In order to maintain consistency, we set the speed of elk test at 72km/h, and locked it with speed limit function to maintain accuracy. From the subjective driving experience, there is not much difference in the overall driving experience of the chassis with and without the installation of the rear anti-roll bar.

　　In the original factory state, the front reaction of the vehicle when it enters the B area from the A area is still rapid. However, when the anti-roll bar was tested after installation, the response speed of the rear was obviously improved, but there was no obvious sliding or oversteer, and the overall trend was still biased towards understeer, but the response speed of the rear was faster.

●Beijing Institute of Technology-Researcher’s Conclusion (Elk)

　　The main purpose of this test is to compare the influence of rear anti-roll bar on vehicle handling performance. Through the test vehicles before and after installing the anti-roll bar, the elk test was carried out respectively. Collect data such as vehicle roll angle and yaw angle, and then analyze the influence of anti-roll bar installation or not on vehicle emergency lane change.

　　Because of the uncertainties such as the stability of driver’s input, the condition of vehicle tires, and the ground conditions of the site, each group conducted three experiments and finally took the average value. Each experiment is based on the fact that no bucket is touched and the sensor signal is valid.

●CarSim simulation analysis

　　Because there are many variables in this test, it is impossible to ensure the consistency of each experiment strictly, so it is necessary to analyze the control variables with the help of simulation. Through CarSim software, it can be achieved that the control variables are only the anti-roll bar, driver input, vehicle state, ground and other influencing factors, and they are strictly consistent.

　　In CarSim model, the vehicle with the anti-roll bar removed and the vehicle with the anti-roll bar installed were respectively set up to carry out the elk test and predict the test results. According to the test vehicle parameters, the CarSim simulation model is set up.The simulation results are shown in the following two pictures. The first picture shows the change trend of vehicle roll angle before and after installing anti-roll bar, and the second picture shows the change trend of yaw angle before and after installing anti-roll bar. The red line is the vehicle without anti-roll bar, and the blue line is the vehicle with anti-roll bar.

　　Above (simulation and prediction of roll angle)It can be seen that the roll angle curves are different in amplitude and change rate.

　　The yaw rate in the above picture (yaw angle simulation prediction) remains completely consistent. To some extent, it can be considered that the change of roll angle can reflect the influence on vehicle handling performance before and after installing anti-roll bar, and the difference of yaw angle may be caused by many factors, such as driver input.Therefore, in the analysis of the measured data, we should focus on the roll angle.

●Analysis of vehicle roll angle related data (the following two figures)

　　Vehicle roll angle data is collected by GPS inertial guidance gyroscope. The positive value of the collected data means that the left side of the vehicle is lifted, and the negative value means that the right side of the vehicle is lifted. In the elk test, the roll angle curves of all six experiments before and after installing the rear anti-roll bar.

　　It can be seen from the figure that in a single elk test, the roll angle changed three times. For the first time, after the vehicle entered Zone A, the steering wheel turned left and input, causing the vehicle to lean to the right. After the second vehicle enters the B area, the steering wheel changes from left to right, which causes the vehicle to shift its center of gravity and lean to the left with a fluctuation. The third time the vehicle entered Area C, it tilted to the right again due to inertia.

● Elk test-peak of roll angle (below)

　　By comparing the maximum change of the third roll angle before and after installing the anti-roll bar, we can reflect the change of the roll degree of the vehicle with or without the anti-roll bar. Define the vehicle roll angle as peak 1 when it reaches the peak for the first time, peak 2 when it reaches the peak for the second time, and peak 3 when it reaches the peak for the third time, and take all peaks as absolute values. The average value of the peak values of vehicle roll angle before and after installing the anti-roll bar is shown in the following figure.

Low center of gravity transfer rate (below)

　　There is a shift of center of gravity in the process of vehicle emergency lane change. During the center of gravity shift, the vehicle will roll from one side to the other. When the suspension stroke is compressed or the center of gravity is transferred, the vehicle roll angle will not change. Therefore, the time between two peak values of vehicle roll angle and the time of roll angle fluctuation after the vehicle enters Zone B can reflect the vehicle center of gravity transfer rate. It is defined that the interval between the first and second peak values of vehicles is T1, the fluctuation time of rear inclination angle in area B is T2, and the interval between the last two peak values is T3. Before and after the installation of the anti-roll bar, the center of gravity transfer time is shown in the following figure.

● Elk test conclusion

　　The data of milu deer roll angle has widened the gap in the limit state, which is also the most obvious project at present. The center of gravity transfer rate is understood according to the basic principle (which side is harder, it will be smoother).There is basically not much difference in the speed of the first handlebar direction (T1), but with the increase of the inertia of the vehicle changing lanes, the two center of gravity transfer rates of (T2, T3) are both faster with the rear anti-roll bar, but the gap between them is not obvious.Generally speaking, the follow-up and overall feeling of the rear are better, but the overall limit and driving characteristics of the vehicle have not changed much.

