Recently, at the Winter Olympics, there was a problem

Downhill skiing. alpine skiing

Originated from countries such as Austria, Switzerland, Italy and France, which are close to the Alps in Europe, it is also called Alpine skiing.

Alpine skiing includes downhill, slalom and giant slalom. Downhill is a race that crosses a gate-shaped obstacle at a high speed from top to bottom within a specified course on a snow-covered mountain. The race takes place on a hillside with a slope of 5° 35°.

The difference in elevation between the start and finish is 800,1000 metres for men and 500,700 metres for women. The total length of the course is calculated in terms of time, and the length of the downhill is about 2 minutes for men and 100 seconds for women. The width of the line is 20-25 meters.

During the race, a certain number of door flags are set up on the line, and the men are red, and the women are red and blue. The distance between the flag gates is at least 8 meters, and the distance between the upper and lower flag gates is generally about 30 meters. Small ground flags are planted every 3 5 meters on both sides of the line, with red flags on the left and green flags on the right, so as to clarify the direction of progress.

Races are scored based on two downhill times. Slalom is an alpine skiing event in which a speed of 8 10 meters per second is an alpine skiing event that continuously turns downward, crosses the gate and dodges obstacles within the specified line of the flag gate. The elevation difference of the route is 140,220 meters for men and 120,180 meters for women, of which the slope of more than 30 degrees accounts for 1 4 of the whole line.

The men's line is 600 700 meters long, with 55 75 sets of gates; The women's line is 400 500 meters long and has 45 60 sets of gates. Two flags of the same color on the left and right form an open door, and the two flags that are inserted parallel to the direction of progress are called closed doors, and the other door groups are composed on the basis of the above two kinds of doors. The width of the door is 4 5 meters, and the distance between the doors is about 15 meters.

During the race, skiers use the fastest speed and various turning methods to cross the line. The rules stipulate that skiers must pass the flag gate with both feet, and it is not a foul to knock down the flagpole, but it is a foul to miss the flag gate or ride the pole to cross the gate, and the result will not be counted. The competition requires skiers to ski once on each of the two different routes, and the results and rankings are evaluated by the two results.

The first slide foul and the second chance to slide is lost. The giant slalom is an alpine skiing event that falls somewhere between downhill and slalom. The VI Winter Olympics in 1952 were included in the official sports of the Games.

The length of the men's race is 1500 2000 meters, and the women's line is over 1000 meters, and the width of the line is about 20 50 meters. The difference in height between the start and finish is 250,400 meters for men and 250,350 meters for women, with a gradient of 5° 32°. The line signs are red and blue, and the distance between the two inner pillars of the flag gate is about 8 meters.

The race is timed twice to calculate the score. Riding the door and missing the sliding door are fouls and disqualification.

1 Alpine skiing (also known as Alpine skiing) includes Alpine combined, downhill, slalom, giant slalom and super giant slalom. In addition, ski mountaineering, which has been developed a lot in recent years, also belongs to the category of alpine skiing.

a Slalom

The so-called slalom is what we see the most on TV, skiing around one short stick after another on the way down the mountain. There are two different runs, and the two runs add up to the shortest wins, which is the case with the amateur races organized in China every year, but the trails are much shorter. The average run is 55 to 75 poles in the men's event and 40 in the women's event.

60 rods. b The slides for the giant slalom and super-G events are longer and focus on speed.

c Alpine combination is a combination of rappelling and slalom.

The reason why the Winter Olympics were not held in Tohoku was that it was too cold.

In recent years, with the global warming, the temperature in the Northeast has indeed increased, but the weather is still unstable, sometimes blowing a cold wind, and few people on the street still dare to stroll.

Ordinary people are afraid of the cold, and athletes are also afraid of the cold, and the competition clothes they wear are relatively thin, so they feel even colder. In the Northeast competition, athletes are likely to catch a cold after participating in one game and will not be able to participate in the next game, and the weather is too cold to be conducive to the normal operation of the competition and the high level of performance of the athletes.

