Recently, there have been new products one after another, especially when the pre-sale price was just announced some time ago, and now there is another model with the word "Bing" released. Its high production level makes many brands feel ashamed.

Recently, its new small SX11 has been officially named as the first model based on the self-developed BMA modular platform. This main model, which is also highly expected, now seems to be ready only for price, so we might as well predict the price of this car.

Sort out the positioning of Colorful in Geely SUV models

As mentioned earlier, this period of time was very productive. Coupled with its existing models, it could be said that it now had a large number of products, and most of them were models. In this way, we must first understand the position in the product matrix, so that we can simply infer the price range.

No matter from the design, or naming rules, have to let people associate him with, coupled with some basic parameters and manufacturers of some information to compare, it is not difficult in its products, positioning should be between and. So we can guess that the price may be roughly between 8-150,000 yuan range.

Infer the price of Colorful from the same brand products

The products of its "Bo" and "Bing" characters can be said to be "neat and tidy", and the corresponding models are mostly models of different styles at the same level. Then we might as well compare their prices (currently pre-sale prices) from right and right.

▲ Geely Boyue

▲ Geely Binrui

▲ Geely Borui

Since it is equipped with the jointly developed 1.5T, we will only choose the other three models to compare. First, let’s take a look at the entry-level versions of these models.

Through a simple calculation, it is not difficult to conclude that the entry-level model is about 54% more expensive, and if it follows this pricing ratio, then we can roughly calculate the starting price of 71,300 yuan.

Then next, we can also calculate the upper limit of the price range based on the price of the highest matching. The price of the top version is 51.3% higher, and it can be calculated that the top matching price may be 105,600 yuan.

In this way, we have roughly determined the possible price range, which may be 7.13-10 5,600 yuan or so, but the price obtained by arithmetic is very inaccurate. After all, if it is really this price, it is estimated that consumers will laugh crazy first, and it is equipped with a stronger 1.5T.

A comparison with competitors of other brands

So in order to predict the price more accurately, we also need to compare it with competing models of other brands in the market with similar configurations. At present, it can be compared with competing models, including those that are small in size and similar in positioning. From these models, choose the 1.5T version to compare to predict its price.

In terms of size, it is indeed smaller than other compact models, but it is similar to those of the same class.

However, if you look at the power, even though it is equipped with 1.5T, it can be seen that in the case of the same level, the power data is the best. 130kW and 255N · m, matching 7DCT wet, the 100-kilometer acceleration can reach 7.9 seconds.

In addition, it is understood that new energy vehicles such as PHEVs will be launched simultaneously in the future, and they will also be equipped with a wealth of intelligent safety equipment and L2 autonomous driving assistance technology.

So in general, if it is "small", it is better than other brands’ models because of its stronger power. Although the internal space may be slightly inferior to the competing models, I believe it will be very cost-effective in terms of configuration compared with other products.

Considering past pricing habits and increasingly confident brand power, perhaps the price of this one will be around 8.28-12 6,800 yuan.

And there is also a speculation here, that is, whether the future will launch a lower power 1.0T model, if so, then the entry-level model, the price may enter the 80,000, predicted to be around 79,800 yuan.

In addition, according to the new product launch to the market, most of them have a warm-up period of about three months, so this car is likely to make consumers wait until the end of the year.

On the evening of May 16, the seventh episode of "Extreme Challenge" was broadcast. Because the movie "Antique Bureau Middle Bureau" was about to be released, this episode was themed around the movie. In addition to the resident guest Lei Jiayin, the show also invited two guests, Xin Zhilei and Li Xian, both of whom were starring in "Antique Bureau Middle Bureau".

It can be seen that the program has indeed given Lei Jiayin enough space. In fact, the theme of the movie will not make the audience disgusted, but there is some freshness, and this program also adds the elements of the current popular role play tabletop game and secret room escape. It was originally very watchable, and it also regained some of the feeling of the previous seasons of "Extreme Challenge", but after watching it, it was still disappointing.

After the latest episode aired, the Douban page of the show was flooded with bad reviews. Many netizens said they "don’t want to give one star", and some netizens accused the show of "inserting variety shows in advertisements" and the script was getting worse and worse. Looking at this episode, there are at least three points that are really disappointing.

Everything follows the script, the game must be too obvious

In order to cater to the movie "Antique Bureau Middle Bureau", the first part of the show is that the guests choose their own "identities", which are closely related to the characters in the subsequent role-playing tabletop game.

Through the program, it can be seen that the staff moved eight sets of clothes to the stage, corresponding to the identities of the second child, female student, male student, son, beggar, seafarer, butcher and shopkeeper. The program team used everyone to count and quickly call out each other’s names to determine the order of identity selection.

