Cctv newsOn the afternoon of March 1st, the State Council Press Office held a series of press conferences on the theme of "Opening by authoritative departments", introducing the situation of "accelerating new industrialization, strengthening and improving the real economy" and answering reporters’ questions.

　　Xin Guobin, Vice Minister of the Ministry of Industry and Information Technology, said that in 2022, the production and sales of new energy vehicles in China reached 7.058 million and 6.887 million, up by 96.7% and 93.4% respectively, ranking first in the world for eight consecutive years. Since 2012, when China promulgated and implemented the Development Plan of Energy Saving and New Energy Vehicle Industry, the average annual compound growth rate of new energy vehicle sales reached 87%, and the cumulative promotion of new energy vehicles reached 15.96 million, nearly 16 million. China has become an important guiding force for the electrification transformation of the global automobile industry.

　　This year, the new energy automobile industry will maintain a good development trend, and production and sales will achieve steady growth. The Ministry of Industry and Information Technology will focus on promoting the work from five aspects.

　　First, we should strengthen overall planning. Further improve and perfect the coordinated promotion mechanism for the development of new energy automobile industry, and coordinate the overall work of electrification, networking and intelligent development. Focusing on technical research, popularization and application, infrastructure construction, etc., we will continue to cultivate independent brands with high innovation level, strong comprehensive ability and international competitiveness.

　　The second is to support innovation breakthroughs. We will focus on supporting leading enterprises to play a leading role and accelerate the technical research and industrial application of new systems such as batteries, automotive chips and automotive operating systems. Start the pilot of intelligent networked vehicle access and road traffic, accelerate the technical application of 5G vehicle-road coordination, and promote the coordinated development of electrification and intelligent networked.

　　The third is to further increase the promotion and application. We will carry out pilot projects for the comprehensive electrification of vehicles in public areas, and further improve the electrification level of vehicles in official vehicles, taxis, postal express delivery, sanitation and other fields. It is necessary to work with relevant departments to study and clarify the continuation policies such as tax reduction and exemption for new energy vehicles as soon as possible, and revise and issue the "double points" management method to stabilize market expectations.

　　The fourth is to improve service support capabilities. It is necessary to speed up the development of domestic resources, stabilize international cooperation and supply, and ensure the supply and price stability of key raw materials. It is necessary to improve the recycling system, strengthen key technologies such as intelligent disassembly, and improve the recycling level of power batteries.

　　The fifth is to promote open development. We will continue to implement opening-up measures in the automotive sector, give play to the role of multilateral and bilateral cooperation mechanisms, and support enterprises, research institutions and industry organizations to carry out exchanges and cooperation in the fields of trade and investment, technology research and development, and standard setting, so as to achieve win-win development.

CCTV News:This year, the global economic growth slowed down obviously, which brought great pressure and challenges to stabilizing foreign trade. However, after a series of comprehensive measures to stabilize foreign trade support policies, in the first eight months of this year, China’s import and export of goods were basically the same year-on-year. Among them, exports have achieved month-on-month growth for three consecutive months, showing strong resilience, and various localities and departments are also trying their best to increase the intensity of service enterprises.

Multi-party efforts to stabilize foreign trade measures frequently "innovate"

As a new foreign trade format with rapid development in China, cross-border e-commerce is an important way for many enterprises to obtain orders. Since the beginning of this year, in order to get more orders, many enterprises have chosen to enter overseas cross-border e-commerce platforms, but overseas platforms also have the risk of bankruptcy. How to solve the worries of enterprises? Let’s look at the practice in Ningbo, Zhejiang.　

The products of this foreign trade enterprise in Ningbo, Zhejiang Province cover furniture and household products, fitness products and holiday products. Since it was sold on an e-commerce platform in North America, it has exceeded $10 million in sales in the first year. At present, enterprises intend to enter more overseas e-commerce platforms.

Zhou Wenyi told reporters that most cross-border e-commerce platforms require sellers to open accounts in the platform. After consumers place an order for payment, it will take half a month to two months for sellers to withdraw the payment. During this period, once the platform encounters risks, the sales money of the enterprise may not be collected.

In order to enable the majority of small and medium-sized enterprises to expand the market with the help of cross-border e-commerce platform, China’s only policy insurance company — — According to this pain point, China Xinbao innovatively launched cross-border e-commerce insurance to provide security for the export of cross-border e-commerce products.

According to reports, the rate of cross-border e-commerce insurance is comprehensively determined according to factors such as insurance scale, account period, industry of the enterprise, and credit standing of cross-border e-commerce platform. Take Ningbo as an example, their insurance cost is equivalent to about 2% of the product profit. If there is a risk on the platform after insurance, China Xinbao will generally complete the fixed loss compensation within 4 months, and the compensation amount is 80% of the sales & mdash; 90%。

It is understood that since the pilot of cross-border e-commerce insurance in Ningbo, more than 10 enterprises have insured, and it is estimated that the guaranteed sales amount will exceed 1 billion yuan.

Take the initiative as a comparison standard to help foreign trade enterprises deliver orders

This year, some enterprises in China have also received many overseas urgent orders, but due to technical barriers in standards, the delivery of orders is not timely. In Yangzhou, Jiangsu Province, the local inspection and testing department took the initiative to help enterprises solve the problem of inconsistency between national standards and international standards and remove obstacles for enterprises to deliver orders.

The products of this manufacturing enterprise in Yangzhou, Jiangsu Province are widely used in offshore wind power, bridges and docks, high-speed rail subways and other fields. Since the beginning of this year, the overseas customers of products have been expanding, but many new customers require enterprises to provide product testing reports based on international standards, while the testing reports of these products were based on national standards before, which made enterprises difficult.

The enterprise found the local inspection and testing department, carefully studied these international standards after understanding the situation, and compared them with domestic standards. Through comparison, it was found that all the international standards involved had been adopted by national standards.

