　　On December 27th, it was learned from the press conference of the State Council Office that in 2025, Spring Festival travel rush will last for 40 days from January 14th to February 22nd. The Ministry of Transport predicts that with the release of policies by all parties, the demand for travel in Spring Festival travel rush will be stronger in 2025, and the total amount of travel and the peak value of a single day may reach a record high. To this end, the Ministry of Transport has taken the lead in setting up a special class for comprehensive transportation in Spring Festival travel rush, striving to achieve the goal of "Safe Spring Festival travel rush, Warm Spring Festival travel rush and Convenient Spring Festival travel rush".

　　At the same time, at the end of the year and the beginning of the year, Li Yang, vice minister of the Ministry of Transport, also published the report card of traffic work in 2024, expressing that he was "very proud, excited and full of confidence" in his achievements.

　　Talking about the source of confidence in the development of the transportation industry, Li Yang pointed out that one of them stems from the endogenous power generated by huge demand. Looking back at Spring Festival travel rush in 2024, the cross-regional mobility reached 8.4 billion person-times. The number of people traveling in the 7 days of the National Day holiday reached 2 billion, especially on the first day of the National Day holiday, the travel data reached a new high: the total number of people traveling reached a peak of 330 million on October 1; Railway passenger traffic reached 21.44 million passengers, a single-day high; The traffic volume of expressways reached 68.41 million, of which new energy vehicles accounted for 15.9%. The strong travel demand injected strong impetus into traffic development.

　　The second is a stronger foundation for development. China’s comprehensive three-dimensional transportation network has reached a new level, with a mileage of 6 million kilometers. Major projects such as the Shenzhen-China Passage are completed and put into operation. Civil aviation is expected to add five certified civil transport airports, with a railway mileage exceeding 160,000 kilometers, including 46,000 kilometers for high-speed railways, about 50,000 kilometers for new highways and 8,000 kilometers for newly rebuilt and expanded expressways. There has also been a major breakthrough in international transportation channels, such as trans-Caspian transportation corridor, direct highway transportation and the opening of Qiankai Port in Peru, opening up new routes for China-Europe and China-Latin America trade.

　　The third is full of development potential. A series of economic incremental policies have continuously released the traffic dividend, and the policies of "duality" and "two innovations" have continued to be effective. In November, the growth rate of freight volume and port cargo throughput increased, accelerating by 4.2% and 3.7% respectively year-on-year, which has saved enough stamina for subsequent development and continuously promoted the steady progress of the transportation industry.

　　Looking forward to 2025, Li Yang believes that there are challenges and opportunities, and the opportunities outweigh the challenges. On the one hand, hold the policy "baton" and promote the construction of major projects. The list of major projects in 2025 has been drawn up, and the Pinglu Canal under construction, Shanghai Port Xiaoyangshan North Container Terminal, Shanghai-Chongqing-Rongjiang high-speed railway and other projects are speeding up the weaving of the national comprehensive three-dimensional transportation network.

　　Furthermore, give full play to the advantages of comprehensive transportation to help reduce costs and increase efficiency. It is estimated that in 2025, it is expected to reduce the logistics cost of the whole society by 300 billion yuan, providing solid support for the real economy, especially the manufacturing industry. It will also deepen the reform of the comprehensive transportation system, promote the reform of the railway system, accelerate the development of general aviation and low-altitude economy, and release the vitality of development through reform.

　　In addition, pay close attention to safety production and let people travel with peace of mind. In 2025, Spring Festival travel rush will carry out two nationwide investigations and rectification of potential safety hazards before and after May Day. For the Spring Festival, May Day and National Day holidays, "30 hard measures" were adopted to improve holiday safety with stricter standards. (Wu Na)

This is the 2329th article of Da Yi Xiao Hu.

Up to now, there have been three epidemic outbreaks caused by coronavirus in this century, namely, Severe Acute Respiratory Syndrome (SARS) in 2002-2003, Middle East Respiratory Syndrome (MERS) that began to spread in 2012, and novel coronavirus (COVID-19) that appeared at the end of 2019. China is a country with severe disasters in SARS and this time in novel coronavirus.

First, what is coronavirus?

Coronavirus exists widely in nature. Coronavirus was first isolated from chickens in 1930s, and it was isolated from human nasal wash more than 20 years later by scholars and named B814 virus. Later, scholars made an in-depth study of the virus from its morphology, and found that the envelope of the virus had a spinous process like a corona and a king’s crown, so the coronavirus was named from this. Its natural hosts are mainly vertebrates, and people, cows, pigs, cats and bats are all its natural hosts.