In fact, if these costumes are not provided, there will definitely be no problem with this game process. Let the guests randomly select in order, in fact, to prove that the follow-up game sessions are random, so that it is fun.

But the problem lies in the costumes, not to mention that the eight identities are male and female, and it is difficult to swap the costumes between men and women. The seven male guests on the scene are tall, short, fat and thin. It is unlikely that the program team will be like the movie crew. For the game setting, eight sets of costumes are customized for each guest. All costumes must be the eight sets on stage.

But in the end, everyone’s clothes fit perfectly, and it was obviously tailor-made. This meant that the game session in which the numbers were reported to determine the order of clothes was just a show. Everyone had already determined their roles, and they had long been familiar with the follow-up game sessions and got their own scripts. This proved that this issue of "Extreme Challenge" did not have random performances at all, it was all preset performances.

The low-intelligence game lasts for time, and the program is seriously watered down.

Because the characters had been predetermined for a long time, naming and counting had become meaningless "garbage time" that was helpful to the progress of the game. Moreover, it was also very low-minded, including the "baa baa sheep" that had appeared in the previous show.

Indeed, as netizens said, there were indeed too many advertisements in the following links, not only to expose the advertisements, but also to be broadcast orally by guests. For example, after solving the problem, Guo Jingfei’s oral advertisements were particularly deliberate, completely destroying the rhythm of the game. Jia Nailiang and others used the microphone of the sponsored brand to continue Karaoke, which was also very boring.

Guests are lazy and can’t bring the game, and the secret room will give the answer directly

Putting aside the full of gimmick role play tabletop games, the escape room alone is an eye-opener, and once again shows the lower limit of the show.

Unlike ordinary secret room escapes, which require careful search for clues, the clues given in the program are very obvious. Each room has a red password box, which is unlocked through the given materials, and opening the box is considered customs clearance.

The first group to try was Deng Lun, Yue Yunpeng, and Jia Nailiang. The decryption method was very simple.

Another group of Lei Jiayin, Xin Zhilei, and Huang Minghao calculated the four-digit password according to the scale of the hour and minute hands. There were paintings on the wall and a clock for them to operate. In fact, as long as the three of them use their brains and have a little patience, it will definitely not take much time to find the correct unlocking password.

But the performance of the guests was disappointing. Lei Jiayin was very impatient. He glanced at the clock and directly said "It’s over, I can’t do it at all".

Huang Minghao tried his best to find the answer, but in the end he didn’t succeed. Obviously, the three guests didn’t want to work hard, they just wanted to be lazy. There was no way to continue the game session like this, so they just asked them to open the door directly.

At this point in the game, fairness is lost and it is completely meaningless.

In addition, Guo Jingfei’s group is also very speechless. The arithmetic answer is completely given by the teacher. The purpose is to advertise the sponsored online class brand.

In addition to not wanting to guess the password, the guests also used violence to disassemble it. Although breaking the rules of the game is the tradition of "Extreme Challenge", at this node, without using their brains to violently unlock the lock, making the entire game link meaningless.

Xin Zhilei’s last password lock had no lower limit, and the program team actually pasted a password note next to the box, giving the answer, is this fooling the guests or fooling the audience? It can be said that this show is not a challenge to the guests, but a challenge to the bottom line of the show and a challenge to the audience’s tolerance. What do you think?

On October 15, China successfully launched two Beidou-3 global networking satellites. Image source: Screenshot of the report of The Next Web website

　　China Daily Network, October 16. At 12:23 on October 15, China successfully launched the 39th and 40th Beidou navigation satellites at the Xichang Satellite Launch Center in the form of "one arrow and two satellites". According to the plan, two medium-circle earth orbit satellites and one geosynchronous orbit satellite will be launched in the future, and the basic system will be completed by the end of this year to provide services to countries related to the "Belt and Road Initiative".

　　According to the US science and technology website The Next Web News Network reported on the 15th, the successful launch of the Beidou binary satellite is of great significance **. China has developed the Beidou satellite navigation system not only to meet its maintenance ****, but also to develop the social economy. According to reports, the positioning accuracy of the Beidou satellite navigation system can reach 2.5 meters, which is better than the US GPS with a positioning accuracy of 20 meters. Therefore, the Beidou satellite navigation system has important strategic significance.

　　Beidou satellite navigation system has a wide range of application fields, including communication, mapping and geographic information, meteorological monitoring, disaster relief and mitigation, emergency search and rescue, and even plays a crucial role in China’s unmanned technology.