　　Through the four-column road simulation test-bed, the road surface conditions of daily vehicles can be restored on the test-bed.The test-bed can realize stable road excitation, avoid the influence of traffic conditions, route selection and weather environment in the actual road test, and minimize the instability in the test.

　　In this experiment, the light cross-country road spectrum is selected as the bench excitation input, which can restore the situation of poor road surface in daily urban use environment. Record the change of the roll angle of the test vehicle during the experiment. (as shown in the figure below)

More exciting videos are all on the car home video platform.

● Bench test conclusion

　　It can be seen from the figure that the inclination curves of the anti-roll bars are different, but considering that the absolute values of the inclination angles are all below 0.5 degrees. In daily use, the feeling is almost not great, so to some extent, it can be considered that whether to install the rear anti-roll bar has no significant influence on daily use.

●Test summary of BMW 325Li (Beijing institute of technology-researcher)

●Objective data evaluation

　　In elk test, pile-winding test and track test, the installation of rear anti-roll bar has a positive impact on reducing the degree of vehicle roll, especially in elk test. At the same time, the installation of rear anti-roll bar has certain influence on the transfer rate of vehicle center of gravity, but the effect is not significant. The test data show that the installation of rear anti-roll bar has positive significance in vehicle attitude adjustment, but has no obvious effect on improving handling performance.

　　In the bench test, there are some differences in the change of roll angle, but they are all in a very low range. The bench test data show that the installation of rear anti-roll bar has no significant effect on daily driving.

●Subjective evaluation of testers

　　Testers on the vehicle can feel the somatosensory changes in the vehicle whether the rear anti-roll bar is installed or not during the test. Before the anti-roll bar is installed, the body shakes greatly, and the body feels lifted and thrown down in the steering process, which makes the vehicle feel more stable in driving. After the anti-roll bar is installed, the car body shaking is restrained to some extent, and there is no obvious difference in the lateral shaking of people in the car, which makes the tires slip more easily in the driving of the car.

　　In the process of testing, the tester outside the vehicle can observe the attitude change of the vehicle with naked eyes to a certain extent. Before installing the anti-roll bar, the vehicle shakes greatly, and the compression and rebound stroke of the suspension is longer when steering. After installing the anti-roll bar, there is a significant trend to reduce the body posture sway, which visually feels that the vehicle is more stable.

● Summary

　　　For long-wheelbase vehicles, after installing the rear anti-roll bar, the movement of the rear of the car has indeed changed, especially in the extreme driving state, which can directly perceive the change of the rear following. However, we can also see from the data that there is little improvement in performance, and daily use has no effect on comfort.

　　If you want to operate more directly and restore the function of the rear anti-roll bar, you can choose to install the original spare parts, but the overall improvement is not obvious. It is believed that the change of suspension performance will be more intuitive if it is replaced with the vibration isolator and adjusted in a targeted way.

　　Economic Daily-China Economic Net November 25 th During the 2020 Guangzhou Auto Show, Changan Auchan brought all its SUV models such as Changan Auchan X5 and Changan Auchan X7 to the Guangzhou Auto Show and opened two brand salons. He Chaobing, Executive Vice President of Changan Automobile/Chairman of Changan Auchan, Wang Xiaofei, General Manager of Changan Auchan and other leaders had in-depth communication with the media on brand positioning, strategic development and market performance of Changan Auchan. In addition, Changan Auchan also released a brand new brand Slogan—— in this salon-walking with a better life.

　　At the X7 listing conference of Changan Auchan held in the Great Hall of the People in Beijing in 2019, Changan Auchan gave its user group the title of "family-oriented enterprising family" for the first time. After Changan Auchan X7, Changan Auchan X5 and other fine models have won the favor of consumers and fully met their different needs, Changan Auchan extended its brand service from simple product communication to user links, and released a brand new brand slogan-walking with a better life and starting a new journey.

　　Just as Zhu Huarong, the chairman of Changan Automobile, put forward not long ago that "users will eventually choose the brands that choose users", Changan Auchan clearly takes "family-oriented enterprising people" as the target group, takes products as the anchor point, links users and brands, helps users pursue a better family life and helps them move forward together on the road to a better life.

　　From the perspective of brand attention, Changan Auchan has grown rapidly for three consecutive years from obscurity when it was first released in 2018 to the seventh level of its own brand in 2020, and has become a brand that users are proud of from a brand that is rarely mentioned.

　　　　Ruan Jingtian (right) suddenly kissed, which made Fan Yichen one of them "shocked", but the smile was very warm.

　　　　After Ruan Jingtian and Fan Yichen staged a scene of "Broken Back Kiss Ear", the two couldn’t help laughing.

