　　On October 28th, after completing the related work in the technical area at Wenchang launch site in Hainan, China’s largest new generation launch vehicle Long March 5, which carried out its mission for the first time, was successfully transported vertically to the launch area, and it is planned to launch it at the beginning of November.

　　The Long March 5 carrier rocket developed by China Aerospace Science and Technology Corporation is a new generation of large-scale cryogenic liquid-bound carrier rocket in China. Its geosynchronous transfer orbit carrying capacity is 13 tons, and its near-earth orbit carrying capacity is 25 tons, which can be compared with large foreign rockets currently in service. Its main features are great strength, strong body, low cost, no pollution and more reliability … …

　　Why build the Long March 5?

　　At present, China’s conventional "Long March" series of launch vehicles have made remarkable achievements, and their reliability has reached the advanced level in the world, which can basically meet the transportation needs of China entering space.

　　However, since the 21st century, the world’s major space powers have launched a new generation of large-scale launch vehicles, such as Cosmos 5, Delta 4 and Ariane 5 in Europe. They not only have large thrust and the carrying capacity in low-earth orbit reaches 20 tons, but also use cheap, non-toxic and pollution-free low-temperature propellant.

　　Compared with similar foreign rockets, China’s mature rockets in active service still have a certain gap. For example, the carrying capacity is small; Most of them also use high-cost, toxic and polluting propellants.

　　In order to meet the needs of China’s major space engineering tasks in the future, especially the needs of space development in the next 20-30 years, and catch up with the advanced level of foreign new large-thrust launch vehicles, in October 2006, China began to develop the Long March 5 new generation large-scale launch vehicle. It has a series of new characteristics: large diameter, large thrust, few stages, serialization, low cost, high reliability, easy operation, no pollution, wide application and so on, and its carrying capacity is the same as that of foreign mainstream launch vehicles.

　　The Long March 5 all-arrow adopted 247 core key new technologies, and the proportion of new technologies reached almost 100%. In the international development of new rockets, including satellites and spacecraft, the proportion of adopting new technologies generally does not exceed 30%. In the past, the "Long March" rocket used tens of thousands of parts at most, while the Long March 5 rocket used hundreds of thousands of parts, and its design quantity was more than 3.5 times that of the previous "Long March" rocket.

　　According to the plan, in 2017, China will use the Long March 5 to launch the Chang ‘e-5 lunar sampling returner, in 2018, it will start to launch the 20-ton space station module one after another, and in 2020, it will launch the first Mars probe in China … …

　　Big physique, great strength and great difficulty

　　As a new generation of launch vehicle with the largest carrying capacity in China, Long March 5 integrates many latest space technologies. For example, the 5-meter-diameter arrow structure is adopted for the first time, and the non-toxic and pollution-free combined take-off scheme of liquid hydrogen/liquid oxygen and liquid oxygen/kerosene engine is used for the first time. Because of its large size, great strength and great difficulty, Long March 5 is also called "Big Rocket" for short, and it is the first heavy rocket in Asia at present.

　　The Long March 5 is equipped with three kinds of 12 new high-thrust cryogenic engines and sufficient fuel, so the power is very strong. Its take-off thrust exceeds 1,000 tons, which makes China’s ability to enter space more than 2.5 times, crossing the "threshold" of international large-scale launch vehicles with a low-orbit carrying capacity of 20 tons and a high-orbit carrying capacity of 10 tons, and some technical indicators still exceed those of the world’s major large rockets such as the United States and Europe.

　　Its core has a diameter of 5 meters and is bundled with four boosters with a diameter of 3.35 meters. Previously, the diameter of China’s rocket core was 3.35 meters, and the diameter of booster was 2.25 meters. Because the Long March 5 is thick, everyone affectionately calls it "Fat Five". Long March 5 was designed as a "big body" in order to accommodate more propellant and generate more thrust. This can also reduce the number of stages of the rocket, thus reducing the separation times of the rocket and improving the reliability and control ability of the rocket. This is the development trend of contemporary new high-thrust rockets.