　　The Beidou satellite navigation system not only benefits China, but also other countries. There are three types of Beidou satellite navigation systems: Beidou-1, which is the first generation of Beidou system, can provide nationwide timing and navigation and positioning services; Beidou-2 services cover the Asia-Pacific region; and the upcoming Beidou-3 can provide services to countries along the "Belt and Road Initiative".

On October 15, 2018, China successfully launched two Beidou-3 global networking satellites. Xinhua News Agency (photo by Liang Keyan)

　　The Beidou satellite navigation system has been in development for a long time. As early as the 1980s, China planned to develop its own navigation system and officially started construction in 1994. In 2000, the first generation Beidou navigation satellite (Beidou-1) was launched into space.

　　China plans to launch 35 satellites in medium-circular earth orbit from a distance of 22,000 kilometers by 2020. In addition, it will launch another five satellites in geosynchronous orbit with an altitude of 35,786 kilometers and three satellites in inclined geosynchronous orbit. The 39th and 40th Beidou navigation satellites just launched are also the 15th and 16th networking satellites of the Beidou-3 system.

　　Over the years, the Beidou satellite navigation system has become increasingly important to the "Belt and Road Initiative" initiative. In 2014, the China Satellite Global Service Alliance (ASAS) called it the "Space Silk Road", a project aimed at using satellites, launch services and ground infrastructure to support related industries and service providers around the world. At present, the demand for satellite services is increasing year by year, and the continuous development of Beidou satellite navigation system can be described as the right time.

　　Thanks to the development of smart technologies such as wearable devices, the Internet of Things, drones, and driverless cars, the market for global navigation satellite systems (GNSS) is currently quite prosperous, including products and services that enable positioning functions.

　　According to the Global Navigation Satellite System Market Report released in 2017, the number of GNSS navigation devices (mainly smartphones) in the Asia-Pacific region will grow from 1.90 billion in 2015 to 4.30 billion by 2025, exceeding the sum of the European Union and North America, and is therefore expected to be the main driver of market growth in this field.

　　In 2016, the output value of China’s GNSS and positioning services market reached 33.24 billion yuan. With the continued role of satellites such as the Beidou navigation system, the output value of this industry in China is expected to grow to 62 billion yuan by 2020.

On January 12, Zhang Yimou praised Zhao Liying in an interview, and broke the news at the scene that Zhao Liying did not talk to others in the crew, just to find the status of the character. Zhao Liying also said that this was a very difficult challenge. She would put on earplugs on the scene and try to put herself into the character. If everyone communicated with her in sign language, she would succeed.

　　Xinhua News Agency, Beijing, October 10th, by topicFive-hundred-meter Aperture Spherical Radio Telescope (FAST) opened his eyes and saw two pulsars. What will he find in the future?

　　Xinhua News Agency "Xinhua Viewpoint" reporter Dong Ruifeng and Qi Jian

　　4,100 light years, 16,000 light years. Five-hundred-meter Aperture Spherical Radio Telescope (FAST), located in the mountains of Guizhou, just opened its eyes and saw two pulsars so far away from the earth.

　　On the 10th, the National Astronomical Observatory of Chinese Academy of Sciences announced that after a year of intense debugging, the 500-meter spherical radio telescope (FAST) has realized the smooth operation of various observation modes such as pointing, tracking and drift scanning, and confirmed several newly discovered pulsars.

　　The pulsar family has the "China Star" for the first time.

　　This is the first time that China’s astronomical equipment has discovered pulsars and achieved a "zero breakthrough" in this field. Since the first pulsar was discovered in 1967, there have been at least 2,700 members of the pulsar family discovered by humans in the past 50 years.

　　The National Astronomical Observatory announced the specific information of these two pulsars: the former has a rotation period of 1.83 seconds, which is about 16,000 light years away from the Earth, and the latter has a rotation period of 0.59 seconds, which is about 4,100 light years away from the Earth. It was discovered by Five-hundred-meter Aperture Spherical Radio Telescope (FAST) on August 22 and 25 this year in galactic plane, South China.

　　This is only part of Five-hundred-meter Aperture Spherical Radio Telescope (FAST)’s discovery. Li Yong, deputy chief engineer of "Tianyan" project, said that the debugging progress of "Tianyan" has exceeded expectations. At present, dozens of high-quality pulsar candidates have been detected, of which 6 have passed international certification.

　　According to scientists, pulsar is a neutron star with high speed rotation, which is produced by star evolution and supernova explosion. Its density is extremely high, weighing hundreds of millions of tons per cubic centimeter, and the size of a cube of sugar is equivalent to the weight of 10 thousand tons of ships on the earth. Pulsar is the most accurate clock in the universe because of its fast rotation speed and accurate rotation period. Because of this, pulsars emit intermittent periodic pulse signals, just like a rotating lighthouse that emits flickering light.