　　　　Taiwanese men Ruan Jingtian and Fan Yichen went to Hong Kong the night before to promote the new film "Love to the End". Although Liu Xinyou and Makiyo participated in the performance with a sexy Party Look appearance, the two men suddenly made a "broken back kiss" to steal the spotlight, making Xiao Fan tremble and itch, and at the same time making the fans present shout and break their throats!

　　　　Ruan Jingtian and Fan Yichen, who quickly became popular in Hong Kong with the Taiwanese drama "I’m Destined to Love You" and the movie "Cape No. 7" respectively, recently took over the new film "Love to the End" funded by Xinghao Film Company. The two attended the "apm Christmas Magic Cabinet Tour" activity with "Love" actors Makiyo, Liu Xinyou, Ye Anting and Zhou Caishi the night before. The four beautiful girls wore evening clothes of different colors to match the Christmas theme. Among them, Makiyo was the most eye-catching. When playing the game, they kept leaning over and throwing 33D "Mimi" to show their beautiful figures.

　　　　Ruan Jingtian seemed unwilling to be robbed of the limelight, so he took the initiative to approach the fans to play selfies and autographs; when playing the dice game, Xiaotian also generously let the fans kiss their ears and chest, and finally gave a hug, coaxing the fans to scream excitedly! On the contrary, Fan Yichen appeared more passive and embarrassed. One of the female spectators just "kissed" his ear through the air, but Xiaotian couldn’t see it, that is, he naughtily "attacked" and really kissed Xiaofan’s ear, which made Xiaofan dumbfounded and didn’t understand the reaction. Afterwards, Xiaofan described the "broken back kiss" as feeling good, and he smiled and said, "This is a good one, very warm. In fact, being kissed by Fans feels very itchy, and I can kiss anywhere except my lips."

　　Makiyo love boyfriend Chanel bag

　　　　Xiao Tian said that he was very happy to be able to spend the festival with Fans, and asked if there was any place on his body that he couldn’t kiss? He smiled and said: "Recently, there have been a lot of kissing scenes, and if it is reasonable, it is acceptable. (Now it is very popular?) It is up to Chen Jon to bring Wang!" He bluntly said that every time he went to Hong Kong, he came and went in a hurry, hoping to shop secretly next time. When he asked if he would buy a gift for his girlfriend Xu Weining, he sold it off: "I won’t tell you!"

　　　　The sexy Makiyo also hopes to find time to shop. She said: "I have received a Chanel bag from my boyfriend for Christmas. I also bought a computer for him and will invite my friend Xiao S to dinner to celebrate." Zhou Cai Shi, on the other hand, mocked herself for having small breasts and dared not show off her low-cut clothes: "I am afraid of showing it to make people laugh." Liu Xinyou, who looks not very familiar with the other three actresses, explained: "Because everyone shoots separately, I don’t mind being robbed of the camera. Boys play games more prominently."

Fan Bingbing

　　Movie Network News(Photo/Qian Jia Yiwen/Xie Yawei) On December 14, "October Siege", which has a luxurious lineup of "Nine Emperors and One Queen" in the Chinese film industry, held a grand premiere in Beijing. Producers Chen Kexin, Huang Jianxin, director Chen Desen and starring Liming, Fan Bingbing, Li Yuchun, Liang Jiahui, Nicholas Tse, Hu Jun, Wang Xueqi, Zhou Yun, and Wang Baijie made a collective appearance for the film’s national release on December 18. At the press conference, Fan Bingbing was repeatedly harassed by media reporters, and he was once speechless and embarrassed, while Dawn, who was good at dealing with reporters, took the initiative to fight for Fan Bingbing. When facing the acerbic questions directed at him, he even exploded the thunder of "everyone is from the earth".

Fan Bingbing was embarrassed twice in the face of difficulties, saying that Li Jiaxin was the heroine

　　"The Queen of Topics" Fan Bingbing became the focus of media attention wherever she went. At the press conference, when the media asked her whether she had broken through the "vase" image in this "October Siege" performance, Fan Bingbing said twice in a row that she did not hear the question clearly, whether it was intentional or unintentional. When the question was repeated for the third time, she finally gave the most official answer, "I didn’t think about it that much, I just wanted to shape the character with my heart. In this film, I feel more of the dedication of everyone."

　　"October Siege" brings together the nine best actors in the Chinese film industry, which can be called a man’s play. Compared with the few female actors, the roles of several actresses are rare. Not long ago, after watching "October Siege", Mark Muller, the chairman of the Venice Film Festival, gave Zhou Yun a high evaluation, saying that "Zhou Yun supported the entire" October Siege ". When the reporter asked Fan Bingbing to express his opinion on this comment, Fan Bingbing, who has always been comfortable with the media, first smiled awkwardly, and then replied," I think a movie is not the power of one person, but the work of everyone’s hard work. Success is the result of everyone’s efforts. " Faced with the question of "who is the first heroine", Fan Bingbing immediately blurted out, "I think the real heroine is Li Jiaxin. My mother saw the film yesterday and said that her appearance was amazing." Although the reaction this time was very witty, Fan Bingbing could not hide his embarrassment and smiled unnaturally.

