "Belt and Road" will be more innovative and dynamic, more open and inclusive, and open a new window of opportunity for China and the world. By building the "Belt and Road" with high quality, the development experience of Chinese modernization will continue to provide useful reference for building the country.

　　Realizing modernization is the common cause of all mankind. At present, the changes of the world, the times and the history are unfolding in an unprecedented way, the foreseeable and unpredictable risks in the world have increased significantly, and mankind is facing unprecedented challenges. Bridging differences through dialogue, opposing separatism through unity, promoting development through cooperation, and building the "Belt and Road" are becoming more and more significant, and the prospects are worth looking forward to. Looking to the future, we should adhere to openness and tolerance, transcend the barriers between civilizations through civilized exchanges, and promote tolerance and mutual learning among civilizations; Insist on discussing, building and sharing, and strive to build a global interconnection partnership; Promote common development and constantly explore the "happiness road" that benefits all countries and the world. No matter in prosperity or adversity, no matter whether there are smooth roads or thorns ahead, only by carrying forward the spirit of partnership, not forgetting the initial intention of cooperation and moving forward unswervingly can we work together to realize the world modernization of peaceful development, mutually beneficial cooperation and common prosperity.

　　Carry forward the past, overcome difficulties and forge ahead bravely. We will certainly be able to write a new chapter in the Silk Road era in which countries are mutually beneficial and win-win, people know each other and learn from each other’s civilizations, and create a bright future for all countries to move towards modernization together.

　　(This is the end of this series of comments)

　　The extremely endangered state of the Yangtze finless porpoise has not changed, especially there is a blank area for in-situ conservation of the Yangtze finless porpoise, and there is a risk of "total annihilation" in ex situ conservation. As the most objective and sensitive indicator of the health status of the Yangtze River aquatic ecosystem, the situation of Yangtze finless porpoise population protection is grim.

　　2moonfourJapanese, Yangtze finless porpoise, etc.65This kind of wild animal was officially upgraded from the national second-class protected wild animal to the national first-class one.

　　Behind the protection and upgrading, it shows that the sustainable recovery of the Yangtze finless porpoise population still has a long way to go. The reporters of Outlook Newsweek visited the important habitats of the Yangtze finless porpoise on the spot and interviewed authoritative experts, and learned that the extremely endangered state of the Yangtze finless porpoise has not changed, especially the blank area of in-situ conservation of the Yangtze finless porpoise and ex-situ conservation of species exist.“the whole army is wiped out/overwhelmed/destroyed―meet one’s Waterloo"Risk.

　　“National treasure in water"Return with a smile

　　The Yangtze finless porpoise, the flagship species of the Yangtze River, has frequently appeared in the Yangtze River basin in recent years. They are smiling and playful.“Germination"It won the hearts of the people and also touched the formation of the public.“The Yangtze finless porpoise population is growing rapidly"The impression.

　　“Look, that’s the finless porpoise. Look, it’s out of the water again. It’s still a group."In the cold winter, there is a thin fog in the waters of Zhenjiang Attic and Sanjiangkou in the lower reaches of Gezhouba in the morning, and the Yangtze finless porpoise jumping out of the water from time to time excites photographer Yang He.

　　this year63Yang He, aged 20, grew up by the river and is very familiar with the Yangtze finless porpoise. Yang He remembers,twentyIn the 1970s and 1980s, it was very common for groups of Yangtze finless porpoises to fluctuate in the river.“Because it looks round, most locals call it Jiang pig. It opens its mouth as if it is smiling, so some people call it Jiang pig.‘smiling angel’."

　　In Yanghe’s impression, in the following decades, the Yangtze finless porpoise became less and less frequent, and was even forgotten for a time because it disappeared. until2019yearnineIn May, he accidentally photographed a Yangtze finless porpoise swimming in his riverside photography creation, which made Yang He realize that the Yangtze finless porpoise is back.

　　After that, Yanghe will go to the lower reaches of Gezhouba, Zhenjiang Attic, Sanjiangkou and Yanzhiba every few days.“lie in wait to apprehend a criminal suspect"Yangtze finless porpoise“I shot it at most once.fiveAt the same time, the first finless porpoise surfaced, and the picture of the little finless porpoise clinging to its mother’s fin to feed was also photographed."Yang He said.