　　In addition, the core engine of Long March 5 uses liquid hydrogen/liquid oxygen fuel, while the booster uses liquid oxygen/kerosene fuel. It is the first time in China that this combined take-off scheme uses two kinds of non-toxic and pollution-free low-temperature fuel engines at the same time. The reason why this complex combined takeoff scheme is adopted is that the working time of the first and second cores is long, so it is suitable to adopt the liquid hydrogen/liquid oxygen power system with high specific impulse; The working time of the booster is relatively short, so it is suitable to use the liquid oxygen/kerosene power system with large thrust and high propellant density to increase the specific impulse of the engine. By adopting this scheme, the rocket scale is the smallest and the number of engines used is the least, thus effectively improving the carrying capacity and efficiency.

　　It is the first time in the development history of China’s launch vehicle that all its core stages use low-temperature propellant. Because the temperature of liquid hydrogen is -253℃ and liquid oxygen is -183℃, the interior of Long March 5 is extremely low temperature far below the freezing point, which is a veritable "ice arrow". Because its combustion produces water, the rocket is non-toxic and pollution-free, which also marks a new step in the reliability, safety, adaptability and environmental friendliness of the launch vehicle in China.

　　Change "carrying the burden" to "carrying the sedan chair"

　　The reason why Long March 5 achieved the international advancement of various performance indexes was that it broke through 12 major key technologies in an all-round way, including: structural design, manufacturing and testing technologies for large-scale arrow bodies with a diameter of 5 meters; 120-ton liquid oxygen/kerosene engine technology; 50-ton liquid oxygen/liquid hydrogen engine technology; 9-ton thrust liquid hydrogen/liquid oxygen engine technology; Rocking suppression technology of large cryogenic rocket: Low-temperature pressurized conveying system with circulating pre-cooling technology and new valve technology; Booster engine swing and front fulcrum force transfer attitude control technology of large liquid launch vehicle, etc. These are the major core key technologies encountered for the first time in the history of launch vehicle development in China, and they are also difficult problems in rocket development in the world.

　　In addition, it has broken through many other technologies, for example, its vertical transshipment technology is extraordinary. Because the Long March 5 rocket is about 57 meters long, equivalent to 20 stories high, and weighs more than 600 tons, it was "walked" on the 2800-meter seamless rail for about 2 hours with a movable launching platform half the size of a football field, that is, its vertical transfer speed did not exceed 30 meters per minute. Along the way, the mobile launch platform not only carries the Long March 5 rocket, but also supplies gas and power for the rocket. In this way, the connection between the rocket and the ground can be kept unchanged during the transition of the rocket, thus reducing the work in the launch area and shortening the launch process.

　　In the transition method, it is also very different from the active rocket. Other rockets are "shouldering the burden", and the Long March 5 rocket is "lifting the sedan chair" to "walk" more stably. What does this mean? In the vertical transition of the rocket, there are four support arms at the "foot" of the active rocket core level, which are used to let the rocket "stand" on the "car" steadily. The rocket booster is "carried" and "walked" by the core level, so it is called "carrying the burden". The Long March 5 rocket has 12 support arms during the transition, but they are evenly distributed at the "feet" of the four boosters, so the four boosters "lift" the core level, so it is very similar to "lift the sedan chair". Its transition can reach 8-9 winds, and there is no need for any wind-proof and load-shedding device in the middle. The successful completion of vertical transshipment marks that the first flight mission of the Long March 5 carrier rocket officially entered the launch stage.

　　Can be combined like building blocks.

　　On the basis of extensive and in-depth analysis and research on the latest launch vehicle technology and future development trend in the world, China’s Long March 5 series launch vehicle adopted the general idea of "one series, two engines and three modules" and implemented the design principle of "generalization, combination and serialization". Different combinations of the three modules and the core stage can form six configurations of a new generation of large-scale launch vehicles with a core stage diameter of 5 meters, and a new generation of medium-sized and small-sized launch vehicles can be derived from the new generation of large-scale launch vehicles. Using modular design idea can realize technology sharing, improve reliability, save cost and shorten development cycle.