Liming stands up for Fan Bingbing, answers questions skillfully and then explodes thunder

　　Fan Bingbing had just been harassed by the media, and then Liming, who was on stage, was also asked the same question, "I never pay attention to the heroine’s problem, I only pay attention to the movie itself." Saying that, he also began to speak up for Fan Bingbing, "I think Fan Bingbing was quite miserable just now. He has been forced by reporters to ask such sharp questions, but it is just practice, and actors always have to face these questions. It is normal to ask such questions, but I am still surprised to keep asking them." The words made the atmosphere of the scene cold for a while.

　　Because Nicholas Tse said in the interview just now that he would take Cecilia Cheung and his son to watch "October Siege", and said that he would not worry about fetal gas, and joked that this film is suitable for all pregnant women to watch. When asked if he would take Leji to watch the movie together, Liming cleverly avoided the reporter’s intention to inquire about gossip, "Sorry, my wife is not pregnant yet, so I won’t take her to see it." Liming was one of the four kings of Hong Kong’s singing scene, but he did not sing the theme song of "October Siege", which would inevitably make some media inquire, and Liming broke out thunder again, causing a burst of laughter at the scene, "Li Yuchun, Tse Tse, they are all very good at singing, they can’t say that the king sings well. Everyone is from earth, and everyone is equal!"

Li Yuchun

Li Yuchun and Xiao Shenyang fight for popularity, Chen Kexin is not afraid of the "three guns" box office rhetoric

　　Li Yuchun was "electrocuted" for the first time in "October Siege", and some remarks said that "Li Yuchun can guarantee at least 50 million box office", while Li Yuchun was very modest, "This film has so many big names, I dare not say such words." In another New Year’s Eve film "Three Guns Shooting Surprise", Xiao Shenyang was called the biggest highlight. Li Yuchun confessed to the media about the popularity of the two. "I can’t answer this. I can only use numbers to explain the problem after the film is released."

　　Zhang Weiping, the producer of "Three Guns Shooting Surprise", made a bold statement in an interview not long ago, "This year’s New Year’s Eve, ‘Three Guns’ will be unstoppable!" And the promotional backboard of "October Siege" on the day of its premiere was also written "Unstoppable". When the media asked if the two films were secretly competing, Chen Kexin replied easily, "These are all propaganda slogans, don’t take them seriously." He said that now our country’s film industry is very prosperous, and it is not difficult for movies to break records at the box office. Nothing is impossible.

　　Among the vast stars, there are many stars with names, and the person who first discovered this star has the right to name it. In space, there is a star called "China Star", and its discoverer is a China — — Yuzhe Zhang. He was also the first director of the Purple Mountain Observatory after the founding of New China. Next, let’s meet this person from idolize.

　　In the middle of the night, the sky above the Xuyi Observatory of Purple Mountain Observatory is dotted with stars, which is the prime time for the NEO exploration and solar system celestial research team to carry out observation activities. Above the main control room, the largest NEO telescope in China is erected. Since the beginning of this year, the research team has discovered five asteroids and one comet with this "big eye", setting the best record in recent years.

　　Zhao Haibin, chief researcher of the Near-Earth Object Detection and Solar System Objects Research Group of Purple Mountain Observatory of China Academy of Sciences, said: "The name of this star we are seeing now is ‘ China Star ’ . Its international number is 3789. Actually, this ‘ China Star ’ We have often observed it recently. From August 2022 to January 2023, we observed this star 13 times. "

　　This "China Star" actually has another name. Yuzhe Zhang, who was studying in the United States in 1928, discovered this asteroid and named it "China Star". From "China Star" to "China Star", the change of the word difference is behind the tortuous experience of the development of modern astronomy in China.

　　In 1929, at the age of 27, Yuzhe Zhang completed his doctoral degree and returned to the Department of Physics of Central University to teach. At the same time, he served as a special researcher at the Institute of Astronomy of Academia Sinica. At that time, because there was no large astronomical telescope in China to track and observe, the "China Star" numbered 1125 was "missing" for a long time and lost its trace. In 1934, the Purple Mountain Observatory, which Yuzhe Zhang participated in the preparation, was finally completed. But before long, War of Resistance against Japanese Aggression broke out, and Yuzhe Zhang moved westward to Kunming with the Observatory. No matter how difficult the wartime conditions were, he did not give up astronomical research.