　　The smiling return of the Yangtze finless porpoise is the common feeling of the people along the Yangtze River in recent years. After combing government reports and media reports, it is found that Yangtze finless porpoises are found along the main stream of the Yangtze River, including Wuhan, Yichang, Nanjing, Nanchang and Zhenjiang, and in Tongjiang lakes such as Dongting Lake and Poyang Lake, leaving people with scenes of chasing each other and playing against the waves in the water.

　　“In recent years, the number and frequency of the Yangtze finless porpoise reported in various places along the Yangtze River are really exciting."Wang Ding, a researcher at the Institute of Hydrobiology of the Chinese Academy of Sciences and secretary-general of the China National Committee of Man and Biosphere of UNESCO, believes that this is related to“Grasp great protection together."The atmosphere is getting stronger and stronger.

　　Wang Ding said that on the one hand, with the continuous promotion of proliferation and release, pollution control and comprehensive fishing ban along the Yangtze River, the living environment of the Yangtze finless porpoise has been significantly improved, making it possible for it to thrive better. At the same time, with the improvement of people’s ecological awareness, more and more people are involved in the protection of the Yangtze finless porpoise. According to incomplete statistics, at present, there are hundreds of Yangtze finless porpoises protection associations and organizations in cities along the Yangtze River. Everyone cares about the information of Yangtze finless porpoises, which further enhances the existence of Yangtze finless porpoises.

　　The critically endangered situation has not changed.

　　A number of experts on Yangtze finless porpoise research said in interviews that due to the recent lack of global ecological scientific investigation on the population quantity and distribution of Yangtze finless porpoise, local sporadic reports are difficult to support the view that the population quantity of Yangtze finless porpoise has been effectively restored or greatly increased.

　　The latest comprehensive investigation and evaluation of the Yangtze finless porpoise was organized and implemented by the Ministry of Agriculture and Rural Affairs.“2017Investigation on ecological science of Yangtze finless porpoise in". Through Yichang to Shanghai1669Visual inspection and passive acoustic inspection of the main stream of the Yangtze River, Dongting Lake and Poyang Lake, it is estimated that the number of Yangtze finless porpoises is about1012Head.

　　In response to the results of this investigation, Yu Kangzhen, Vice Minister of Agriculture and Rural Affairs2018In 2000, it was said that the trend of the population decline of the Yangtze finless porpoise has been curbed, but its extremely endangered situation has not changed and remains grim.

　　It is understood that in-situ protection, ex situ protection and artificial breeding protection are the three major strategies to rescue the Yangtze finless porpoise. Among them, in-situ protection focuses on taking measures to create a good living space for the wild reproduction of Yangtze finless porpoises; Artificial breeding mainly provides theoretical and technical support for the protection of finless porpoises through scientific research; Ex situ conservation is to artificially move the Yangtze finless porpoise to an area more suitable for its growth and help the Yangtze finless porpoise achieve population expansion.

　　In other words, ex situ conservation is“Preserve species"It is also the most direct and effective measure to save the Yangtze finless porpoise.

　　Located in Shishou, Hubei Province, Hubei Yangtze River Swan Island Baiji Dolphin National Nature Reserve is one of the earliest protected areas for ex situ conservation of Yangtze finless porpoise. Located here“knot in one’s stomach―pent-up feelings of sadness"The Jingjiang section of the Yangtze River is rich in bait and superior in ecological environment, which is suitable for the Yangtze finless porpoise to inhabit.

　　Hu Lianghui, deputy director of the reserve management office, said that this reserve, which was originally set up to protect the baiji, has become a paradise for the protection of the Yangtze finless porpoise due to the functional extinction of the baiji.1990Year,fiveThe first Yangtze finless porpoise was put into the old course of the Yangtze River in Tianezhou. go through30Over the past years, the number of finless porpoises in the old course of the Yangtze River in Swan Island has exceeded.80Head, and every year.sixtill/extremelyeightThe speed of the head increases.

　　According to the calculation of Institute of Hydrobiology, Chinese Academy of Sciences, the ecological environment carrying capacity of Yangtze finless porpoise here is about100Head. At the current growth rate of the Yangtze finless porpoise population, there is nothreeNianhuihui“Touching the top".