Liu Chang introduced that they took the initiative to face foreign customers, introduced the international standards adopted in the national standards one by one, and supplemented the corresponding explanations, so that foreign customers recognized the test report. At present, in the field of steel pipe piles, China’s testing and certification by national standards is equivalent to international standards, and it has been recognized and adopted in Canada, Australia and other countries.

Moreover, in order to complete the delivery of the order as soon as possible, the time for issuing the test report has also been greatly improved.

Set up special foreign trade credit to support enterprises to "go to sea"

Since the beginning of the third quarter, policy-oriented financial institutions have continuously increased credit support in the field of foreign trade, and helped enterprises to speed up their "going out to sea" by setting up special foreign trade credit.

At the cargo terminal of Shuangliu International Airport in Chengdu, Sichuan, the staff of this air freight enterprise are busy playing the board and sending 58 tons of e-commerce products to Europe.

Dong Zhijian told reporters that at present, the proportion of cross-border e-commerce goods they carry has increased from 10% last year to about 40%. In order to meet the cross-border transportation needs of e-commerce customers, we have been actively expanding routes this year, but now enterprises are also facing the problem of tight funds.

How to solve the financial problems faced by foreign trade enterprises? Not long ago, the Sichuan Provincial Department of Commerce and The Export-Import Bank of China Sichuan Branch issued a number of measures, including setting up a special credit line of 50 billion yuan for foreign trade and expanding preferential policies for import financing, to provide policy financial support for stabilizing foreign trade.

In response to the financial needs of this enterprise, the newly established 50 billion yuan special credit line for foreign trade soon landed its first credit business, granting nearly 2.4 billion yuan of credit to enterprises and issuing nearly 1.2 billion yuan of loans and import credit to foreign trade enterprises. With the support of financial policy, next month, enterprises will add freight routes from Chengdu to Liege, Belgium, which will not only support their own foreign trade business, but also help cross-border e-commerce enterprises to quickly "go out to sea".

　　The five major services of the Korean People’s Army have always been the object of external attention. Compared with the Korean People’s Army and other services that often appear, the appearance rate of the Korean People’s Army Air Force is very low. However, according to Korean Central News Agency’s report on November 16th, Kim Jong-un, Chairman of the Workers’ Party of Korea, Chairman of the State Council and Supreme Commander of the Armed Forces, watched the "Korean People’s Army Aviation and air defence forces Flight Commanders Combat Flight Technology Competition 2019". This event was initiated by Kim Jong-un five years ago, and it has also become a routine annual competition. Kim Jong-un hopes to further improve the flight skills and actual combat capabilities of flight commanders and combat pilots through competition competitions close to actual combat. Every flight competition, the top leader of North Korea will personally attend and give careful guidance. The purpose of this competition is to demonstrate the ability of air force fighters to destroy enemy targets and strike the ground. In this year’s air force flight competition, North Korea’s main model was publicly unveiled, and this mysterious air force once again entered the public eye.

MiG -29 (data map)

On November 16, Kim Jong-un took a group photo with the flight controllers who participated in the combat flight technology competition and achieved results. MiG -29 appeared in the photo as the background.

"Goshawk-1", the highest symbol of the Korean People’s Army Air Force, flew over the airport accompanied by air force fighters to review the flying troops.

　　After observing, Kim Jong-un said that North Korean pilots should fight with enemies armed to the teeth with great ideas and tactics. The victory or defeat of a battle is not determined by the combat data of weapons and equipment, but depends on what ideas and why you fight. The enemy who flaunts his technical superiority cannot overwhelm the superiority of the Korean People’s Army soldiers in political thought and fighting morality. Kim Jong-un also put forward the development direction of air force to develop Korean-style aviation weapons and equipment and contain the enemy’s display of aircraft technical advantages, and put forward the programmatic task of strengthening and developing the main air force.

　　As can be seen from the photos published by the official media of North Korea, MIG -29 is still the "apple of the eye" of the North Korean Air Force. Although the MIG -29 is designed to counter fighters including the American F-16, the backwardness of electronic equipment and other systems and short range have made it impossible to compete with its opponents. Previously, most of the upper parts of North Korea’s latest MiG -29 fighter were painted with dark green and the bottom was dark sky blue. At the end of January 2012, the MIG -29 was also shown in the commemorative photos taken by Kim Jong-un when he inspected the air force. From the sky, the color of the upper part of the plane is similar to that of the land, and from the ground up, the color of the bottom of the plane is similar to that of the blue sky, so the concealment performance of the plane is improved. In 2014, North Korea began to repaint the fighter plane, changing the original dark green on the upper part of the MIG -29 fighter plane into light gray with markings, which is what we see now.

MiG -29 fighter before painting

　　On April 17, 2014, Kim Jong-un inspected the Korean People’s Army Air Force and air defence forces’s No.1017th Army. He said that when he passed by the army, he made a surprise inspection to understand the flight training of fighter planes. At that time, Kim Jong-un also ordered the fighters on duty to take off and complete difficult and complicated air combat actions. The photo taken at that time was also based on MIG -29.

　　According to South Korean media reports in 2015, although the fighter planes of the North Korean Air Force are not as advanced as those of the South Korean Army, their number is already twice that of South Korea, and some old fighters will still pose a threat to South Korea. North Korean leaders have always stressed the importance of air combat, but reports from the North Korean media show that the strategy of the North Korean Air Force seems to be developing in the direction of ground attack. The North Korean media reported that Kim Jong-un praised the North Korean pilot’s "spirit of suicide bombing" and his passionate patriotism.

An -2 transport aircraft

　　Korean media said that North Korea has 300 An -2 transport planes and called them "indigenous steelmaking-class" stealth aircraft. An -2 transport plane is a two-wing transport plane developed by the former Soviet Union in the last century. It is simple to manufacture and low in cost. It has been widely used for spraying pesticides. Because of its wooden fuselage and cloth skin, it is not easy to be found by the Korean Air Force radar once an attack is launched. The DPRK also painted stealth paint for it, and modified the electronic instrument panel. In 2014, it also dispatched more than 10 An -2 transport planes to hold an exercise of airborne troops attacking Incheon Airport at night. Korean media said that what worries South Korea even more is that the An -2 transport plane equipped with rocket launchers and the Il -28 bomber can attack South Korea’s Bering Island and Yeonpyeong Island within 2-3 minutes after taking off from the North Korean Air Force Base. The Korean army should be alert to North Korea’s air force.