　　The basic model of Long March 5 is a two-stage semi-rocket with booster, with a total length of 57 meters. Its take-off mass is 878 tons, take-off thrust is 1078 tons, and the carrying capacity of geosynchronous transfer orbit is 14 tons, which is used to launch the Chang ‘e-5 lunar sampling returner.

　　The Long March 5 B rocket dropped the second stage on the basis of Long March 5, which was used to launch the cabin of China’s 20-ton space station. This one-and-a-half-stage rocket with booster has a total length of 53.7 meters, a take-off weight of 837.5 tons, a take-off thrust of 1,078 tons, and a low-earth orbit carrying capacity of more than 22 tons.

　　Long March 5/Expedition 2 is a three-stage rocket with booster. Based on the basic model of Long March 5, it added the upper stage of Expedition 2 as the third stage. It mainly performs launching tasks such as large-scale geostationary orbit and circular orbit in Beidou navigation. The Long March 5, which was first launched this time, is this model.

　　Extended reading

　　Why launch near the coast?

　　High-thrust rocket is the first prerequisite for completing major aerospace engineering tasks such as building a manned space station and deep space exploration, and it is also a necessary condition for human beings to return to the moon and land on Mars. However, the diameter of large thrust rockets is very large. For the three launch sites in China, transporting large rockets has always been a difficult problem, because when the diameter exceeds 3.5 meters, the trains transporting rockets cannot pass through culverts.

　　The Long March 5 series carrier rockets have a diameter of 5 meters, so they cannot be transported to three inland launch sites in China by train. Wenchang Satellite Launch Center is located near the coast of Hainan, and has a good port where ships carrying large rockets can be parked. This is the most important reason for launching the Long March 5 carrier rocket in Wenchang, Hainan. It adopts road-sea-road transportation mode, and the Long March 5 carrier rocket is transported from Tianjin to Hainan by two special transport ships. China’s future heavy-duty launch vehicle is about 10 meters in diameter, so it is likely to be launched in Wenchang, Hainan.

　　　　　　　 On August 19, John Woo’s first martial arts masterpiece "Sword Rain", which was invested by Beijing Pony Pentium Film Co., Ltd. for 14 million US dollars, officially launched its official website in Beijing Fortune Shopping Center and exposed the posters of the constellation of stars. "Sword Rain", which will be released nationwide on September 28, is known as "a movie without supporting roles". It is the strongest lineup of Chinese martial arts that gathers Yang Ziqiong, Zheng Yusheng, Wang Xueqi, Da S, Yu Wenle, Lin Xilei, Dai Liren, Bao Qijing, Wu Peici, Guo Xiaodong, Li Zonghan, Jiang Yiyan and other 12 A-list stars, together with Su Zhaobin, Dong Wei, Jin Peida, Hetian Huimei and other ultra-luxury teams behind the scenes. For this reason, the film broke the conventional poster design and specially tailored the constellation posters for the twelve starring characters. Each star’s character in the play corresponds to a constellation, and the famous constellation Little Prince writes the constellation judgment, and the "star luck" reveals the fate of the characters in the play.

　　　　　　　 "Rain of Swords", with the theme of a retired female killer being hunted by a killer group, was called a martial arts version of the "killing game" by John Woo. The story tells that after the female killer "Zeng Jing" (Yang Ziqiong) washes her hands in a golden basin, she becomes a couple with the simple young messenger "Jiang Ah Sheng" (Zheng Yusheng) in the small town, but because she has the holy things that everyone in the rivers and lakes desires, she cannot escape the hunting and killing of the killer group (Big S, Yu Wenle, Dai Liren, etc.) led by the "Wheel King" (Wang Xueqi). In the endless "killing game", she gradually drifts away from ordinary life and falls into the struggle of killing or redemption… Because of the ups and downs of the plot and the shocking picture, "Sword Rain" is known as "more entertaining, more literary, and more popular than". Woo, who has always been known for depicting men’s friendship, "abandoned" brotherly loyalty for the first time and praised the heroine in his first martial arts film. In an interview, Woo admitted that unlike his previous emphasis on brotherly chivalry, in "Sword Rain" with women as the protagonist, love will be an important element. "" Sword Rain "is not a simple fight to kill, revenge, it actually tells a love story between men and women, it is a humanized movie."