　　Wang Kechao, director of science popularization department of Purple Mountain Observatory of China Academy of Sciences, said: "On September 21st, 1941, there was a total solar eclipse in China. At that time, it was extremely difficult conditions in War of Resistance against Japanese Aggression. Yuzhe Zhang led a team to overcome all kinds of difficulties, set off from Kunming, Yunnan, and traveled 3000 kilometers to Lintao, Gansu, to make scientific observations on the total solar eclipse and successfully filmed a large number of precious total solar eclipse films. This is the first total solar eclipse photo taken by China people for the first time in their own country. "

　　After War of Resistance against Japanese Aggression, Yuzhe Zhang went to the United States again with the mission of learning the latest astronomical technology to prepare for the reconstruction of the Purple Mountain Observatory. After further study, Yuzhe Zhang declined to be retained by some astronomical institutions in the United States and resolutely returned to the motherland. He was appointed as the first director of the Purple Mountain Observatory after the founding of New China, and in the following 40 years, he created and led the observation and research work of planets, asteroids, comets and artificial satellites in China.

　　Wang Kechao said: "This reflective telescope with a diameter of 60 cm was the largest telescope in the Far East at that time. After returning to China, Mr Yuzhe Zhang repaired the telescope himself. It was next to this telescope that he led the young team through sleepless nights, discovering more than 100 new asteroids and 3 purple mountain comets. They have all obtained international permanent numbering and naming rights. "

　　Yuzhe Zhang also participated in the formulation of the national science and technology development plan, presided over the drawing of the blueprint for the development of astronomy in the 1960s, and made outstanding contributions to the aerospace and national defense of new China.

　　Zhao Haibin said, "He is one of the founders of modern astronomy in China. At the beginning, under the auspices of Mr. Yuzhe Zhang, I made a plan on how the astronomical community in China should develop. He presided over the design of the orbit determination scheme of the first artificial satellite in China, which actually plays a very important role in the launch orbit determination of our country’s Dongfanghong satellite. "

　　As if it were an invisible compliment, the asteroid 1125, which had been "missing" before, was observed many times in 1975, 1981 and 1986. In 1988, the International Committee on Asteroid Nomenclature decided to rename the asteroid 3789 and officially named it "China Star". From "China Star" to "China Star", Yuzhe Zhang’s lifelong love and persistence are just like starlight illuminating the future of Chinese astronomy.

　　Zhao Haibin said: "What our team is doing now is actually the same as what Mr. Zhang Lao is doing. More than 4,000 new solar system small objects have been discovered. In terms of data volume, we belong to the first echelon in the world, including the accuracy of observation data, and we have not lost face to Mr. Zhang. "

　　Gong Yizhong, a retired employee of Purple Mountain Observatory, said: "He lives a simple life and has very low requirements for his own treatment. At that time, the country provided him with a special car. He never took it, so he went up the mountain with us in a big open truck. The requirements for academic research are very strict, and it is absolutely not allowed to have academic falsehood or false data. We staff members have always kept it in our minds until now. "　

　　After 70 years, the former German binoculars were replaced by the NEO telescope independently developed by China people. Since 1956, the Purple Mountain Observatory has discovered nearly 5,000 asteroids. In 2006, the near-earth object telescope and Xuyi Observatory of Zijinshan Observatory were completed, and then seven field operational observation stations were set up in Qinghai and Antarctica. In 2015, Purple Mountain Observatory took the lead in developing and operating China’s first astronomical science satellite — — "Wukong" dark matter particle detection satellite; In 2022, Kuafu I, China’s first comprehensive solar exploration satellite, which was developed by Purple Mountain Observatory as the main unit, was successfully launched, opening a new era of comprehensive solar observation in China … … Along the road opened by the old director Yuzhe Zhang, generations of Zitai astronomers have been exploring the vast universe with a tough and rigorous scientific attitude!

The latest research report of Founder Securities believes that with the AITO M9 production capacity climbing, the sales proportion in the AITO brand continues to increase, driving the volume and price of Cyrus to double up. It is expected that the fastest is expected to achieve a turnaround in the profit contribution of the model in June 2024, and the profit cycle may start in the third quarter of 2024.

Turning on the air conditioner in summer is faster in terms of cooling effect, but if you are exposed to the sun, it is still recommended to cycle outside first.First of all, what’s the difference between internal and external circulation?

What’s the difference between internal and external circulation?

The quality of internal circulating air is good, but the oxygen content is low.

Internal circulation, it may lead to too high carbon dioxide, because the air intake is in the car. Simply put, the air outside can’t get in, and the air inside can’t get out.

After the internal circulation is turned on, the air is sucked in the car and filtered repeatedly by the filter in the air conditioner. The car with pm2.5 filtering function is equivalent to the role of an air purifier.

According to the measured data, the value of pm2.5 in open internal circulation is about 1/3 to 1/4 of that in external circulation. However, the current car sealing is relatively good, and long-term internal circulation is also problematic.

Low oxygen content will affect driving safety.

Generally, the interior space of a car is about 3 to 4 cubic meters. According to the larger one, an adult can breathe in a closed space of 4 cubic meters, and the carbon dioxide concentration can reach 1% in about 50 minutes.