　　What is more serious is the non-point source pollution in the old course of the Yangtze River in Swan Island. Hu Lianghui said that although the old course of the Yangtze River in Swan Island was marked with a red line, many beaches were occupied by neighboring farmers for historical reasons. Pesticides and fertilizers have washed into the old channel, but the old channel is relatively separated from the Yangtze River and cannot be self-purified, and the water quality in the protected area has an obvious deterioration trend. At worst, the water quality in some waters is Grade IV.

　　Wang Ding said that at present, Shishou Swan Island in the mainstream of the Yangtze River, Hewang Temple in Jianli, Hubei/Huarong Integration in Hunan and Xijiang River in Anqing.threeIn the Yangtze finless porpoise ex situ conservation area, there are2It has been isolated from the main stream of the Yangtze River, and the main stream has basically lost its function of supplementing water, improving water quality and supplementing early fish resources. In addition, the beaches around the ex-situ conservation area are occupied, and agricultural and domestic wastewater is directly discharged into the ex-situ conservation area, so the water quality of the ex-situ conservation area is seriously deteriorated. These adverse effects, if left unchecked, may lead to the Yangtze finless porpoise.“Preserve species"Population emergence“the whole army is wiped out/overwhelmed/destroyed―meet one’s Waterloo"The risk.

　　protect“Giant panda in water"it is a long way to go

　　As the flagship species of the Yangtze River aquatic ecosystem, the population status of the Yangtze finless porpoise is the most objective and sensitive to the health status of the Yangtze River aquatic ecosystem.“indicator", protect it“Giant panda in water"A long way to go.

　　First, with the help of the favorable situation of the great protection of the Yangtze River, the blank area of the Yangtze finless porpoise protection will be gradually eliminated. Studies show that the Yangtze finless porpoise has been distributed continuously in the main stream of the Yangtze River and the lake area in history. However, due to years of human activities such as cool fishing, over-exploitation of beaches and high-intensity shipping, the Yangtze finless porpoise has been far away from these habitats, forming a blank area. Some blank areas are even more than 100 kilometers long, which seriously affects the successful reproduction and gene exchange of the Yangtze finless porpoise and restricts its population recovery growth. For example, the Yangtze finless porpoise is relatively densely distributed from Ezhou, Hubei Province to Anqing, Anhui Province, but there are no nature reserves for the Yangtze finless porpoise in some sections of this area.

　　Second, attach great importance to and solve the serious degradation of ecological environment quality in ex situ conservation areas to ensure the Yangtze finless porpoise.“Preserve species"Healthy population development. On the one hand, we should speed up the restoration measures of water ecological engineering, maintain the connectivity between ex-situ conservation areas and the mainstream of the Yangtze River, control the disorderly human activities around them, vigorously reduce agricultural non-point source pollution, and continuously improve the ecological environment of ex-situ conservation areas. On the other hand, it can be studied to jointly establish a national dolphin protection park in Swan Island, Hubei Province, Baiji National Nature Reserve in Xinluo Section of the Yangtze River, and Hewangmiao, Jianli, Hubei Province/Huarong, Hunan Province integrated Yangtze finless porpoise provincial nature reserve, so as to improve the protection and management effectiveness of nature reserves and the supply capacity of ecological products.

　　The third is to improve the equipment and facilities of the Yangtze finless porpoise research and protection technology platform, and provide better scientific and technological support for promoting the artificial breeding of Yangtze finless porpoise. It is reported that the Institute of Aquatic Biology of the Chinese Academy of Sciences is one of the main scientific research institutions for the protection of the Yangtze finless porpoise.40Over the past years, the unit has established a comprehensive research and protection technology platform for the Yangtze finless porpoise, which is open to the whole world, but the main scientific research equipment and breeding facilities of the Yangtze finless porpoise aretwentycentury90In the 1990 s, Japanese organizations provided free assistance, and most of the facilities and equipment were old and damaged, so it was difficult to meet the needs of research and breeding technology development. The insiders suggest upgrading and expanding the hardware conditions of artificial breeding of Yangtze finless porpoise in this institution, so as to provide guarantee for further breaking through the important basic theory and key technical bottleneck of Yangtze finless porpoise protection.