Coronavirus is slightly spherical in shape, with a diameter of 80-160nm. The "crown" on its surface is a fiber process of 12-24nm, and the end of the fiber process is also spherical. The envelope of the virus consists of two layers of lipids, with membrane protein M and fibrillary protein S interspersed between them, and some coronaviruses also have hemagglutinin glycoprotein HE. The interior of the virus is composed of RNA and nucleocapsid protein N, showing a spiral structure.

S protein is the key protein of coronavirus-infected cells, which contains host cell receptor recognition sites and is the main determinant of virus virulence. M protein is the main protein responsible for virus particle assembly. N protein is closely combined with viral RNA, which can protect viral genomic RNA through spiral stacking and encapsulation. At the same time, it can delay the growth of infected cells and make them stay in the division period for a longer time, so that viral RNA can be translated to the greatest extent. HE protein plays a key role in the formation of virus particles.

As far as virus classification is concerned, coronavirus belongs to single-strand positive-strand RNA virus, which indicates that the genetic information of coronavirus is carried by RNA, and the cloned progeny virus has a high mutation rate. After entering the host cell, it directly uses ribosomes in the host cell to produce protein needed for virus replication without transcription. Coronavirus can kill cells, thus damaging various organs, and persistent infection occurs simultaneously with acute infection, mainly attacking gastrointestinal tract, respiratory tract and nervous system.

Second, the coronavirus that humans have fought.

Before SARS, it was thought that only two kinds of coronaviruses could cause human infection. At present, there are seven kinds of coronaviruses that can infect humans, including highly lethal coronaviruses, severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV) and novel coronavirus virus (COVID-19).

The common feature of coronavirus is that it is generally sensitive to heat, and it is moderately stable in a suitable maintenance solution at 4℃, and can be stored for several years at -60℃. With the increase of temperature, the virus resistance decreases. Coronavirus is acid-resistant and alkali-resistant, and sensitive to organic solvents and disinfectants such as alcohol and ether.

The symptoms of coronavirus infection are mostly similar, mainly fever, chills, cough and so on. The main routes of transmission are droplet transmission and contact transmission.

1. SARS coronavirus (SARS-CoV)

Severe acute respiratory syndrome (SARS) was caused by SARS-CoV. By July 2003, it had spread to 24 provinces, autonomous regions, municipalities directly under the Central Government and 28 other countries in China. A total of 8096 clinically diagnosed cases were reported worldwide, and 774 cases died. Nearly 20%~30% of the patients needed mechanical ventilation due to respiratory failure, and the mortality rate was 9.6%. Epidemiology in many provinces and cities showed that the mortality rate increased with age, mostly over 60 years old. Its incubation period is within 2 weeks, usually 2~10 days. The population is generally susceptible and has a strong epidemic degree. The main onset age is 20-30 years old. The source hosts may be bats and civets. The transmission routes are mainly from person to person: droplet transmission in close respiratory tract, aerosol transmission and hand-to-hand contact transmission; Animals and people: civets/bats ~ people (possible). SARS-CoV has the general characteristics of coronavirus, but it is not a mutant of other known coronaviruses, nor is it a recombinant of known coronaviruses. SARS-CoV infects lung epithelial cells, and its S protein binds to angiotensin converting enzyme 2(hACE2) receptor, which invades and replicates in vivo. Because hACE2 is mainly in the lower respiratory tract, the symptoms of the upper respiratory tract are lacking, and the virus often peaks when hospitalized, which is easy to cause nosocomial infection of the lower respiratory tract.

2. MERS coronavirus (MERS-CoV)

Middle East Respiratory Syndrome (MERS) was caused by MERS-CoV, which was first confirmed in Saudi Arabia in 2012, affecting 27 countries and regions around the world, with a mortality rate of about 35%. According to statistics of a case, the mortality rate increases with age. The mortality rate is 39% in people younger than 50 years old and 75% in people over 60 years old. The longest incubation period is 14 days, and the population is generally susceptible. The median age of onset is 49 years old. Source host: it may be camel or bat. Transmission route: animal and human: dromedary ~ human (possible); People: Close contact. The infection site is epithelial cells in the lung, which causes explosive nosocomial transmission, and has obvious gastrointestinal symptoms and renal failure. It mainly binds to dipeptidyl peptidase 4(DPP4) in the lower respiratory tract, gastrointestinal tract and kidney, and there is no mutation that enhances human infection.