　　Compared with the Korean Air Force, which is equipped with a large number of third-generation aircraft, the old models of the Korean Air Force occupy the majority. The South Korean military even said, "Three days after the start of the war, South Korean fighters will be able to fly freely in North Korea’s airspace." Although the fighter plane has fallen far behind the times, the North Korean military’s flight contest may also be aimed at sending a signal to other countries, including the United States, that the Korean People’s Air Force is fully capable of defending the country.

　　Two days after observing the Air Force Flight Competition, on November 18th, Kim Jong-un, Chairman of the Workers’ Party of Korea, Chairman of the State Council and Supreme Commander of the Armed Forces, instructed the Korean People’s Army Air Force and the air defence forces Sniper Division to conduct parachute training. According to Korean Central News Agency, Kim Jong-un instructed the training after receiving the report of the training plan from the observation center. Kim Jong-un said that the snipers landed very well. After receiving the sudden order, the brigade commander and the brigade political commissar took the lead and used their troops as gods. They personally led the troops to the front in strange areas, and their combat actions were very mature and impressive. They were all brave and reliable real soldiers. Kim Jong-un expressed great satisfaction with it.

In the early morning of September 10th, Apple held a special event for new products in autumn, and new products such as iPhone 16 series, Apple Watch Series 10 and AirPods 4 officially appeared.

In this special event, the most eye-catching new products are naturally the iPhone 16 series, especially the two Pro models, which are bigger and stronger.Even Apple introduced at the time of release: iPhone 16 Pro Max is the largest display size iPhone so far.

(Source: Apple Newsroom)

In fact, there are two reasons why Pro Max is popular all over the world: First, the display screen is large enough, and the experience of playing games and watching videos is cool enough;The other is that the battery life is enough. Under the blessing of over 4000 mAh capacity and ProMotion, it is almost the king of battery life of every generation of iPhone.

When releasing the iPhone 16 series, Apple said,Thanks to the new internal layout design, the heat dissipation performance of iPhone 16 Pro (and MAX) has been greatly improved, and the battery life has been improved. The low power consumption of A18 chip and the AI function of iOS18 further enhance the endurance of iPhone 16 Pro (and MAX).

So, what is the real performance of iPhone 16 battery life? Xiao Lei bought the iPhone 16 Pro Max when he was hungry for the first time (note: it is not a "media machine", so it can be objectively evaluated without considering Apple’s feelings). What is the battery life performance of this machine? Can you refresh the iPhone life record? After two days of experience, Xiao Lei has the answer.

The battery capacity increased by 5.5% year-on-year, but it is still poor in the industry.

The most significant upgrade of iPhone 16 Pro Max compared with iPhone 15 Pro Max is that its size has become larger, from 6.7 inches in the previous generation to 6.9 inches.

Although the paper parameters have increased by 0.2 inches, Apple has used extremely narrow bezel design on both models of this generation of iPhone 16 Pro series, so there is not much difference in grip and visual perception. IPhone 16 Pro Max has a width of 77.6 mm and a height of 163 mm, while iPhone 15 Pro Max has a width of 76.7 mm and a height of 159.9 mm..

As for the weight of the whole machine, the iPhone 16 Pro Max has returned to 227g, which is roughly equivalent to the weight of the iPhone 12 Pro Max.

It is not difficult to see from the measurements that the overall size and weight of the iPhone 16 Pro Max have not changed much, but the length is longer, and the battery capacity should not change significantly.

Sure enough, according to the disassembly report, the battery capacity of iPhone 16 Pro Max is 4,685 mAh. In contrast, the battery capacity of iPhone 15 Pro Max is 4,441 mAh, an increase of about 5.5%.

(Source: techinsights)

It is worth noting that this generation of iPhone also has some differences in battery technology.The iPhone 16 Pro uses a steel case battery, while the iPhone 16 Pro Max is still an L-shaped soft bag battery.In fact, the difference between the two batteries is mainly the form and detachable design. According to the current information, Apple has not improved the energy density of the steel shell battery of the iPhone 16 Pro.

Battery technology is the hottest topic in the mobile phone market in 2024, and almost all Android manufacturers are trying to maximize the battery life. For example, the battery energy density of vivo S19 reaches 809Wh/L, which makes it possible to pack a large-capacity battery with 6000 mAh into a 7.19mm body, and the weight of the whole machine is only 193g g.

(Source: vivo)

Just looking at the technical level, the battery capacity of iPhone 16 Pro Max is still "searching" as always. Obviously, it has reached the display area of 6.9 inches, but it has not yet reached the general 5000 mAh. However, we are also very clear that the battery life of mobile phones is often not only about battery capacity, but also closely related to processor energy efficiency, system optimization and other aspects.

Then the question is coming. What is the actual endurance performance of the iPhone 16 Pro Max with less than 5000 mAh battery?

Medium battery life: extreme scenes collapse and excellent daily use.

IPhone 16 Pro Max is different from the previous generation in terms of image strategy, which means that most of the friends who will consider starting this "super cup" at this time period have more audio-visual entertainment needs, such as games and watching movies.

In the game link, we chose League of Legends Mobile Games and Ming Chao. The former is a MOBA mobile game that has been optimized in all clients at present, while the latter is an open world game with little optimization.

1 hour "League of Legends Mobile Games" experience,Power consumption is only 14%The whole fuselage is only warm, and with the phone case, you can hardly feel the heat. It is worth mentioning that iOS 18 supports automatic recognition of mobile games and starts the game mode. After entering this mode, the camera control button will no longer take effect, and friends who are worried about touching it by mistake can rest assured.