　　　　　　　 At the press conference, the calligraphy font of the title of "Jian Rain" was first announced. The global collection of calligraphy fonts jointly initiated by the producers of "Jian Rain" and the "2nd" Chen Xiang Four Forces "Zero Basic Calligraphy Crash World Internet Protocol Television Selection Committee" received more than 10,000 works from home and abroad. In the end, Shen Congqi, the inventor of the "father of the saber" in New China, won the prize, and his written title was officially used in the film title.

　　　　　　　 Although "Sword Rain" is a female hero film led by "female version of Chow Yun-fat" Yeoh Michelle Yeoh, the "female hero" was absent on the day of the launch. Under the leadership of Woo, Wang Xueqi, Yu Wenle, Dai Liren, Guo Xiaodong and Li Zonghan were generous to help out. Woo joked that "this is the biggest suspense of the movie". Among them, the combination of "killer trio" Wang Xueqi, Yu Wenle and Dai Liren became the biggest highlight, and they showed their respective lore tricks – eyes, smiles and unique weapons.

Constellation posters have less murderous intent and more laughter? John Woo: "’Sword Rain’ is against being superior"

　　　　　　　 Unlike previous movie posters, "Sword Rain", known as "no supporting movie", has a strong lineup and a collection of stars. The film deliberately broke through the traditional star poster design method and tailor-made constellation posters for the twelve starring stars. Each star corresponds to a constellation, and invited famous constellation experts to write constellation judgments to reveal the characters’ characters and fates with "star luck". In the previously exposed female version of the series of posters, online popular words such as "embarrassing mother-in-law" and "sharp sister" frequently appeared in the character judgments, causing controversy among netizens. The male version of the poster exposed on the day of the press conference still contained buzzwords such as "Octopus Emperor" and "Low Carbon Senior Monk". The poster of the character played by Guo Xiaodong directly quoted "My life can be copied", reminiscent of the "Tang Junmen" that was popular a while ago.

　　　　　　　 As a martial arts blockbuster with a strong lineup in front of and behind the scenes, "Sword Rain", which is known as the martial arts version of the "killing game", is the use of many entertainment words in the poster "insufficient murderous"? In this regard, John Woo said that "Octopus Emperor", "Sharp Sister", "Embarrassed Granny", in fact, behind every seemingly entertaining interpretation actually contains an interpretation of the fate of the characters, and the audience will naturally understand the reason for the words after watching the movie. At the same time, John Woo is personally disgusted with high-flying martial arts films. "The story of" Sword Rain "itself hopes to make the audience feel realistic and identified." He suggested that everyone might as well take a seat in their respective constellations with the mentality of the game and really join this "killing game".

"Killer trio" kills without a sword, Wang Xueqi: "Lust is not animal nature, it is human nature"

　　　　　　　 Despite the collective absence of "female heroes" such as Michelle Yeoh and Big S, the collective appearance of the male heroes on the scene is still imposing, especially the "killer trio" composed of Wang Xueqi, Yu Wenle and Dai Liren. In the play, they are the main characters of the "Blackstone" killer group that pursues and kills Yang Ziqiong. It is their step-by-step hunting that brings urgent suspense to the film. The screen images are mostly Wang Xueqi, Yu Wenle and Dai Liren, who appear in the front. For "Sword Rain" to break the limit and play bad guys, and each finds the secret to quickly increase the murderous aura – eyes, smiles and strange weapons. Wu Yusen introduced that "killers are not necessarily cold-blooded, and sometimes the killing with a smile is more lethal."