The decrease of oxygen content makes people feel hot, tired and anxious. Anyway, it is uncomfortable, which actually affects driving safety.

For example, the air quality on the moon is good. Without pm2.5 and oxygen, people can’t stand your fresh air.

External circulating air has good circulation and high oxygen content.

Let’s talk about the external circulation, which is equivalent to sucking in the wind outside the car, usually under the windshield wiper, at the junction of the windshield and the hood.

To put it simply, the wind from the air outlet is sucked in from the outside of the car, which can ensure that the air inside the car is relatively circulated, so that the concentration of carbon dioxide is not too high or oxygen is not enough.

How to use internal and external circulation?

Conventional refrigeration, first open internal circulation and then external circulation.

According to the conventional refrigeration effect, it is better to open the internal circulation. When you drive out in the basement or garage in summer, the temperature of the car itself is not high. As soon as the internal circulation is opened, the hot air outside can’t enter, and the air inside is cooled by air conditioning as much as possible, the effect is the best.

You are like, staying in an air-conditioned room knows that the doors and windows should be closed tightly, or the air conditioner will run away. It is similar to turn on the air conditioner in the car. Internal circulation is equivalent to closing the doors and windows, which will make the cooling speed faster and the effect better.

As I said before, your internal circulation is on for too long, just like when your door is closed, it’s stuffy in the back, and your air has not been circulating, and the carbon dioxide is high and the oxygen is low.

Open the internal circulation for half an hour and then switch the external circulation.

Therefore, if the internal circulation is on for half an hour, the temperature is almost stable. I suggest you open the external circulation to let fresh oxygen in.

At present, more expensive cars have automatic adjustment function. In the first half hour, you pressed the inner loop, and later it will switch to the outer loop for you, which is more convenient. Then if it’s manual, you can press it yourself.

In the exposure environment, open the window first and then circulate outside.

However, the exposure environment is different. The temperature is actually very high when parked on the road. The School of Public Health of Nantong University sampled 100 cars and counted a data.

There are 60% of the air in cars, which exceeds the National Indoor Air Quality Standard. The formaldehyde concentration in each cubic meter is less than 0.1 mg, which is the standard and higher than this.

Exposure will double the formaldehyde concentration in the car.

Summer exposure, it will make the formaldehyde in the car emit at a faster speed and bake it out.

Looking for some data from other people’s experiments, you can make the original formaldehyde concentration of 0.16 mg per cubic meter rise to 0.33 mg per cubic meter, which is more than twice the air quality index.

Long-term exposure to formaldehyde, chronic respiratory diseases, induced cancer, anyway, everyone knows that formaldehyde is not good. So in this case, you should not only consider whether the temperature drops fast or not, but also consider whether the air quality inside the car is poisonous.

Open the window to allow air convection and reduce the concentration of formaldehyde.

Therefore, the formaldehyde concentration can be reduced from 0.27 mg/m to 0.09 mg/m by opening the window first and then circulating the air for five minutes.

You see, the drop is still quite a lot, from 0.27 to 0.09, which actually takes only five minutes. It is also a good choice to open the window first and then close it after five minutes.

The higher the temperature inside the car, the greater the load.

Another is that you are exposed to the sun. If the temperature is high, the load will be even greater. If you get a bad tan, the temperature inside the car may be sixty or seventy degrees Celsius, which some friends don’t know yet.

Your car will start the AC refrigeration button immediately, and the heat load it bears is still relatively large. It is possible to damage or three-way catalysis and reduce the service life of components, which is a small probability.

No matter how you say that you are cold and slow down, it will definitely have an impact. If you pour a glass of ice water into a glass of water at room temperature, the water at room temperature will get colder. If you pour a glass of ice water into a cup of hot water, it will be good to turn it into water at room temperature. That’s the truth.

"Spare tire says car" will give you a practical small dry goods every day, please pay attention to spare tire says car, 60 seconds a day, easy to understand.

　　The actions of actively bailing out real estate in various places are still going on. In addition to the deepening of urban policies, the actions of local governments to co-ordinate the deployment of Baojiao Building are gradually increasing.

　　On August 15th, Ma Yujun, Deputy Secretary of the Municipal Party Committee and Mayor of Shijiazhuang City, Hebei Province, investigated and inspected real estate projects and presided over a symposium on the stable and healthy development of the city’s real estate market. At least five real estate enterprises and two banks attended the meeting. Prior to this, Ningbo, Zhejiang, Hefei, Anhui, and Xianyang, Shaanxi also held similar forums for housing enterprises. One of the core contents of the meeting was "Baojiaolou".

　　Since July, some owners of "uncompleted residential flats" have cut off their supply and the data of the property market have continued to decline, and the market’s expectations for the real estate relief policy are getting stronger and stronger. After Politburo meeting of the Chinese Communist Party explicitly proposed to guarantee the delivery of the flats at the end of July and stressed the responsibility of compacting local governments, the pace of active relief in various places has also accelerated.