On the "Ming Chao", which has hardly been specially optimized, the performance of iPhone 16 Pro Max is more general.The measured power consumption in one hour is 18%, and the whole process is obviously heated, and the heat is concentrated in the middle of the fuselage.Perhaps it is a problem of fever, and the iPhone 16 Pro Max consumes electricity faster in this link.

I have to say that in this new product activity, Apple specially introduced the fuselage heat dissipation of the iPhone 16 Pro series, but I didn’t expect that the A18 Pro was still difficult to control in extreme scenes (you can search for the special evaluation of the heat dissipation of the iPhone 16 series by Lei Technology).

Back to everyday scenes, such as HDR video viewing, 12% power consumption in one hour, and browsing social platforms, 8% power consumption in one hour.Under the 4-hour limit test, the remaining power of iPhone 16 Pro Max is 48%.

(Source: Lei Technology Drawing)

This achievement is definitely in the middle level in the current smart phone market. After all, the iPhone 16 Pro Max has been defeated in terms of battery capacity. But only 4685 mAh battery can achieve such endurance performance, which is also very good for me.

If we put the scene in our daily life, the battery life of the iPhone 16 Pro Max does have surprises. For example, in the 8-hour test of night sleep with all-weather display turned on, only 7% of electricity was consumed; During commuting time, replying to social platforms such as WeChat and brushing Tik Tok will only consume 4% of electricity in 30 minutes.

(Source: Lei Technology Drawing)

Thanks to the optimization of iOS 18, iPhone 16 Pro Max does have good energy consumption control in daily use. According to the model of frequently replying to WeChat, occasionally brushing social platforms, and coming to two games during lunch break,It’s no problem to use it after a day.But at present, the most power-consuming scene of iPhone 16 Pro Max is 4K video recording, and about half an hour of recording will consume 17% of electricity.If you plan to take it to a concert, then charging treasure is still an essential equipment.

(Source: Lei Technology Drawing)

Although the battery life performance of iPhone 16 Pro Max is not bad, its charging speed still stays at an average of about 27W, and the peak of the network access license prompt is 45W, which lasted for 2 seconds at most, while the power of about 35W lasted for less than 2 minutes. It can be said,IPhone 16 Pro Max is a mobile phone with insufficient endurance.

Write at the end:

IPhone 16 Pro Max has once again set a new battery life record with only 5.5% increase in battery capacity, but for now, it has not opened the gap with Android flagships.

(Source: Produced by Lei Technology)

Android flagships have not used a new generation of batteries, nor have they used the SoC of 3nm process technology, so there is still much room for imagination in the future battery life. In terms of charging, Android flagships have obvious advantages, and they have been generally equipped with more than 50W wired fast charging to provide "quick blood return" ability. In this way, it is not an exaggeration to say that battery life is becoming a shortcoming of the iPhone.

After the whole experience, Xiao Lei believes that if you pay attention to all-weather endurance and there is no need for emergency recharge, then iPhone 16 Pro Max is indeed a good choice; If you value long-term game life, then iPhone 16 Pro Max may not be suitable for you. Of course, if you are used to carrying a charging treasure with you, everything is not a problem.

　　Recently, the increase of adenovirus infection in many places has attracted people’s attention.

　　What is adenovirus? What are the symptoms after infection? How to prevent it? Let’s get to know each other!

　　What diseases can human adenovirus cause?

It is reported that the sanctions are mainly aimed at Mill payment system, Russian financial institutions and their military industrial bases, as well as future energy production and other fields. According to the US Treasury Department, this is the "largest sanctions action" by the United States against Russia since Russia launched a special military operation against Ukraine on February 24, 2022.

The European Union and Britain have also joined the new round of sanctions against Russia. Acting Deputy Secretary of State victoria nuland declared that the new sanctions imposed on Russia by the United States and the European Union would be "devastating" and would create obstacles for Russia to evade the existing sanctions.

Being abused by Biden, Putin responded with ridicule.

In response to the swearing abuse by US President Biden, Russian President Vladimir Putin responded to reporters: "This shows that Biden is more suitable to be the president of the United States."

It is reported that Biden made rude remarks to Putin at a fund-raising event in San Francisco on the 21st local time, saying that "there are’ crazy bastards’ like Putin in the world, so that we always have to worry about nuclear conflicts".

Reuters said that on 22nd, when asked about Biden’s rude remarks by Russian state television, Putin first smiled sarcastically, bit his lip, and then looked at the ground. Later, Putin said with a smile: "When we talked not long ago, you asked me who we would prefer to be the future president of the United States for Russia. I said that we are ready to cooperate with any American president. But I think Biden is a more suitable American president for Russia. Judging from his remarks now, I think this is absolutely correct. "

A middle school student in the United States was dissatisfied with the school’s request to cut his hair short and took the governor and the state attorney general to court.

According to a number of American media reports, an 18-year-old middle school student in Texas, USA, was dissatisfied with the school’s request that he must cut his hair short, and not only took the school to court, but also the governor of Texas and the state attorney general, saying that he had been illegally persecuted by them.

According to American media reports, the middle school student sued the school and the government on the basis of an anti-hair discrimination bill that came into effect in Texas last September. The English name is CROWN Act. The law requires local schools, employers and other institutions not to discriminate against those who have hair styles with national and cultural characteristics, such as some common hair styles of black Americans.

However, on Thursday, local time, the judge who heard the case of students suing the school ruled that the school won the case, on the grounds that although the laws of Texas protect national characteristic hairstyles from discrimination, there is no provision in the law to protect the length of hair, so the judge can only decide the case according to law and cannot invent anything that is not in the law, otherwise it will overstep the functions of the legislature.

　　Original title: From Epidemic Prevention Station to CDC

　　Since the outbreak of the COVID-19 epidemic, Beijing CDC at all levels, as a front-line professional force, has played an important role in fighting the epidemic. From the initial health and epidemic prevention station to today’s CDC, how did Beijing’s health and epidemic prevention work step into a new era of public health from a blank sheet of paper?