3. 2019 novel coronavirus (2019-nCOV)

Novel coronavirus was caused by 2019-nCOV. From mid-December 2019 to the beginning of 2020, 59 cases of unexplained pneumonia were reported in Wuhan, and similar cases were found in other regions and countries. On January 7, 2020, it was initially identified as "novel coronavirus", and on January 12, the WHO named the virus 2019-nCoV. Up to now, more than 70,000 cases have been diagnosed, and more than 2,400 cases have died, with a mortality rate of about 3.1%. It has spread to most provinces and cities in China and nearly 30 countries. The transmission routes may be droplet transmission, contact transmission and aerosol transmission. The incubation period is 1~14 days. At present, the source host may be a bat. Shi Zhengli’s team from Wuhan Institute of Virology has found that its genome is 79.5% identical to SARS-CoV and 40% similar to MERS-CoV. 2019-nCOV, like SARS-CoV, invaded by combining with human angiotensin converting enzyme 2(hACE2), infecting respiratory system, gastrointestinal tract and testis, affecting heart function and liver function. According to the current data, compared with SARS and MERS, it is more contagious and the mortality rate is not as high as the first two.

Third, actively protect against novel coronavirus

Personal protection requires frequent hand washing and hand hygiene. Cover your mouth and nose with paper towels when coughing or sneezing, which can effectively prevent the spread of droplets. Wear masks in public places, avoid contact with animals with unknown health conditions, and reduce the trading of live birds and wild animals.

At present, various industries have started to return to work. For the office, everyone should actively declare their health. If there are suspicious symptoms such as fever, fatigue and cough, it is recommended to seek medical advice in time, avoid going to work sick, strengthen ventilation and ventilation in public areas, clean and disinfect public areas and public goods regularly, keep the environment clean and hygienic, keep a proper distance when there are many people in the unified office area, and reduce centralized meetings by video and teleconference.

Many people have taken or are planning to take a shot of flu vaccine, but they may be blindsided as soon as they come to the vaccination clinic-how can there be so many kinds of flu vaccines?

● There is "inactivation" and "inactivation";

● There are "injections" and "nasal sprays";

● There are "trivalent" and "tetravalent";

● There are "cracking" and "subunits".

And each kind, there are different brands and different prices of products. In another hospital, I found that there are different choices.

I just want to get a good vaccine. Why is it so difficult and brain-wasting?

How to choose the flu vaccine?

For the flu season in 2023/2024, there are the following flu vaccines in mainland China [4]:

● Children from 6 months to 3 years old: trivalent inactivated influenza vaccine and tetravalent inactivated influenza vaccine are available;

● Children and adults over 3 years old: trivalent inactivated influenza vaccine and tetravalent inactivated influenza vaccine are available;

● Children aged 3 to 17: There is also a trivalent live attenuated influenza vaccine.

Is it a little winding? It doesn’t matter, a table shows clearly:

At present, influenza vaccines that need intramuscular injection are all "inactivated" vaccines (commonly known as "dead vaccines").

The "dead" vaccine does not contain live viruses, and vaccination will not make people get the flu. Generally, sufficient immunity is generated after 2 to 4 weeks of inoculation.

The flu vaccine that needs nasal spray is an attenuated live vaccine, which is suitable for people aged 3 to 17.

Studies have shown that nasal spray can produce nasal mucosal antibodies in as little as 3 days [5].

Therefore, for those children who are particularly afraid and resistant to "injection" or have skin diseases in their upper arms and no suitable injection site, "nasal spray" vaccine seems to be a more friendly choice.

However, those children who have immunodeficiency diseases, received other attenuated live vaccines (such as measles vaccine, chicken pox vaccine, etc.) within one month, or have severe rhinitis, nasal congestion, runny nose and other symptoms are not suitable for vaccination.

Of course, no matter inactivation or inactivation, it has a good protective effect and can be selected as needed.

The "price" in the vaccine name does not mean "price", but refers to the type of the same pathogen.

For example, "trivalent pneumonia vaccine" can prevent infections caused by 13 kinds of pneumococci; The "9-valent HPV vaccine" can prevent infections caused by 9 kinds of HPV (human papillomavirus).

The higher the "price", the more types of pathogens are covered, and the wider the infection can be prevented (many people will mistakenly write it as "intermediary" and "rank", which is wrong).

Influenza viruses that can infect humans and cause widespread epidemic are mainly H1N1 and H3N2 subtypes of influenza A and Victoria and Yamagata strains of influenza B..

The tetravalent influenza vaccine can prevent one more influenza virus (Yamagata strain B) than the trivalent influenza vaccine.

At the end of September this year, the World Health Organization (WHO) believed that since March 2020, Yamagata strain of influenza B had not been monitored and isolated worldwide [6].