　　What did the housing enterprise symposium "talk about"?

　　At 9 o’clock on the evening of the 15th, WeChat official account’s WeChat "Shijiazhuang Release" under the Propaganda Department of Shijiazhuang Municipal Committee pushed an important message, which may be of particular concern to local citizens who bought faster houses.

　　The article shows that Ma Yujun investigated and inspected a number of real estate projects on the same day, including Yunshufu, Gaoying International, Heshifu, Changyue House, Spruce Valley, Zhongmei Covered Bridge, etc. Some of these projects are under construction, some are being sold to the outside world, and some are at a standstill.

　　After understanding the basic situation and construction progress of the project, Ma Yujun had an exchange discussion with relevant district governments, municipal departments and real estate enterprises, covering the existing problems, solutions and future development.

　　On the same day, Ma Yujun also hosted a symposium for real estate enterprises. The real estate enterprises that attended the meeting and made speeches included China Shipping Real Estate, MCC Mingguan, Hebei Poly Development, Shijiazhuang Vanke, and Rong Sheng, Hebei Province. The speeches mainly focused on the actual situation of each family and constructive suggestions for the healthy and orderly development of the real estate industry. In addition, the two participating banks also made speeches on real estate financial policies and related measures to support the stable and healthy development of the real estate market in the next step.

　　This is not the first city to hold a symposium on housing enterprises. Since July, several cities including Ningbo, Zhejiang, Hefei, Anhui and Xianyang, Shaanxi have held similar meetings. A big background of this phenomenon is that since the end of June and the beginning of July, the owners of "uncompleted residential flats" in many places across the country have jointly launched the action of stopping supply, hoping that those properties that have been suspended for a long time or temporarily can resume work and hand over the house as soon as possible.

　　On July 28th, Politburo meeting of the Chinese Communist Party also explicitly mentioned "ensuring the delivery of buildings and stabilizing people’s livelihood". On the basis of insisting on housing and not speculating, it emphasized the responsibility of compacting local governments and encouraged local governments to make full use of the policy toolbox because of the city’s policy.

　　Specifically, the host of local symposiums is mainly the Housing and Construction Bureau, and the main line of content is Baojiaolou.

　　For example, on July 19th, Xianyang Housing and Urban-Rural Development Bureau organized a collective interview meeting for some housing enterprises to urge them to strengthen their management, shoulder their social responsibilities, try to resolve conflicts, do a good job in prevention and early warning, plan ahead, and speed up the construction progress and strive to deliver the house on schedule while ensuring the quality and quantity of the projects under construction. At the same time, the meeting stressed that housing enterprises should take the initiative, not wait and rely, and try their best to solve the urgent needs of the masses.

　　On July 18th, the previous day, the Ningbo Housing and Construction Bureau also announced that recently, the Real Estate Market Supervision Department of the Bureau and the Housing Management Center convened six new Ningbo housing enterprises, including Weixing and Changzhu, to hold a symposium on real estate policy exchange and publicize the real estate industry policy.

　　At the meeting, Ningbo Housing and Urban-Rural Development Bureau, while interpreting and publicizing the relief policies such as pre-sale, full renovation, fund supervision and real estate regulation in the city, kept abreast of the investment plans and development progress of seven projects developed by six housing enterprises, and listened to the business conditions of various enterprises and suggestions for industry development.

　　Just recently, Hefei, Anhui received high attention because 17 real estate developers jointly wrote to the government, and then the government also held a special meeting, but the content was slightly "special".

　　In a Report on Solving Difficulties by Requesting to Maintain the Business Environment and Enhance the Investment Confidence of Housing Enterprises stamped with the official seals of 17 housing enterprises, 17 housing enterprises, including Longhu, Xuhui and Sunac, as well as Poly, Gezhouba and Greentown, collectively complained to the Hefei Municipal Government, saying that they were faced with some unreasonable group customer complaints and house troubles, and there may be professional house troubles behind them, so please ask the competent government departments to give them a hand.

　　On the morning of August 13th, Yu Aihua, member of the Standing Committee of Anhui Provincial Party Committee and secretary of Hefei Municipal Party Committee, presided over a special meeting on the governance of real estate problems in the whole city, stressing that we should not only attach great importance to the problems reflected by the masses, but also try our best to solve the problems encountered by enterprises and do everything possible to "ensure the delivery of buildings and stabilize people’s livelihood". For the unreasonable demands of a very small number of property buyers, it is necessary to strengthen communication, explanation, education and guidance. If there are violations of laws and regulations, they should also be dealt with according to the law. At the same time, it is said that developers, construction enterprises and supervision units should strengthen credit management and set up special classes to curb the occurrence of incremental problems.

　　Scheme: One-on-one guarantee of building delivery, strengthening supervision of pre-sale funds.