　　Health and epidemic prevention stations were set up in 1950s.

　　Before the founding of New China, Beijing’s health and epidemic prevention work was almost blank. Plague, cholera and smallpox all occurred and prevailed, and people’s lives and health were greatly endangered.

　　After the founding of New China, Beijing attached great importance to health and epidemic prevention, quickly eliminated smallpox and relapsing fever and prevented the occurrence of plague and cholera. Infectious diseases such as diphtheria, whooping cough, measles and polio, which seriously endanger children’s health and life, have also been basically controlled. By the mid-1950s, the focus of health and epidemic prevention in the city had shifted to the prevention of measles, dysentery and Japanese encephalitis.

　　In October 1953, Beijing Health and Epidemic Prevention Station was established and became the municipal epidemic prevention and health supervision department.

　　What was the Beijing Health and Epidemic Prevention Station like at that time? On July 11th, 1955, Futang Zhu, a deputy to the National People’s Congress and a pediatrician, published an article entitled "I visited suburban rural areas and health and epidemic prevention work" in the 3rd edition of this newspaper, which wrote that there are three new buildings in the north of the Municipal Infectious Disease Hospital, one is the office of the Beijing Health and Epidemic Prevention Station, the other is the disinfection station, and the other is the passing room and disinfection treatment room. Designed by Soviet experts, it is specially designed to disinfect patients and clothes with infectious germs. It is divided into two parts, men and women, each with a registration room, a barber shop, a dressing room and a bathing room. The two clothes are sent to a central disinfection room from both sides. The high-pressure sterilizer in the disinfection room is as big as a locomotive. If the cotton-padded clothes are disinfected, 150 sets of cotton-padded clothes can be disinfected in about 30 minutes with 10 pounds of steam pressure.

　　At that time, the function of Beijing Health and Epidemic Prevention Station was to inspect and supervise industrial hygiene, environmental hygiene, food hygiene and school hygiene on the one hand, and to investigate and deal with epidemics on the other hand, to organize large-scale vaccination work, and to organize the masses to carry out patriotic health campaigns and give technical guidance.

　　Later, the city’s health and epidemic prevention institutions continued to improve and perfect, and district-level health and epidemic prevention stations were also established in various districts. However, due to the limited conditions, in 1950s, epidemic prevention stations in the whole city only carried out irregular supervision and inspection on the hygiene of fur and leather industry and high-temperature workshops and toxic workplaces in related industries with poor working conditions, as well as some food industries, cold drink manufacturing and selling industries, schools and other units, so the depth and breadth of hygiene and epidemic prevention need to be improved. (Beijing Daily, 1st edition, February 28, 1984, "Strengthening Health and Epidemic Prevention in this Municipality and Actively Building a Civilized and Healthy Capital")

　　2. Organize patriotic health campaign

　　Among the many tasks organized by health and epidemic prevention stations, the patriotic health campaign centered on "eliminating four pests" in the 1950s and 1960s is probably the most memorable one for the citizens.

　　According to the newspaper’s 2nd edition of September 6th, 1956, "City and District Epidemic Prevention Stations are Vigorously Killing Mosquitoes and Flies", the city health and epidemic prevention station dispatched a large number of electric spray trucks and motorcycle spray trucks to kill mosquitoes and flies, among which the electric spray trucks only sprayed an area of more than 450,000 square meters in 45 days. Disinfectors in various districts also assisted relevant departments to use drugs to kill flies in garbage dumps and their surrounding households, and shared drugs to spray more than 1,000 houses and more than 30,000 square meters of garbage dumps. In rotten vegetable piles, residents’ outdoor toilets and septic tanks, the epidemic prevention station also uses drugs to kill maggots.

　　In order to provide scientific basis for the city’s fly control and disease prevention work, the staff of Beijing Health and Epidemic Prevention Station conducted many investigations and studies on fly control. They set up fly index survey points, which are distributed in various parts of the city: some are located in institutions; Some are located next to public canteens; Some are located in the corner of the food processing workshop. Every month and every ten days, the staff should put the fly cages on each investigation point on time, and at the same time bring the caught flies back to the laboratory, identify them by species, register and analyze them respectively, understand the types, living habits and breeding laws of flies, and test the effect of pesticides. (Beijing Daily, 2nd edition, July 6, 1962, Investigation on Fly Killing in Municipal Health and Epidemic Prevention Station)

　　City and district health and epidemic prevention stations also organized the masses to carry out rodent control activities. The staff of the health and epidemic prevention station investigated the distribution density and reproduction law of rats, summed up some methods and measures to eliminate rats, and promoted them to institutions, factories, schools and so on. Later, this work became a regular health work in the city. (Beijing Daily, 2nd edition, November 1, 1963, Achievements in Rodent Control in this Municipality)

　　3 prevention and treatment of chronic diseases has gradually become the "highlight"

　　With the development of the times, the focus of health and epidemic prevention in Beijing has also changed, paying more attention to how to improve people’s health.

　　In June, 2000, based on the Beijing Health and Epidemic Prevention Station and other units, the Beijing Center for Disease Control and Prevention was formally established, and its functions were expanded to prevent infectious diseases, chronic non-communicable diseases, common diseases of students, emergency response to public health emergencies, national health education, public health protection and many other contents. Since then, district-level CDC has also been established.

　　The prevention and treatment of chronic diseases has gradually become the "highlight" of disease control. According to the 16th edition of "Beware of the rejuvenation of patients with chronic diseases" published by this newspaper on December 26th, 2001, since 1970s, the disease spectrum of Beijing residents has changed significantly, infectious diseases have been basically controlled, and chronic diseases such as cardiovascular and cerebrovascular diseases and malignant tumors have become the main diseases threatening Beijing people’s health. In order to control the rising trend of chronic diseases, after 2000, Beijing Center for Disease Control and Prevention established chronic disease demonstration sites in eight urban areas of the city, and selected representative residential communities to investigate five chronic diseases and behavioral risk factors, including hypertension, diabetes, tumor, coronary heart disease and stroke.