This may be related to the epidemic situation in COVID-19 in recent three years and its prevention and control, especially the changes in people’s living habits and behaviors (such as wearing masks, reducing travel and increasing social distance) [7].

However, the fact that the virus has not been detected for the time being does not mean that the virus has "completely disappeared" and there is still the possibility of making a comeback in the future. As a precaution, WHO continues to provide recommendations on the composition of tetravalent influenza vaccine [6].

Therefore, for this year, playing 3 prices is enough; At 4 prices, you won’t lose. When choosing a flu vaccine, you don’t have to worry about the specific price.

Some people may have found that the same "inactivated" vaccine is also divided into "split" and "subunit". What’s the difference?

In fact, inactivated vaccine is to completely "kill" pathogens (such as influenza virus), take their "corpses" and make them into vaccines after processing.

Some inactivated vaccines use whole bodies, such as inactivated hepatitis A vaccine, rabies vaccine and COVID-19 vaccine.

The "split" vaccine is to split, disintegrate, filter and purify the dead virus, which greatly reduces the adverse reactions of the vaccine [8].

The "subunit" vaccine goes a step further, removing the internal protein of the virus and only extracting some components (such as neuraminidase and hemagglutinin of influenza virus), with less impurities [9] and better safety.

However, at present, the production of "subunit" influenza vaccine is relatively small and the price is more expensive.

The Technical Guide for Influenza Vaccine Vaccination in China issued by China Center for Disease Control and Prevention indicates that people who can vaccinate vaccine products of different types and manufacturers can voluntarily vaccinate any kind of influenza vaccine, and there is no prior recommendation [4].

In other words, any kind of flu vaccine can provide us with good protection. What is important is to vaccinate in time, not to choose or wait.

May each of us spend this coming winter safely and healthily!

　　[PConline evaluation]As a niche old brand, "800 million time and space" seems more like a sentimental existence to some old users. Since the brand was founded in 1992, it has been committed to the PC market. In 2001, it was among the top ten famous brands in China. After the subsequent transformation, it engaged in the research and development and production of liquid crystal display materials, became the main domestic liquid crystal material provider, and gradually faded out of the consumer market.

　　Until this year, Huishijie Electronics Co., Ltd. was authorized by the brand in the field of 800 million time and space display, and the "800 million time and space" products returned to the PC market. BM320F is the masterpiece of big screen, with 32-inch IPS-ADS panel and 10.7mm slim steel frame, which strives to bring strong visual impact to consumers in both display effect and appearance.

● Monitor specification parameters

　● Introduction to the features of BM320F in 800 million time and space:

　　The above table lists the basic parameters and features of this new product. You can read it in detail to deepen your understanding of this product. Let’s start with PConline and make a detailed evaluation of it.

Appreciation of appearance and details of BM320F in 800 million time and space;

　　800 million time and space BM320F is a 32-inch large-screen display, which is made of IPS-ADS panel material, closely follows the fashion trend in appearance, and incorporates the minimalist design concept and extremely narrow bezel, making this display more eye-catching.

　　The clean back is made of matte texture, and the screw holes on the back indicate that this large-screen monitor supports wall hanging function.

　　BM320F will make the fuselage thickness 10.7mm in 800 million time and space, and the slim design will make the fuselage light and thin. Aluminum alloy middle frame is used around the screen to ensure the strength of the fuselage.

　　The border of the 800 million-hour BM320F is one of its appearance features. The super-large screen size is matched with the extremely narrow border of only 6.7mm, so that the line of sight is not limited by the border, thus having a better view.

　　BM320F in 800 million time and space puts the physical OSD button at the back of the display with the logo on the front, which is both beautiful and convenient to operate.

　　Electroplated aluminum alloy die-casting base, beautiful luster, showing gorgeous and elegant temperament.

　　In terms of interface, it is equipped with two common video input interfaces, DVI and VGA, which basically meet the needs of users for multi-platform access.

　　According to the nameplate information, the power of this 32-inch large-screen monitor is only 35W, and its energy-saving and environmental protection features make it suitable for bulk purchase in Internet cafes, offices and other places.

● Gray scale test

　　Gray scale refers to the hierarchical relationship between the darkest black and the brightest white of a display. In terms of contrast between light and dark and black and white color transition, the clearer the image, the more natural the transition, the better. On the gray scale, the performance of 32-level gray scale and 256-level gray scale is mainly used for testing.

　　In the 32-level gray-scale real shot, the color scale display of BM320F in 800 million time and space is relatively general, although there is no obvious color difference, and the gradient range is small. The boundary of some color blocks in the upper left corner is not clear, so it is difficult to distinguish.