　　　　　　　 In addition, Wang Xueqi, who plays the villain No. 1 and the head of the killer group "The Wheel King", "protested" at the press conference that the verdict in his poster was "bestial and inhumane." He said that his villain in the play is not an absolute bad guy who is inhumane. "Whether it is the change of character identity before and after, or his personal unremitting pursuit, I believe that in the end, the audience will feel that he is very worthy of sympathy." And the erotic drama in the movie that has been hyped up before does not mean that it is "bestial." "The erotic drama in the movie is paved with literary drama, not naked wrestling and beating the shoulders when you come up. And when we shoot, we also strive to act more beautifully, better, and more suitable for people’s emotions, so that people can feel the beautiful enjoyment in lust. "

　　Xinhua News Agency, Beijing, September 14th (global hotspot) Russia-Belarus military exercise NATO tension

　　Xinhua news agency reporter

　　The "West-2017" joint military exercise between Russia and Belarus was unveiled on the 14th. Although the Russian side has repeatedly said that this military exercise is "purely defensive in nature", NATO has been nervous.

　　News fact

　　The exercise lasted until 20th. The exercise venue started from kola peninsula, Russia, and went all the way to Belarus. The theme was to train the armed forces to ensure the military security of the Russian-Belarusian alliance countries. The main purpose was to optimize the operational compatibility of the general staff of the two countries at all levels, and to connect the two countries’ armies and weapons command systems.

　　Today, the Russian news agency reported that the number of soldiers participating in this event reached 12,700, and about 70 military aircraft, 250 tanks, 200 artillery pieces and 10 warships were used. Russian Defense Minister shoigu said that this exercise is "the most important armed training this year".

　　Russia and Belarus have close relations. At the end of 1999, the two countries signed a treaty to establish a Russian-Belarusian union country, and they are committed to forming a confederate country while retaining their respective national sovereignty. The two countries held joint military exercises in Belarus for the first time in 2009, and then held such joint military exercises in turn every two years.

　　Belokonev, First Deputy Minister of Defense and Chief of Staff of the Armed Forces of Belarus, said that the military exercise was defensive in nature. NATO has continuously increased its military deployment in the three Baltic countries and Poland, and frequently approached the white border area. It is against this background that the "West-2017" exercise was carried out.

　　[Depth analysis]

　　Both Russia and Belarus stressed that this military exercise will not pose any threat to Europe as a whole or neighboring countries, but the relevant news has caused tension among NATO countries since its release. Western public opinion’s speculation about the actual scale of the Russian-Belarusian military exercise and the intention behind it is even more rampant. German Defense Minister Ursula von der Leyen recently said that the actual number of soldiers participating in the military exercise was as high as 100,000, and the exercise was intended to be "strategic intimidation".

　　The reason why this military exercise caused anxiety in the west is inseparable from the recent deterioration of relations between Russia and the United States and other western countries. Not long ago, some Russian diplomatic facilities in the United States were closed, and the US military’s military deployment against Russia in Europe was also increasing, and the relations between the two countries were in trouble.

　　Analysts believe that in the context of such a large-scale military exercise, the relationship between Russia and the West cannot be eased, and mutual distrust and hostility may intensify. NATO may take countermeasures, but both sides will not let things get out of control.

　　[First Comment]

　　Military exercises in peacetime are a good opportunity to test the combat effectiveness of the army and enhance its combat capability. For Russia, it is a good opportunity to enhance its deterrence against NATO. The Russian-Belarusian joint military exercise has had a wide impact before it started. It can be said that Russia’s purpose has reached half.

　　NATO’s eastward expansion and the United States’ military deployment in Eastern European countries have always been regarded by Russia as a major hidden danger to its national security, and it is also a deadlock of mutual distrust between Russia and the West. After the Ukrainian crisis, the United States and NATO countries frequently held large-scale military exercises in Eastern Europe, the Black Sea and the Baltic Sea, constantly challenging Russia’s bottom line. Russia also urgently needs to shock the other side through similar means to show its military strength in order to maintain the geopolitical balance of power in this region. Although it is helpless, it is also reasonable.