Beijing Winter Olympics venue and schedule

The Winter Olympic venues are located in Beijing City (Beijing Division), Beijing Yanqing Dazhuang Kecun (Jin: Xidazhuang Village) (Yanqing Division) and Zhangjiakou Chongli Taizicheng Area (Zhangjiakou Division).

According to the current plan, the Beijing Winter Olympics will have 19 competition days and 228 competition units, starting on February 2, 2022, with an opening ceremony on the 4th and a closing ceremony on the 20th. Curling will be the first event to take place, with the first mixed doubles round-robin event taking place two days before the opening ceremony.

The women's 30km mass start final was the last event to conclude and was held in the afternoon of the closing ceremony. A total of 11 competition teams were formed in 15 sub-events of the Winter Olympics; The Beijing Winter Sports Events, Beijing Winter Olympics and Paralympics will use the same domestic technology as much as possible**, fully reflecting the requirements of frugality.

1.Climatic reasons. Everyone thinks that the Winter Olympics must be the colder the place, the better, at least the kind of snow that has to be covered in a large area, it seems that the Northeast is very suitable, ice and snow, but in fact, the Winter Olympics is not the colder the better, the best temperature is about 0 degrees, there is snow, but it is not very cold, suitable for athletes to play.

After all, the competitions are all outdoor events, and it should be difficult to play at the highest level if you really compete in an environment of -20°.

2.Tournament facilities. Holding the Olympic Games requires the construction of a lot of venues, as well as a series of supporting facilities, such as hotels, transportation, etc., is a complex project, need to invest a lot of financial budget, not to mention, but also consider whether these venues and supporting facilities can continue to create value after the end of the game, the population density of the northeastern provinces is certainly not comparable with Beijing, there are many venues abandoned after the Beijing Olympic Games that year, it is a pity.

So probably also to avoid waste.

3.Regarding the economy of the Northeast and the implementation of the ****, I personally think that on the one hand, several major cities in the Northeast are currently compared with Beijing or developed cities in the east and south, these two aspects are indeed lacking, but the reason for this situation is definitely not like a lot of "regional black" said, it must be caused by a variety of reasons such as history and current and climate, the national level has the ability to allocate resources to revitalize the Northeast, we personally don't want to guide the best things, so people in other places are not necessary"Yin and Yang weirdness" said how about the Northeast, and the people of the Northeast should not "not contribute traffic to the Winter Olympics", all of them have a bit of a big picture ......The little family is angry.

4. Limitations of natural conditions: The climate in Northeast China is too cold. The IOC has a restrictive condition when selecting the host city for the Winter Olympics, that is, the temperature must not be lower than -18 degrees Celsius.

Northeast China has an inland alpine climate, which is affected by the Siberian cold current, and often has low temperatures below minus 20 degrees Celsius in winter.

5. Limitations of infrastructure: There is still a lack of infrastructure construction and site construction in Northeast China. For example, the Winter Olympics will build a number of large indoor stadiums in the city that meet the requirements of ice sports and have powerful ice-making functions.

However, due to the cold climate and underdeveloped economy, northeastern cities such as Harbin and Changchun could not complete the construction.

All things considered, the combination of Beijing and Zhangjiakou is the most suitable choice for China's bid to host the Winter Olympics at this stage.

It's not that the Winter Olympics won't be held in the Northeast, but that the cities in the Northeast have been unable to apply to host the Winter Olympics.

On January 29, 2002, the International Olympic Committee (IOC) announced that the Chinese Olympic Committee had officially recommended Harbin as the host city for the 2010 Winter Olympics. At that time, a total of 8 cities made bids, and Harbin was out of the preliminary evaluation stage.

In May 2004, Harbin submitted an application to the International University Sports Federation to bid for the World University Winter Games, known as the "Little Winter Olympics", and then Harbin won the right to host the 2009 Winter Games.

In 2005, Heilongjiang Province held a special meeting to study whether to bid for the 2014 Winter Olympics, and after listening to the relevant leaders of Harbin City on the introduction of the bid for the 2014 Winter Olympics, according to the proposal of the Chinese Olympic Committee, it was agreed that Harbin would not bid for the Winter Olympics for the time being.