　　However, it performed well in the 256-level gray scale test. It can be seen from the real shot that this gray scale gradient has a wide transition range, and the transition is more natural and distinct than the 32-bit gray scale, and most of the squares are completely displayed.

● Test

　　In terms of color saturation, the brighter and more transparent the picture displayed by the display, and the smoother the transition, the better the performance, and vice versa.

　　800 million time BM320F adopts IPS-ADS panel, which has good performance in color saturation, clear image quality and full color. Excessive is natural, and the color has high permeability.

● Test

　　In the real shot, there are slightly dark areas on the left and right edges of BM320F screen in 800 million time and space, but the overall dark part is not obvious, which is good enough for a 32-inch screen.

　　There is no light leakage at the edge of the screen when the monitor is in a real black picture. Excellent performance.

● Contrast test of image restoration effect

　　The following chart is a comparison between the real shot and the original picture, from which we can basically see how the color reproduction effect of a display is.

　　Note: Due to the shooting of the camera, there will be some loss in the real shot picture, and the style of the picture will be different due to the different cameras. Here is for basic reference only.

　　It can be seen from the comparison chart of the color reproduction effect of the picture that the BM320F display in 800 million time and space has a deep reproduction of the red in the three primary colors, and the other colors are still more accurate; In the natural scenery picture test, the color of the safflower picture is biased, and the color is more orange. The green plant map is slightly brighter; The ultra-high contrast of this monitor is excellent in LCD pictures, which can highlight the details of the picture. The character’s skin color is slightly brighter, and the overall restoration effect is more natural and delicate.

● Measured data of BM320F display in 800 million time and space.

　

　　The 800 million space-time BM320F adopts IPS-ADS high-definition panel, and the viewing angle can reach 178. From the real shot pictures, the multi-view images are uniform, the colors are consistent and the brightness distribution is uniform. It can easily meet the viewing needs of users from different angles.

● Display brightness | Contrast | Color gamut | Color temperature | Color level | Brightness uniformity test

　　The following data were tested by the professional monitor screen color correction instrument "Starscream Spyder4Elite 4". The test items include color gamut coverage, color reproduction accuracy, color temperature consistency, chromaticity uniformity, brightness uniformity, gamma curve and so on.

Color temperature of ambient light: 6500K K.

Ambient light illumination: 51Lux

Signal input: DVI

Comply with ISO3664 standard.

● Color gamut test:

Color gamut coverage: 97% sRGB 76% AdobeRGB

　　After measuring the color gamut of this monitor, it is found that its sRGB color gamut can reach 97% and Adobe RGB color gamut can reach 76%, and the color gamut coverage is relatively normal, which basically meets the needs of mass users for color diversification.

● Brightness uniformity test

　　According to the brightness uniformity test, the brightness value of 225.1cd/㎡ in the center of BM320F is the highest, while the brightness value in the lower left corner is the lowest, which is 198.3cd/㎡, and the brightness difference is 12%. Compared with the 32-inch screen, the overall uniformity is controlled in an acceptable range, and the overall screen display is even and soft.

● Color temperature consistency test:

　　The purpose of color temperature consistency test is to test the stability of white point color temperature of display under different brightness.We test the brightness of all-white picture and all-black picture as well as chromaticity coordinates when the brightness level is 0%, 25%, 50%, 75% and 100% respectively, and calculate the contrast and color temperature values. The color temperature value and contrast ratio should not change much under each brightness.

　　In 800 million time and space, the white point color temperature of BM320F is kept at 7300K under different brightness, and the performance is very stable. Compared with the standard 6500K color temperature, the overall display effect is slightly cooler.

● Color standard test

　　In terms of color accuracy, Δ E value is regarded by us as a key indicator to measure the quality of a product, Δ The closer e is to 1, the more accurate the color standard is. The average of this monitor Δ E is only 1.11, which is very close to the standard level, and the overall performance is excellent. And Δ The maximum value of e is only 3.81, which shows that this monitor has a high level of accuracy in color reproduction.

When △E≤ 1, the human eye can hardly distinguish the difference between the two colors;
When 1<△E<3, the human eye needs to be able to distinguish subtle color differences after comparison;
When △E<5, the human eye can distinguish the color difference and consider it as two similar colors.
When △E>5, most people can see the color difference and think it is a completely different color.

Summary of PConline evaluation room:

800 million time and space BM320F　　picture　　evaluating　　forum　　quote

　　As a large-screen display suitable for Internet cafes and home audio-visual entertainment, the 10.7mm slim body and 6.7mm ultra-narrow bezel of the 800 million-hour BM320F, supplemented by baking paint, have a noble and simple appearance. In terms of screen display, the performance of BM320F is also remarkable. IPS-ADS panel provides ultra-wide visual range and 16.7M color number display, and the performance of color reproduction accuracy is in the upper-middle level.