　　[Background link]

　　According to Russian media reports, the "Western" series of military exercises was inherited from the Soviet Union. At that time, it was a large-scale strategic military exercise held by the Soviet Union in the western border area with more weapons and equipment. In 1999, after NATO air strikes against Yugoslavia, Russia resumed this series of military exercises.

　　The "Western" series of military exercises held under the framework of Russia-Belarus Union countries began in 2009, and it is the largest among the military exercises held between Russia-Belarus Union countries. Russian official news shows that this series of military exercises is held every two years.

　　The background of the "Western-2017" joint military exercise superimposed on the Ukrainian crisis and the deterioration of relations between Russia, Europe and Russia and the United States is even more interesting. (Reporter Wang Moying, Zhao Yan, editor Liang Yan, Wang Fengfeng)

　　Russian Deputy Defense Minister: The "West-2017" military exercise is not an excuse for NATO to deploy troops on the Russian border.

According to the data released by National Health Commission, as of April 3rd, 136.677 million doses of Covid-19 vaccine were reported in all localities.

At present, five Covid-19 vaccines have been approved for use in China. What’s the difference between these five vaccines? Which variety is better? The expert responded.

According to the technical route, the five vaccines are divided into three categories:

One is inactivated vaccine, includeSinopharm Zhongsheng Beijing Company, Sinopharm Zhongsheng Wuhan Company and Beijing Kexing Zhongwei Company. Three inactivated vaccines produced;

The second is adenovirus vector vaccine, forTianjin kangxinuo company Production of adenovirus type 5 vector vaccine;

The third is recombinant protein vaccine, forRecombinant novel coronavirus vaccine (CHO cells).

What is the difference between the three technical routes?

"Inactivated vaccine is a vaccine prepared by a series of purification techniques after the live virus is killed by physical and chemical methods." Wang Junzhi, deputy head of the expert group of the vaccine research and development special class of the State Council Joint Prevention and Control Mechanism and academician of China Academy of Engineering, said that its main feature is that the composition of the vaccine is similar to that of the natural virus, and its immune response is strong, so it has good safety.The vaccine is relatively stable, can be stored at 2-8 degrees Celsius for two to three years, and is convenient to transport; Take two injections of immunization.

"Adenovirus vector vaccine is a live vector vaccine made by taking adenovirus type 5 as a vector, introducing Covid-19 antigen gene and making it through bioreactor." Wang Junzhi said that the vaccine preparation process is relatively simple, and the research and development costs and production costs are relatively low, because it was successfully developed on the basis of the original platform of Ebola vaccine for adenovirus type 5 in our country.Vaccine can induce antibody production and enhance cellular immunity; You can take a single needle immunization.

"Recombinant protein vaccine is to express the most effective antigen components in vitro by genetic engineering. In vitro cells are cells commonly used by engineering cell lines in biological products, similar to industrial fermentation, and finally made into vaccines. " Yan Jinghua, a researcher at the Institute of Microbiology, Chinese Academy of Sciences, said that the whole production process is a process of protein expression and purification, and there is no live virus involved, so the production process is safe and easy for mass production. From the past use process of recombinant protein vaccine and the previous experimental results, the safety of recombinant protein vaccine can be guaranteed, and the adverse reaction rate is relatively low.The vaccine is refrigerated at 2-8 degrees Celsius, which has low requirements for transportation and storage conditions; Take two or three injections of immunization.

Which vaccine is more effective?

Wang Junzhi said that the three routes of Covid-19 vaccine have their own characteristics. No matter what technical route is adopted, the most important thing is to develop a safe, effective and quality-controlled vaccine by combining the characteristics of antigen and pathogen, which is the key criterion for vaccine success.

He Qinghua, a first-class inspector of National Health Commission CDC, said that at present, all Covid-19 vaccines listed in China have been examined and approved by the drug regulatory authorities.Its safety and effectiveness are supported by certain data, so you can safely inoculate.

How to choose single needle and double needle?

Shao Yiming, a researcher at China CDC, introduced,For people who need to go to epidemic areas for temporary or urgent tasks, but don’t have enough time to wait, it is more suitable to inject single-needle adenovirus vector vaccine. In addition, single-needle inoculation can avoid the poor immune effect caused by failure to get the second needle for various reasons.