On 5 July 2007, the International Olympic Committee (IOC) adopted a new world-class event, the Youth Winter Olympic Games.

In August 2008, the International Olympic Committee (IOC) officially confirmed Harbin, China, and four other European cities as candidates for the inaugural Winter Youth Olympic Games in 2012.

In November 2007, the International Olympic Committee (IOC) announced that Austria's Innsbruck and Finland's Kuopio were candidates for the first Youth Winter Olympics, with Harbin in third place.

After that, Harbin once again proposed to bid for the 2018 Winter Olympics.

This time, Harbin is no longer alone, and there is another winter sports city - Changchun, Jilin Province.

But the reality is still brutal, and after an initial assessment by the Chinese Olympic Committee, Changchun abandoned the bid.

Although Harbin submitted a bid report, the Chinese Olympic Committee rejected the bid in October 2009, and Harbin was again denied the bid to host the Winter Olympics.

After a comprehensive assessment, the Chinese Olympic Committee believes that the candidate cities for the 2018 Winter Olympics are too strong, and there is a gap between Harbin and these competitors in terms of sports infrastructure construction and mass foundation.

On November 3, 2013, the Chinese Olympic Committee agreed to the bid of Beijing and Zhangjiakou to host the 2022 Winter Olympics, and sent a letter to the IOC in the name of Beijing to submit the bid to the IOC.

On November 5, 2013, the National Olympic Committee announced that it had agreed to the joint bid of Beijing and Zhangjiakou to host the 2022 Winter Olympics recommended by the Chinese Olympic Committee.

After that, Beijing successfully bid for the Olympics and won the right to host the 2022 Winter Olympics.

Moreover, it was hosted in the capital, and the political center of the capital + hosted the Summer Olympics, and Beijing had political and social prestige to convince the public. Moreover, this time it was jointly organized by Beijing and Zhangjiakou, which can be regarded as a manifestation of the integration of Beijing-Tianjin-Hebei.

If you host it in other northern places, then there is more competition. There are Heilongjiang, Jilin and Liaoning in the northeast; Other places in North China like Hebei, Shanxi, eastern Inner Mongolia, etc.; Henan in central China; Shandong in East China, northern Jiangsu, etc.; In the northwest, there are Shaanxi, Gansu, Xinjiang, western Inner Mongolia, Qinghai, Ningxia and so on.

In 2022, the Winter Olympics will be held in Beijing's urban area, Beijing's Yanqing Dazhuang Kecun and Zhangjiakou's Chongli Taizicheng area

1. Beijing is the capital

Compared with the Northeast, Beijing, as the capital of China, can highlight China's traditional culture and characteristics. Beijing is rich in Chinese elements and typical Chinese architecture. For example, the National Stadium, the venue of the opening ceremony of the Winter Olympics, is commonly known as the "Bird's Nest", as one of the landmark buildings in Beijing, the environment is very good, and it also contains a lot of Chinese culture, which is a good place to host the Winter Olympics.

Second, good resources

Beijing has a lot of advanced equipment and resources, and has a large scale of venues, the original Wukesong can be used as an ice hockey hall, the water cube can also be easily turned into an ice cube, and the capital university gymnasium can also be used as a curling venue. There are fewer suitable venues in the Northeast, and many venues need to be renovated, so the cost will be relatively high. <>

3. Temperature suitability

The reason why China chose to host the Winter Olympics in Beijing also has a lot to do with the suitability of the temperature, because this factor will largely determine the state and outcome of the athletes' competitions. According to experts, the most suitable temperature for hosting the Winter Olympics should be between minus 10 and 15 degrees, and the temperature in the Northeast is too low, which will affect the athletes' condition, and the ice surface is not the best competition conditions. Not only that, but the wind and grace will also greatly affect some outdoor skiing events, with wind speeds of less than 3 meters per second and visibility of more than 2 kilometers being the best conditions for the Winter Olympics.

To sum up, Beijing is the most suitable venue. <>

In order to ensure that China can successfully host the Winter Olympics this time and prove to the world that its country is strong, it finally chose Beijing, the capital of China, as the venue for the Winter Olympics.