　　In 2002, the Beijing Center for Disease Control and Prevention randomly selected 1,240 families from the whole city for nutritional and health status survey, and learned about the nutritional status of residents in this city and the incidence of chronic diseases related to it through daily food and nutrient intake, eating habits and other information. (Beijing Daily, 5th edition, August 19, 2002, Fine Calculation of Oil, Salt, Sauce and Vinegar)

　　Under the scientific guidance of the disease control department, Beijing people’s health concept has become fashionable, and investing in health has become a fashion. Beijing National Physical Fitness Testing Center receives many citizens who come to test their physical fitness every day, spend some money to find out their physical fitness, and let experts tailor a fitness plan for themselves by the way. In the past, vaccination was a "patent" for children. After entering the new century, adults and the elderly have joined the army of injections, and preventing diseases before they happen has also become an investment. (Beijing Daily, 1st edition, October 7, 2002, "Beijingers live ten years longer than one year")

　　4. Improvement of epidemic reporting system in SARS

　　In 2003, the sudden SARS epidemic ravaged Beijing. As the main force of prevention and control, the disease control department bravely shouldered the heavy burden.

　　On April 10, 2003, the first edition of "Extraordinary Warrior" recorded the scene of that year: it was late at night, and the Beijing CDC was still brightly lit. The 60 members of the SARS emergency team are still busy. Several hotlines on the desk kept ringing, citizens kept asking about SARS symptoms and prevention methods, and eight trained business backbones took pains to answer various questions. At the end of the day, everyone has to answer dozens or even hundreds of phone calls, and they are often too tired to even eat. In the health and epidemic prevention emergency command center, the monitoring reports of all districts and counties are collected at any time on the huge screen, and the epidemiological investigation team members summarize the information of the day. If a suspected SARS patient is admitted to the respiratory clinic of a hospital, the epidemic prevention personnel will arrive at the scene half an hour later, and track his upper-level source of infection and close contacts to cut off the source of infection.

　　In April of that year, a strict epidemic reporting system was established in Beijing. Every hospital has a statistical reporter. The urban CDC should accurately report the epidemic situation to the municipal CDC within 6 hours, and the suburbs should complete this work within 12 hours. (Beijing Daily, 3rd edition, April 26, 2003, "The city has formed a perfect SARS epidemic reporting and prevention and control system")

　　After SARS, great progress has been made in the construction of epidemic reporting system and system in Beijing. Chen Liquan, then director of the Dongcheng District CDC, said that the hospital could report the epidemic situation directly to the Ministry of Health through the computer network, and at the same time report it to the local grassroots CDC by telephone and fax for epidemiological investigation and handling. The double reporting system makes the information construction of disease control more perfect. (Beijing Daily, 2nd edition, October 13, 2003, "Prevention must be based on SARS")

　　5. Establish a four-level early warning of infectious diseases.

　　Due to the continuous discovery of new pathogens and related infectious diseases around the world, the situation of health and disease prevention is grim. Beijing is also striving to build a perfect public health safety system and continuously improve its ability to respond to public health emergencies.

　　In November 2004, the Emergency Plan for Public Health Emergencies in Beijing was issued, which consists of the emergency plans for public health emergencies such as influenza, avian influenza, plague, cholera and hepatitis, and food poisoning and acute occupational poisoning. The epidemic situation of infectious diseases is divided into four levels according to different intensities, with particularly serious infectious diseases as the first level, major infectious diseases as the second level and major infectious diseases as the third level. The general epidemic situation of infectious diseases is Grade IV, and the corresponding designated hospitals are enabled according to the early warning level, and the corresponding number of beds are enabled according to the intensity of the epidemic, and the clinically diagnosed and suspected patients are treated respectively. (Beijing Daily, 1st edition, November 5, 2004, "Outbreaks will be divided into four levels of early warning")

　　In 2005, Haidian took the lead in launching a public health safety broadcasting system in China, which provided early warning of infectious diseases, food poisoning, occupational poisoning and drinking water pollution incidents according to various public health events over the years. (Beijing Daily, 6th edition, February 28th, 2005, "Public Health Safety Broadcasting System Launched in Haidian")

　　Drawing lessons from SARS, Beijing’s public health construction has been carried out step by step. Since then, Beijing has taken the lead in the prevention and control of avian influenza, influenza, norovirus and hand, foot and mouth disease. Today’s Beijing has entered a new era of public health.

Next, we will bring the evaluation and introduction of DJI Mavic 3 Classic UAV.

Appearance: consistent with Mavic 3 family design

The design language of DJI Mavic 3 Classic is consistent with the Mavic 3 family, and the biggest difference is the modeling part of the image system.

Storage protective cover of DJI Mavic 3 Classic

Storage protective cover of DJI Mavic 3 Classic

DJI Mavic 3 Classic continues Mavic 3′ s storage protective cover design, which can protect the whole camera module, obstacle avoidance vision camera and bind the blades at the same time. With this storage protective cover, we don’t have to worry about damage even if we carry DJI Mavic 3 Classic alone.

It can be seen that the DJI Mavic 3 Classic still adopts the folding method, and the volume control of the storage is excellent, which is also convenient for us to travel and carry. After deployment, the fuselage of DJI Mavic 3 Classic is larger than that of Air Series, but thanks to its excellent configuration and aerodynamic design, the wind resistance of DJI Mavic 3 Classic is 35% lower than that of Mavic 2 Pro. This plays a vital role in improving endurance.