As one of the core components of automobile, engine not only determines the quality of automobile, but also determines the temperament of automobile. Under the influence of manufacturers and media for many years, consumers generally understand what kind of output performance will be brought to the engine behind the parameters such as displacement, torque, horsepower and power. However, in the vehicle configuration table, the engine will have a label, engine cylinder diameter and stroke. What information is hidden behind these two parameters?

Influence of radius ratio on engine dynamic characteristics

????

Simply put, the cylinder diameter refers to the diameter of the cylinder piston (inner wall diameter), and the stroke refers to the distance from the retraction to the extension of the piston rod. We all know that engine power is basically determined by engine displacement, and engine displacement = π× square of cylinder radius× stroke× number of cylinders, so the product of cylinder diameter and stroke determines engine power.

?

Under the premise of constant displacement, engine cylinders can be designed into different combinations, which can be generally divided into three types: cylinder diameter > stroke, short stroke engine; Cylinder diameter = stroke, equal stroke engine; Cylinder diameter < stroke, long stroke engine. The ratio of cylinder diameter to stroke is called radius ratio, which is an important parameter to judge the high and low speed of the engine.

?

The design of short-stroke engine with large cylinder diameter will increase the engine area and occupy a larger space in the engine room, but relatively, the engine height will not be too high, so it can effectively reduce the focus of the whole vehicle and ensure high-speed stability and handling performance. In terms of power output, short-stroke engines generally have higher rotational speed, because after the stroke is shortened, the stroke that a single work pushes the piston will also be shortened, and the number of times of doing work in the same time will also increase accordingly, and the output power will be greater, with the disadvantage of low torsion difference.

?

The long-stroke engine is designed with a small cylinder diameter, so the engine occupies a small area, and the front of the engine can be designed to be shorter, giving space to the cab behind. However, the longer stroke leads to the higher height of the engine, which hinders the reduction of wind resistance and streamline modeling design, and the higher center of gravity is not conducive to high-speed handling performance. Generally, the engine with long stroke design will have a low speed of peak torque. Because the piston runs once in the cylinder for a long time, the dynamic acceleration is high, so the torque is easy to increase. The disadvantage is that the top speed is not high, and because of the long stroke, the jitter problem of the engine is obvious.

?

The performance of constant stroke engine is between short stroke engine and long stroke engine. Although the short-stroke engine has high speed and stable output, it has no advantage in spatial layout, so the equal-impact engine is a compromise method, which keeps a certain cylinder diameter and a certain stroke, for example, Subaru 2.0L FA20 engine cylinder diameter = stroke diameter = 86 mm.

?

Therefore, it can be seen that the longer the engine stroke, the greater the displacement of the engine, but if the stroke is too long, stability and bending performance should be considered, while the short-stroke engine has high speed, low vibration and stable operation, but the manufacturing cost will be higher. Therefore, at present, the cylinder diameter ratio of short-stroke engines is generally not more than 1.3: 1, and those that exceed 1.3: 1 are reinforced, and so are long-stroke engines.

Is it better to have a larger stroke or a larger cylinder diameter?

????

A good understanding of the relationship between cylinder diameter and stroke can explain why some cars reach the red line at 5000 rpm, and some cars still have no fuel cut at 8000 rpm. Even if the same brand has the same engine with the same displacement and different models, its speed will be different. So, what effect does the speed have on consumers?

?

From the performance point of view, the stability of high rotation output of short-stroke engine is king, the starting acceleration is not high, and the speed is its specialty. Of course, high speed certainly means high fuel consumption, because the piston runs up before a drop of oil is used up, so the engine with high speed has high fuel consumption and emissions, which is generally suitable for sports cars or sports cars.

Comparatively speaking, the long-stroke engine is more space-saving in design, and the layout in the engine compartment is more convenient and changeable. For car companies, even if a new model is introduced later, it can be easily adapted with a little optimization, so it is more popular, which is not necessarily a bad routine for consumers.

?

Short stroke, small reciprocating inertia of the engine, suitable for high rotation; On the contrary, long stroke, large engine inertia and good low torque. Therefore, long-stroke engines that are good at emitting large torque in low-speed areas are more suitable for vehicles that require higher traction but lower speed, such as off-road vehicles, SUVs, trucks and so on. This kind of long-stroke engine generally has good torque characteristics and good starting performance, and the long stroke makes the engine burn more fully, so the fuel consumption is less, so it is very suitable for ordinary people to use. Now many ordinary cars also use long-stroke engines.