　　This special "skill" makes pulsars have important applications in the fields of timing, gravitational wave detection, and general relativity testing. Li Yong said that pulsars have extreme physical properties that cannot be realized in ground laboratories, and studying them is expected to get answers to many major physical problems. For example, the rotation period of pulsars is extremely stable, and accurate clock signals provide an ideal tool for major scientific and technological applications such as gravitational wave detection and spacecraft navigation.

　　"By long-term monitoring of rapidly rotating radio pulsars and selecting a certain number of pulsars to form a timing array, we can detect low-frequency gravitational waves from celestial bodies such as supermassive double black holes." Li Wei said.

　　George Hobbs, scientific director of the Parkes telescope at the Australian Academy of Science and Industry, said that the debugging and gradual production of the "Eye of the Sky" is one of the most exciting events in the international astronomical community.

　　Debugging results in one year, comforting Nan Rendong, the "father of the Eye of the Sky"

　　The original idea of "Eye of the Sky" came from the late astronomer Nan Rendong. From the idea put forward in 1994 to the official opening in 2016, Nan Rendong and his team have been pushing this seemingly incredible world-class project with all their efforts for 22 years.

　　There is no precedent in design and structure, and the early debugging of "Eye of the Sky" encountered great difficulties. Wang Qiming, chief engineer of "Eye of the Sky" project, said that all systems focused on equipment tracking and maintenance at first, and the debugging in the system seemed to be all right. However, after the joint debugging of all systems, a series of problems such as communication between systems, algorithm unification and security coordination were gradually exposed.

　　During the joint debugging period, the working state of "Tianyan" people is basically to work separately during the day, concentrate on meetings at night, change procedures overnight, and then try new schemes the next day, and repeatedly adjust to the best. In the 380 days and nights after the completion of "Eye of the Sky", the main control room is always open 24 hours a day unless there is power failure. During the day, the engineering team and the construction personnel concentrate on debugging; At night, researchers will fix the surface shape so that it points to a specific sky area, and through the rotation of the earth, the sky will drift and scan over the telescope.

　　Li Yong said that the drift scanning method is rarely used in pulsar search, but it can only be used during debugging. For this reason, researchers not only need to redesign the software, but also have to pay more work in data processing, but the final result is exciting. "Eye of the Sky" can get one or two high-quality pulsar candidates every scan.

　　Peng bo, a researcher at the National Astronomical Observatory and deputy manager of the "Eye of the Sky" project, said that it usually takes three to five years to debug foreign similar large-scale radio telescopes, and the "Eye of the Sky" has achieved initial results after debugging for one year.

　　"Eye of the Sky" will look for "aliens" and will dominate the future cosmic sky map.

　　Chinese and foreign scientists are expecting the discovery of "Eye of the Sky" to change from quantitative change to qualitative change. If "Eye of the Sky" can be the first to capture pulsars of galaxies outside the river, it will be of groundbreaking significance. Li Yong and his research team are already making technical preparations for observing pulsars in extragalactic galaxies, and will try them as early as next year.

　　Jocelyn Bell, the first astronomer to discover pulsars, visited the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) earlier this year. She expected the world’s largest radio telescope to discover more faint, distant and unique pulsars, including those revolving around black holes.

　　For the "Eye of the Sky" whose observation range can reach the edge of the known universe, the discovery of pulsars is only one of its missions. In the future, it will also shine in neutral hydrogen observation, spectral line observation and finding possible interstellar communication signals.

　　According to BIGBANG’s theory, neutral hydrogen is an "old man" who is almost the same age as the Big Bang in the universe. Observing and studying the distribution of neutral hydrogen can help scientists to further understand the structure of the Milky Way and extragalactic galaxies and solve the mystery of the origin and evolution of BIGBANG and other universes. "Five-hundred-meter Aperture Spherical Radio Telescope (FAST) will draw the latest and largest standard cosmic sky map by patrolling the neutral hydrogen in the universe." Marko Krco (Kyle), a senior postdoctoral fellow in the "Eye of the Sky" project of the National Astronomical Observatory, said.

　　"Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" can even "monitor" the radio waves emitted by alien civilizations that may exist in the universe. George Hobbs, scientific director of the Parkes telescope at the Australian Academy of Science and Industry, said that 20% of the time of the Parkes telescope is currently allocated to "looking for aliens", but nothing has been found. "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" has seen further, and maybe there will be exciting news in the future.