4/3 format Hasselblad camera of DJI Mavic 3 Classic

It can be seen that compared with DJI Mavic 3, the biggest difference of DJI Mavic 3 Classic is the design of the lens part. DJI Mavic 3 Classic cancels the telephoto lens design, improves the cost performance, and can better satisfy users who only want to experience the Hasselblad camera experience with ultra-high quality. The image system of DJI Mavic 3 Classic adopts a CMOS sensor design with 20 megapixels and 4/3 frames, which can shoot videos with the highest specifications of 5.1K 50P and 4K 120P, with a native dynamic range of 12.8 files, and supports Hasselblad Natural Color Solution (HNCS) and 10bit D-Log.

Cooling system of DJI Mavic 3 Classic

Cooling system of DJI Mavic 3 Classic

In order to achieve a better flight and aerial photography experience, DJI Mavic 3 Classic provides a large number of heat dissipation designs. At the top of the fuselage, there are large air inlets and fins at the head and tail. In particular, the design of a large-area heat dissipation area at the bottom of the fuselage can better help the drone to cool down during operation.

Safety blade of DJI Mavic 3 Classic

DJI Mavic 3 Classic also provides safety blades, which is consistent with Mavic 3 family. The safety blade is different from the previous UAV blades, and its end is made of plastic material (orange part), that is, the end of the blade is soft. DJI came to the conclusion through experiments that, even if the safety blade passes through an object during flight, it will generally only leave a scratch, and it will not be directly split. But even so, it is not recommended that you try, which may cause a bomber or your own safety hazards.

Card slot and interface of DJI Mavic 3 Classic

The card slot and interface of DJI Mavic 3 Classic are designed above the battery with a protective cover. DJI Mavic 3 Classic adopts USB-C interface and supports TF card (Micro SD card). At the same time, the drone itself has 8GB of body memory for emergency use.

Battery and charging housekeeper of DJI Mavic 3 Classic

Fast charging charger of DJI Mavic 3 Classic

The battery of DJI Mavic 3 Classic, like Mavic 3, has the capacity of 5000mAh and 77Wh, and the voltage is 15.4V. This battery provides the longest battery life of 46 minutes and the longest cruising range of up to 30 kilometers.

In addition, DJI Mavic 3 Classic is equipped with a GaN (gallium nitride) fast charging charger with a power of 65W, which is compatible with PD protocol. Besides charging the battery of DJI Mavic 3 Classic, it can also charge laptops, cameras and other devices.

Image system: 4/3 format Hasselblad camera is very powerful.

DJI Mavic 3 Classic inherits the design of this series of 4/3 format Hasselblad lenses, with 20 million pixels, equivalent to 24mm focal length and aperture range F2.8-F11. The 4/3 frame is what we often call M4/3 frame. However, in order to meet the take-off weight and size requirements of UAV, DJI and Hasselblad jointly developed a brand-new design.

That is to say, this lightweight and compact UAV lens can not only meet the requirements of image quality and resolution of 4/3 frames, but also meet the requirements of size, weight and power consumption required by DJI Mavic 3 Classic.

4/3 frame is the largest sensor size of consumer UAV at present. As the saying goes, the bottom is the first step to crush people. Thanks to the CMOS sensor with the bottom, DJI Mavic 3 Classic can bring excellent photography and video capabilities, not only better dynamic range performance, but also better color performance and resolution.

At the same time, in the dark environment, 4/3 frame can bring better noise suppression effect and make our dark video picture more pure. The newly added night video, cruise control and other functions can better serve users, so that users who have just stepped into photography can easily complete the shooting of various styles of videos.

The video specification of DJI Mavic 3 Classic also inherits the strength of Mavic 3 family, and supports the video specification of up to 5.1K 50P, and also supports the slow-motion video capture of 4K 120P. DJI Mavic 3 Classic supports 10-bit D-log, which provides a foundation for our later stage and color matching space. Supporting Hasselblad Natural Color Solution (HNCS) can make its color effect even better.

Through the video, we can easily understand the core competitiveness brought by the 4/3 format Hasselblad camera. Video is not only rich in details, but also remarkable in color expression, which can restore natural colors very accurately, as if it were the color appearance of the real world seen by our naked eyes.

In addition, the video itself has a dynamic range of 12.8 files, which is very helpful for later repair and adjustment. That is to say, with the help of DJI Mavic 3 Classic, we can shoot professional-grade videos, which can be used for video production in professional fields.

In terms of focusing, the experience effect of DJI Mavic 3 Classic is the same as that of DJI Mavic 3, and the focusing experience is excellent, just like we are using the camera’s focusing system. For users, it is more reassuring to hand over the focus to DJI Mavic 3 Classic to complete it by themselves.

In the photo section, we can see that the performance of DJI Mavic 3 Classic is still remarkable. After all, it is a 20-megapixel M4/3 format camera that can fly to the sky. 20 million pixels is close to the mainstream pixel specifications of the current camera, so the photos brought by DJI Mavic 3 Classic have delicate analytical performance, which can present the details clearly and completely.

The 12-bit RAW format file provides a very large space for our later period, which can make the photos more professional. When you encounter good scenery, you can use this 4/3 format Hasselblad camera to take pictures.

Obstacle avoidance: You can fly safely by avoiding obstacles in all directions.

When Mavic 3 in DJI was launched, an upgrade that surprised users was its obstacle avoidance system, and DJI Mavic 3 Classic completely inherited this obstacle avoidance capability. In other words, DJI Mavic 3 Classic supports omni-directional obstacle avoidance capability, which is the best performance of consumer drones in obstacle avoidance at present.

What is omni-directional obstacle avoidance, that is, DJI Mavic 3 Classic can sense the 360-degree spherical range of the whole body. We often say that up, down, front, back, left and right can avoid obstacles in these directions.

DJI Mavic 3 Classic’s down-looking obstacle avoidance vision sensor, ToF ranging sensor and fill light.

DJI Mavic 3 Classic has designed eight vision sensors, including two fisheye cameras at the front, back and bottom, which provide a 185-degree viewing angle and can cover a wider visual area. There are also two wide-angle cameras at the top of the fuselage, and there are ToF ranging sensors and fill lights below. Together, these designs provide powerful hardware support for obstacle avoidance vision.