?

With the development of science and technology, in order to save mold and design costs, some large companies use engines with the same diameter-to-diameter ratio for their sports cars, cars and off-road vehicles, that is, several engines with different displacement share the cylinder block, and only adjust the number of cylinders or ECU driving computer to meet the needs of different models. For example, Volkswagen does not name every engine with a displacement, but all engines that use a cylinder are called the same name, and the prefix of the name is the same. EA113 is the code name of the engine block. This series of engines have been used in the fifth generation GTI, Audi TTS, Passat B5 and other models of golf.

???

Yaston’s nodule

?

For Keyboard Man, it is the most basic skill to know the performance of the engine by looking at the parameters. It is impossible to determine the performance of the engine just by looking at the basic parameters such as displacement, torque and power of the engine. Cylinder diameter and stroke should also be considered as important information, which is also applicable to ordinary consumers.

　　In the minds of many people, off-road is almost the same as personal extreme adventure and challenge. However, is it just two parallel lines between family and off-road? In fact, the yearning of family groups for off-road is equally passionate. Many parents are not satisfied with their children only learning about the world through books or screens, but hope to take their children to climb the hill to see the world, and to gain growth in exploring nature and challenging themselves. The birth of the second-generation Haval H9 perfectly meets this need, becoming a bridge connecting families and nature, allowing every family to join hands on a cross-country journey that goes as soon as they say it.

　　Now, this car is officially coming to the front of the stage. At the pre-sale conference of the second-generation Haval H9 held on August 25, the pre-sale price of the car was announced. It is reported that this pre-sale, the second-generation Haval H9 provides a total of three versions, including the exploration version, the expansion version and the polar version. The pre-sale prices are 205,900 yuan, 221,900 yuan and 235,900 yuan respectively. Now you can also enjoy limited-time car purchase rights when you place an order, which is a cash gift of 2,000 yuan for the purchase of the car, as well as a replacement subsidy of 20,000 yuan for the old owner of the H9 and a replacement subsidy of 15,000 yuan for other products or foreign products.

　　Focusing on family off-road needs, Haval opens up new family off-road categories

　　With the improvement of quality of life and the rise of outdoor activities, more and more families are beginning to re-examine and adjust their parenting methods. They are no longer satisfied with the shallow parent-child interaction of just walking in the city park or playing in the indoor playground on weekends, but hope to drive their children to explore a wider and more unknown natural world. This transformation is not only an innovation of the traditional leisure model, but also a new exploration and reconstruction of the parent-child relationship.

　　However, when it comes to cars suitable for family use, many people first think of "dad cars", which are often labeled as "refrigerators, color TVs, large sofas", focusing on the ultimate display of intelligence, comfort and luxury, focusing on satisfying people’s physiological experience. However, for families pursuing a hardcore lifestyle, children who have seen the world are stronger. The best refrigerator in the world should be a mountain spring, the most comfortable sofa is a beach and grass, and the best TV is a galaxy starry sky. Such families seek not only physical experience, but more importantly psychological satisfaction. They hope to drive an off-road vehicle that combines strength and comfort, take their children away from urban hotbeds and electronic pacifiers, and drive between the vast world, let them touch the temperature of the earth with their hands, and feel the speed and direction of the wind. During this journey, children will learn to observe, think and deal with challenges, and maintain courage and tenacity in the face of fear and difficulties.

　　A car that can carry a family off-road should not only have strong off-road ability and performance, but also have enough comfort to ensure that parents and children enjoy the journey all the way. And such off-road vehicles have always been blank in the market: light off-road is guaranteed in terms of comfort, but off-road strength is limited, often stopping before rugged, and the most beautiful scenery cannot be seen; although hardcore off-road can cross magnificent mountains and rivers, it is difficult to hide the bumps of the journey, and there is less comfort and comfort.

　　As a global SUV expert, Haval SUV has more than 30 years of deep accumulation in the off-road field, and has a keen insight and deep understanding of the Chinese off-road market. Combined with the growing demand of Chinese contemporary families for hard-core off-road experience, it has launched a "family off-road vehicle" specially tailored for family off-road – the second-generation Haval H9, which has opened up a new category of family off-road, solved the problem of taking children to explore a wider and more diverse world, and made up for the limitations of light off-road and the roughness of hard off-road.

　　When the whole family goes off-road, comfort is the top priority

　　Based on the off-road needs of families, the second-generation Haval H9 has made targeted improvements and upgrades, incorporating comfort design into every detail of the vehicle to create a more comfortable driving environment for the whole family.

