China News Service, Beijing, April 8 (Reporter Yue Chuan) As the only newly-built ice competition venue for the Beijing Winter Olympics, the National Speed Skating Pavilion known as the "Ice Ribbon" has become a building on the Red Toner Network.
With the opening of the Winter Olympics test competition on the 7th, the "Ice Ribbon", which ushered in an official competition for the first time after completion, has once again become the focus of attention.
Among the five venues participating in the "Meet in Beijing" winter sports ice event test event, the "Ice Ribbon" is the last competition venue to be tested by the competition, which means it will be the finale.
This brand new venue with an all-ice design will host speed skating events at the Beijing Winter Olympics.
As the name suggests, this is a sport with "speed" as its core, so it puts forward higher requirements on the ice surface quality and other hardware conditions.
Players in the 8th test match
During the two-day test match, the most talked-about piece of ice in the stadium was undoubtedly.
After completing the actual sliding, the athletes who participated in the test competition gave it a high evaluation, among which there are many descriptions of "best".
And striving to create the "fastest ice" to help athletes achieve great results in the Beijing Winter Olympics, this is also the goal of the stadium ice making team.
This is a special piece of ice surface, first reflected in its size-"Ice Ribbon" has the largest all-ice surface in Asia, covering an area of nearly 12,000 square meters.
This is also an ice surface that relies on cutting-edge technology. It has also achieved a leap in environmental protection and energy saving in the pursuit of the "fastest ice".
In order to achieve this series of breakthroughs, the ice making team behind the scenes paid a lot of hard work.
National Speed Skating Stadium Ice Expert Mark Meser
According to the National Speed Skating Stadium ice expert Mark Meiser, the "Ice Ribbon" uses carbon dioxide transcritical direct cooling ice making technology, which is different from the previous new system, which is environmentally friendly and efficient.
According to data, in the all-ice mode, the "Ice Ribbon" can save more than 2 million kilowatt-hours of electricity every year only in the cooling part, and the carbon emissions of the entire cooling system are approaching zero.
In addition to environmental protection and other factors, the biggest advantage of this technology at the competition level is that the ice temperature of the ice made with it is very uniform and can basically be controlled within 0.5 degrees.
Feng Gang, deputy facility manager of the National Speed Skating Stadium, said that the most intuitive feedback given to participating athletes is that the ice surface hardness is always the same.
If the temperature difference of the ice surface is too large, it will lead to different hardness and softness of the field, which is not conducive to the skater's sliding.
On April 7, the athletes of the Beijing team were interviewed in the mixed interview area after the match.
On the same day, the "Meet in Beijing" ice event test event speed skating competition kicked off at the Beijing National Speed Skating Stadium.

As a former member of the Chinese women's speed skating team, Wang Beixing, who is now the competition director of the National Speed Skating Stadium, is deeply touched by this.
In her opinion, any factor in the field may affect the quality of the ice surface, especially the control of the temperature of the ice surface. Maintaining a uniform constant temperature will help create the "fastest ice".
"In terms of temperature control, the National Speed Skating Stadium is better." During the test match yesterday, Wang Beixing sent the match video to the relevant technical representatives of the International Skating Federation and received positive feedback.
Feng Gang also believes that this piece of ice has reached a relatively high level, but there is still a lot of work to follow.
Mastering the changes of ice surface at different temperatures through testing, further building and running the team, fully understanding and mastering the new ice-making technology, these are all important tasks.

The application of cutting-edge technology is often accompanied by the emergence of new problems.
Although Mark Meiser has a wealth of Olympic ice making experience, in his words, "Each venue has its own characteristics, which will bring different challenges." Ice making for the "Ice Ribbon" is the same.
This highlights the value of this test match.
"We can see the impact of the changes made on the ice surface, such as room temperature and other controllable variables. Now that athletes have the opportunity to get on the ice, we will collect feedback and make adjustments and improvements to the deficiencies." Mark Mai Said.
Feng Gang also revealed that this is a kind of ice-making technology with high "pressure". The whole team has been in communication with experts and manufacturers, and through tests, it summarizes the differences from traditional technology, and then masters the characteristics of this technology, and finally develops Work out a suitable plan and strive to create the "fastest ice".
He hopes to help the athletes to create more good results in the "Ice Ribbon", best to break the record, this is also the original intention of the ice-making team.

As Wang Beixing said, "the fastest ice" is the goal of all ice makers, and it is also the expectation of all athletes on the field.
In this regard, Mark Meiser believes, "There is no reason to say that this place cannot be the fastest speed skating stadium. We will try to find the correct parameters and turn them into reality. We still have a lot of room for improvement, so we continue to learn every day. There are more than 9 months left before the Winter Olympics. There will be some pressure on time, but everything is okay. Our goal is to make perfect ice for the Winter Olympics."
For the "Ice Ribbon", Mark Meiser still has his own expectations, and he hopes to make up for his past regrets here.

"We want to leave a'legacy' here. In the previous Olympics, we left after making the ice. And this venue has a sound sustainability plan, so I want to make sure that after we leave, there will be trained professionals. The personnel continue to maintain this'legacy'."
According to the plan, the "Ice Ribbon" will be built into an urban cultural and sports complex with ice and snow sports as the core to promote national fitness and sports consumption after the Olympics.
In the near future, this place will become a new landmark of China's ice and snow sports.