Single-needle vaccine also has shortcomings. Shao Yiming suggested that the immune response intensity induced by single-needle adenovirus vector vaccine is generally weaker than that induced by two-needle vaccine, and it is no problem in preventing early epidemic virus. When it is replaced by late mutant virus, the protection efficiency will mostly decrease. Therefore, when choosing a vaccine, we should make a comprehensive judgment and scientific decision according to the specific situation of the people to be protected and the latest monitoring data of local epidemic viruses.

Why is vaccination first for young people and then for the elderly?

According to an interview with Dr. Zhang Wenhong from CCTV News: ① The elderly are less socially active than young people and may not be easily infected; ② The main task of epidemic prevention and control in China is to prevent external import and internal rebound, and most people who are exposed to viruses, such as doctors, are young people; ③ The incidence of other diseases in the elderly population is high, which needs more clinical research data to support.

I don’t have to fight when everyone else has?

Wen Yumei, an academician of China Academy of Engineering and a professor at Shanghai Medical College of Fudan University, said that vaccine is the only weapon that can completely control an infectious disease. Vaccination not only protects individuals from the pathogens of infectious diseases, but also limits the spread of pathogenic microorganisms in groups.

She pointed out that it is a good time to get COVID-19 vaccine. Because there is no epidemic in China, and most people are in good health, vaccination can protect everyone well. "We should take precautions and protect ourselves first."

In view of the mentality of some people that "I don’t need to get vaccinated when everyone else has finished", Wen Yumei said that this is a misunderstanding. The immune barrier formed by the population (generally about 70% to 80% people need to be vaccinated according to the Covid-19 transmission coefficient) can effectively control the spread of the epidemic, but it does not mean that individuals will not be infected. "Others are vaccinated because others are protected. If you are not vaccinated, you still have the risk of being infected."

Reminder: Don’t believe this message.

Recently, people across the country received a short message signed "Center for Disease Control", saying that "COVID-19 vaccine can be vaccinated by appointment" and attached an appointment link.

At first glance, it looks realistic, but you can see the flaw if you look closely. Yes, this is a scam message. If you receive a similar message, don’t believe it! Please delete it at the first time, don’t click on the link inside, and don’t fill in personal information.

One month after listing, there are more than 20,000 sets. At the same time, Tony Leung Chiu Wai, a Chinese-speaking film actor who won the Golden Award, Golden Horse Award and Golden Rooster Award, speaks for himself. It can be said that the price of 300,800 ~ 400,800 yuan will give you a car from the future, the avant-garde value of science fiction, and the leading intelligent technology of Yaoyao. Who doesn’t love such products?

Aouita 12 adopts a large hatchback without a side cabin. When we first saw it, we were shocked by its sci-fi sense. The warm and full front of the car is full of science and technology in fashion. The E-shaped split front family design is continued, but the proportion of Aouita 12 looks more harmonious than that of Aouita 11. The posture of Aouita 12 is the same, and the understanding of luxury coupe is somewhat similar.

As a luxury coupe, the body length of Aouita 12 has reached 5020mm and the car height has reached 1450 mm. The very low-lying posture directly tells us that this is a luxury coupe, and it also brings a good room rate to the interior space. In addition, the large slip back at the rear of the car and the 21-inch wheel hub also enhance the fashionable and smart atmosphere of the Aouita 12 side. The design of low front and high back makes the side of the Aouita 12 look like a GT.

All-LED Star-Travel Curvature Lamp Group shows avant-garde modeling, and its elegant taste is obvious. In addition, the vehicle is also equipped with an intelligent active air intake grille, which can be automatically opened and closed, allowing the driver to walk while driving.

In front of the windshield, there is the signboard screen of Aouita, which contains 10,500 light beads. After OTA, it can display rich scene modes, with high playability, such as yielding to pedestrians and temporary parking. When the vehicle is charging, it can display rich bubble animation interaction, and can also see the current power on the HALO screen.