　　In the eyes of the industry, the discussion is only the first step to solve the problem, and a series of policies for Baojiaolou will be introduced in subsequent places. Especially when the macro-economy is under pressure and land revenue accounts for a large proportion of local finance, the pace of local government’s bail-out of housing enterprises will accelerate.

　　In fact, in addition to housing enterprises’ symposiums and real estate symposiums, a series of real estate-related documents have been published intensively in various places recently. From the content point of view, in addition to the 10 billion yuan special fund for real estate relief initiated by Zhengzhou, most policies focus on one-on-one supervision by government leaders and strengthening supervision of pre-sale funds.

　　"Stabilizing the economic market is the primary and urgent task of economic work at present and in the next stage. Among them, promoting the healthy, stable and orderly development of real estate is an important aspect. " Ma Yujun proposed at the latest symposium held in Shijiazhuang that the real estate policy should be further rationalized and improved according to the actual situation of the city, and housing enterprises should be promoted to speed up construction. In terms of specific requirements, relevant departments at all levels should continue to increase the promotion of uncompleted residential flats, compact the responsibility chain, increase coordination, and keep an eye on the time node; Properly handle the remaining problems and speed up the solution of problems such as "difficulty in obtaining a permit" and "difficulty in moving in"; Strengthen supervision and monitoring of development projects and strengthen source and process management. At the same time, it is necessary to strengthen the supervision of pre-sale funds of commercial housing, ensure the closed-loop management and use of funds, and keep the bottom line of systemic risks.

　　For the supervision work of relevant departments, there have been "one-on-one" requirements in many places. For example, at the symposium organized by Xianyang Housing and Construction Bureau, a one-on-one assistance policy was established, that is, a department helped an enterprise to promote the early solution of the problem; The Housing and Construction Bureau of Suining, Sichuan Province also instructed all jurisdictions to carry out the linkage work between housing enterprises and real estate projects. By combing and arranging, 83 real estate development projects under construction and to be built were included in the linkage scope, and each project was linked "one-on-one" by a county (city, district) and a county-level leader of a municipal park, and at the same time, a contact person in the jurisdiction was identified; Mianning County, Liangshan, Sichuan Province, in the Notice on Measures to Promote the Stable and Healthy Development of the Real Estate Market, mentioned the mechanism of "one plate, one policy and one leadership" for the problems left over by real estate development projects (for problem buildings).

　　According to the news released by Huzhou, the Office of the Joint Conference on the Stable and Healthy Development of the Real Estate Market in Huzhou City, Zhejiang Province issued the Notice on Continuously Promoting the Stable and Healthy Development of the Real Estate in our City on August 15th, which mentioned that state-owned enterprises are encouraged to purchase the unsalable houses of difficult real estate enterprises as housing for resettlement.

　　In view of the storm of supply interruption since July and the phenomenon of "early repayment of mortgage" hotly discussed by buyers, many places have further strengthened the supervision system of pre-sale funds, and even held special bank symposiums on supervision of pre-sale funds, involving Cangzhou, Hebei, Jiujiang, Jiangxi, Changsha, Hunan, Dongguan, Guangdong, Jiangmen, Jiangsu, etc.

　　Judging from the latest real estate data released by the National Bureau of Statistics, the current situation is still not optimistic. From January to July this year, the national real estate development investment was 7,946.2 billion yuan, down 6.4% year-on-year; The sales area of commercial housing was 781.78 million square meters, a year-on-year decrease of 23.1%; The sales of commercial housing was 7,576.3 billion yuan, down 28.8% year-on-year; The land purchase area was 45.46 million square meters, a year-on-year decrease of 48.1%. Among them, the sales and investment scale of new houses in July decreased by 16% and 14% respectively compared with May, and the year-on-year decline also expanded.

　　Fu Linghui, spokesperson of the National Bureau of Statistics, said that since the beginning of this year, the real estate market as a whole has shown a downward trend, and because of the large scale, long chain and wide coverage of the industry, it has a great impact on economic growth and social livelihood. However, since the beginning of this year, all localities have insisted on housing and housing, supported rigid and improved reasonable housing demand, and introduced a number of policies to stabilize the real estate market. The overall downward trend of the real estate market has slowed down.

　　Huang Hongwei, a macro analyst of Caixin Securities, believes that with the Zhengzhou municipal government promoting the landing of the bail-out fund and China Huarong and other financial institutions participating in the bail-out, relevant departments, financial institutions and local governments will follow up quickly, and Baojiaolou will also become an important policy direction for stabilizing the economy in the second half of the year.

　　Judging from recent market news, the supervision of liquidity support measures for high-quality private housing enterprises is also expected to be further deepened. At present, in addition to Longhu’s expected syndicated loan of HK$ 3.5 billion, the market also has higher expectations for the bond issuance method of "China Credit Increase+State-owned Enterprises".