　　In the previous long-term test of the second-generation Haval H 90,000, the comfort of this car was fully verified. During the journey, rough terrain and potholed road sections are commonplace, but the seat comfort of the second-generation Haval H9 gave all participants an unexpected surprise experience. It is reported that the seat is ergonomically designed, and the seat skeleton is designed with high strength, which effectively improves the support of the seat; at the same time, it adds a comfort sponge, using skin-friendly and environmentally friendly materials, which are delicate and smooth to the touch, and are more friendly to children with sensitive skin. This seat performance, coupled with the spacious space given by the 2850mm wheelbase, allows all passengers to find the most comfortable position during the journey.

　　In addition to seat comfort, the second-generation Haval H9 has also made great efforts in terms of tranquility. The car uses a variety of practical sound insulation and noise reduction technologies, such as double-layer laminated sound insulation glass, 34 laminated panels on the body design, and an optimized exhaust noise control system, which can effectively isolate external noise interference. On the long-term test line, strong wind is the norm, and Haval engineers have tested countless times, designing the A-pillar tilt angle to 39.3 ° golden angle of attack, referring to the streamlined characteristics of the dolphin’s head to reduce wind noise by 5%, even if the wind is raging outside and the sand is full of yellow sand, the car can still be relatively quiet.

　　In terms of riding comfort, the second-generation Haval H9 has also achieved the ultimate. Professional chassis tuning can better absorb the impact caused by bumpy roads, enhance the sense of rolling support, and even in desert cross-country, northwest Gobi, and various rugged terrain, there will be no "big boat" vertigo.

　　In the face of off-road challenges, reliability is the guarantee of freedom

　　Reliability is the base color of off-road vehicles. As a hardcore off-road vehicle specially designed for families, the second-generation Haval H9 shows super reliability and is not afraid to face the test of more than 30 kinds of terrain and landforms such as Gobi, desert and canyon in the long-distance survey.

　　With reliable power performance, you can reach more scenery and enjoy the same Moments. The second-generation Haval H9 is equipped with TOD intelligent four-wheel drive + Mlock mechanical lock, and can be equipped with front/rear axle electronically controlled mechanical differential lock. True three locks, the maximum wading depth of 800mm under no load, the ability to climb 100%, 7 driving modes and transparent underbody technology, these hardcore off-road equipment make the second-generation Haval H9 easy to deal with even in the face of complex and changeable terrain such as desert, Gobi, and mountains.

　　Safety is always Haval’s uncompromising bottom line. The second-generation Haval H9 adopts a non-load-bearing body design, two vertical and nine horizontal trapezoidal frame structure, and high-strength steel accounts for up to 99%. Even if it encounters a large impact force during the long test, the body is not easy to deform. In terms of active safety, the car integrates L2-level driving auxiliary features such as ACC full-speed adaptive cruise and ICA intelligent cruise assistance, which can automatically intervene at critical moments to reduce the risk of accidents. In short, the second-generation Haval H9 provides all-round protection for drivers and passengers participating in the long-distance test with excellent body structure and multiple safety protection designs.

　　In addition, whether a car is "reliable" enough is also reflected in the detailed design. The second-generation Haval H9 has been extremely polished in the front shock absorber support, body suspension, wheel hub bearing sealing design, etc. For example, the front shock absorber support has been strengthened. The second, third, and fourth body suspension have been upgraded from the compression type of the first-generation H9 to the shear type, and the three-lip sealing technology of the conventional third-generation wheel hub bearing has been upgraded to a four-lip + spring sealing structure. These measures enable it to enjoy the flying car to the fullest on the desert road, without worrying about the front shock absorber being "pierced", the violent roll when turning and accelerating, and the dust entering the wheel hub bearing.

　　Since its debut at the Beijing Auto Show, the second-generation Haval H9 has quickly attracted extensive attention in the industry and enthusiastic pursuit of consumers with its excellent product power and unique family attributes. In the subsequent Beijing Cloud Test Drive and Wanli Long Test, it has successfully pushed the market heat of this model to a new climax. Now, with the successful conclusion of the pre-sale conference of the second-generation Haval H9, the last mystery of this car has been revealed. It is reported that the second-generation Haval H9 offers three versions, including the Exploration Edition, the Expansion Edition and the Polar Edition. The pre-sale prices are 205,900 yuan, 221,900 yuan and 235,900 yuan respectively. Hardcore strength + sincere price, it is conceivable that the second-generation Haval H9 will set off a family off-road trend in the market, and the follow-up market performance is worth looking forward to.