The whole rear design of Aouita 12 is simple but not simple, showing a tough style, and the tail outline depicted by lines is full of strength, as if to tell people that it has strong performance potential. Above the rear of the car, Aouita 12 is equipped with a hidden active lifting tail, which constantly shows you that it is a performance coupe, which not only makes it look cooler, but also provides effective underground pressure for the vehicle at high speed, making driving more stable and safe.

Aouita 12 is the first model equipped with electronic rearview mirror in China. As for the electronic rearview mirror, the official claims that the view range is wider than the traditional rearview mirror, and the view of the rearview mirror will not be affected in extreme weather. It’s still very good to use on daily roads. No matter where your eyes are, you can easily see the situation on both sides of the car, which is both an advantage and a disadvantage. Physical rearview mirrors can gain a wider field of vision by moving the position of your eyes, but the visual range of electronic rearview mirrors is unchanged, especially when the sun is strong. The display screen of electronic rearview mirrors in cars is not clearer than that of physical rearview mirrors.

The most maddening thing about the electronic rearview mirror is that it is difficult for you to grasp the distance between the vehicle and the obstacles on both sides during parking. Even the 10-year-old driver failed to adapt to the Aouita 12′ s parking after a three-day test drive. Of course, the employees of Aouita Sales Center can’t easily park their cars by using the rear view mirror. As for the electronic rearview mirror, everyone can park their cars directly when they test drive, and they will know that it is worthwhile to spend this money.

As a luxury coupe, Aouita 12 has adopted a brand-new interior style design, with a 35.4-inch 4K panoramic huge widescreen and a large central control screen. With the steering wheel design of the special-shaped steering wheel, it has a rich scientific and technological atmosphere and a great sense of the future. At the same time, a large number of leather material packages, dual 50W liftable wireless fast charging, dual zero-gravity seats, seat massage ventilation and heating, and intelligent photochromism front windshield+panoramic canopy, etc.

Aouita 12 is the first intelligent electric vehicle adopting HarmonyOS 4.0 system in China. Its standard three-laser radar and Huawei ADS 2.0 advanced intelligent driving technology show a high level of intelligence. According to the official introduction, Aouita 12′ s intelligent driving experience is advanced, thanks to its actuator consisting of 3 lasers and 29 intelligent sensing hardware, with higher specifications, which makes the overall intelligence level by going up one flight of stairs.

Aouita 12 adopts front double wishbone and rear multi-link independent suspension, and is equipped with air suspension system and CDC dynamic suspension damping control, using ZF CDC electronically controlled shock absorber. Air suspension can reduce the height of the car body by up to 20mm and increase it by up to 25mm, thus ensuring the passability of vehicles. The normal driving in urban areas is very comfortable, the chassis is full of toughness, excellent in filtering fine bumps, strong in driving support when running mountains, stable in body posture, confident in cornering and able to have both comfort and sports!

Based on the advanced CHN platform, Aouita 12 has excellent basic performance, and the four-wheel drive accelerates for 3.9 seconds. The new car provides a 700km rear-drive endurance version and a 650km four-wheel drive endurance version under CLTC condition. The battery is provided by Contemporary Amperex Technology Co., Limited, and it is built on a full-stack 750V high-voltage platform, which supports the maximum overcharge of 240kW and can be charged from 0% to 80% within half an hour. The energy consumption of commuting test drive in urban areas is about 17.5kWh per 100 kilometers. Equipped with a 94.5-degree CTP battery pack, CLTC has a pure battery life of 700km, supports 750V high-voltage charging, and can fully charge 90% in 20 minutes by using the overcharged pile, which is still remarkable.

Behind Aouita, security is the virtue. Relying on the respective advantages of Changan Automobile, Huawei and Contemporary Amperex Technology Co., Limited, Aouita 12 has a good face value and is equipped with Huawei ADS 2.0 advanced intelligent driving system, which is first-class in many aspects. It is indeed a very good car with many highlights, but this sci-fi design may be more picky, and people who like it will like it very much, but some people think that the design is a bit advanced.