In terms of software, DJI Mavic 3 Classic supports APAS 5.0 obstacle avoidance system. Thanks to the improvement of system algorithm, it can help DJI Mavic 3 Classic to avoid obstacles faster, more dexterous and smarter, and ensure the UAV to fly and take aerial photos safely.

When flying, DJI Mavic 3 Classic can identify obstacles and avoid obstacles by itself, even if it only makes the plane fly forward. We can choose emergency stop or detour in the menu, and detour can also choose safe or radical, which has achieved different results. No one will take corresponding measures to avoid obstacles according to our choice.

With excellent obstacle avoidance ability, it can bring excellent intelligent following ability to users. When we are outdoors, whether we let DJI Mavic 3 Classic follow our own walking and running shooting, or follow our own riding and driving shooting, we need the powerful following ability and obstacle avoidance ability of the drone to work together.

The overall performance of DJI Mavic 3 Classic is excellent. Because its obstacle avoidance system is smarter, it will have better path planning when following, and at the same time, its recognition ability is more stable, and it can keep up and keep up well.

Return flight: advanced intelligent return flight efficiency

DJI Mavic 3 Classic also has advanced intelligent return function. In the past, the unmanned aerial vehicle (UAV) was very unwise to return home. It needed to fly to a preset altitude, then fly back to the take-off point, and then descend. If you encounter a tall obstacle in the middle, you need to continue to climb the height and then cross the obstacle, which is time-consuming and electricity-consuming. Therefore, when we experience aerial photography, we will reserve enough power for the drone for returning flight. In this way, our experience time of aerial photography and flight will be greatly reduced.

DJI Mavic 3 Classic’s return flight ability is more intelligent and fully inherits the new skills of Mavic 3 family. During the flight, the visual processing engine of DJI Mavic 3 Classic can scan the surrounding environment in real time and build a three-dimensional environmental map. In this way, when returning, the drone will find a safe and efficient path to return.

If we return in the wild, the performance of DJI Mavic 3 Classic will not be particularly outstanding. After all, there are not too many obstacles in the wild to prevent us from returning. If you are returning in a city, especially in a city with many high-rise buildings, the intelligent return performance of DJI Mavic 3 Classic can be revealed. When encountering a tall obstacle, the drone does not climb or leap, but cleverly bypasses the obstacle and continues to return, which can save a lot of return time and electricity, and let us have more time to experience flying and aerial photography.

Image transmission: the picture is clear and stable.

The evaluation product we got this time is the remote control version of DJI Mavic 3 Classic RC, which means we got the remote control version with screen. However, both the remote controller DJI RC with screen and the remote controller DJI RC-N1 without screen have the same image transmission ability. DJI Mavic 3 Classic supports DJI O3+ image transmission, and can support the image transmission distance of up to 15 kilometers, and the transmitted images reach 1080P 60fps.

With this set of graphic transmission system, the experience of our daily use of DJI Mavic 3 Classic is directly improved. The first is the improvement of the picture transmission. The picture of 1080P 60fps is not only clear but also very smooth, which allows us to better view the flight picture and control the composition and flight. Although it is impossible to reach the image transmission distance of 15 kilometers in a city with serious interference, this image transmission system is still very stable and can ensure our safe flight experience. Even if it is disconnected, the plane can return intelligently, so don’t worry too much.

Endurance: 46 minutes can be a happy aerial photography.

The endurance of DJI Mavic 3 Classic is also 46 minutes, which is consistent with the products of Mavic 3 family. The test version we get will contain a battery itself, as well as two extra batteries in the battery pack and the charging housekeeper, which will ensure that we have a long flight experience and aerial photography time. At present, the 46-minute battery life ranks second among the consumer-grade UAVs in DJI, and the first one is the 47-minute battery life of the Mini 3 Pro with long battery life.

Battery and charging housekeeper of DJI Mavic 3 Classic

In the past, the average battery life of consumer-grade UAV products in DJI was around 31 minutes. Suppose we fly for 31 minutes, excluding the take-off, composition and adjustment time, which is about 10 minutes, and excluding the return time of about 6 minutes, our actual shooting time is only 15 minutes. The battery life of DJI Mavic 3 Classic is 46 minutes, so the actual shooting time can reach 30 minutes.

Summary: cost-effective flagship consumer drone

So far, our evaluation and introduction of DJI Mavic 3 Classic has come to an end. DJI Mavic 3 Classic has the same flying ability, obstacle avoidance ability, image transmission ability, endurance and so on as the consumer flagship drone DJI Mavic 3. At the same time, it also has a Hasselblad camera with 4/3 frame, which provides professional-grade imaging ability. The only difference is the telephoto camera. Of course, DJI Mavic 3 Classic has many functions that serve users, such as time-lapse photography, focus following, master shots, etc. Because these functions are completely consistent with the performance of Mavic 3, we will not repeat the test and introduction.

DJI Mavic 3 Classic is a differentiated Mavic 3 family member. Compared with the current Mavic 2 Pro and Air 2S, DJI Mavic 3 Classic has flagship flight and aerial photography capabilities, which can be described as a comprehensive upgrade, and the intensity of the upgrade is still qualitatively improved. At the same time, it has high cost performance and can fully meet the upgrade needs of users.

At the same time, based on the functions of Mavic 3 family, DJI Mavic 3 Classic has also added functions such as cruise control and night video, which allows users to achieve more diversified creations.

If you just need to upgrade and think that the price of Mavic 3 exceeds the budget, then the price of DJI Mavic 3 Classic is your best choice. Through our actual experience, this drone is enough to meet the use and shooting needs of professional users, both in flight capability and imaging system.

In particular, video creators, aerial enthusiasts, video teams and studios can fully consider this product because it is a flagship drone with high cost performance.

In the future, more new members will join in, enriching the category of consumer-grade flagship drones, and users can choose DJI drones that are more suitable for them according to their own needs and budgets.
