[Beijing Winter Olympics] How much do you know about the mystery behind ice and snow sports?

Come to the "Technology Winter Olympics" exhibition to find out

　　[Explanation] On January 26, "Winter Dreams Flying - China Science and Technology Museum Science and Technology Winter Olympics Theme Exhibition" was officially opened to the public for viewing experience in Beijing.

The exhibition consists of five themed exhibition areas, combining 5G, 4K, VR and other modern technical means to create a technology Winter Olympics ice and snow world for the audience to participate, interact and experience.

　　The name of this product is "Walking to the Heart". The liquid level is horizontal. If I rotate our exhibits, do you find that the liquid level gradually becomes a U shape? When our object moves in a circular motion, it will appear This centrifugal phenomenon will be thrown out, and the athlete will also be thrown out if he does not have enough centripetal force when he is turning.

What will happen to the athlete at this time? Just like the classic movements in our short track speed skating, the athlete will tilt his body to make up for the need for a certain centripetal force.

　　The name of the entire third exhibition area is called "The Secret of Motion". It is through this kind of exhibits of science and technology museums that can interact with each other to tell you the relevant principles behind our ice and snow sports, such as centrifugal force centrifugal phenomenon. , including the physical content of our action and reaction forces, including friction and so on.

　　[Explanation] In the "Charm of Ice and Snow" exhibition area, multi-sensory interactive experiential exhibits are set up to display the content, rules, equipment and athletes' stories of the 7 major events and 15 sub-items of the Beijing Winter Olympics, allowing the public to experience the winter Olympic events, feel the charm of ice and snow sports.

　　For example, skating, skiing, snowmobiles, and sledding in winter, including our curling and ice hockey, for example, we use VR equipment and this simulated equipment to make him feel like he has entered our arena.

For example, in curling, we built a small curling venue that simulates ice. Then, like biathlon, we simulated the dynamic and static transition in biathlon, skiing first, and then shooting after skiing.

Then go to experience the charm of ice sports and snow sports.

　　[Explanation] The Beijing Winter Olympics is an Olympic event equipped with scientific and technological innovations.

The "Power of Science and Technology" exhibition area of ​​the exhibition unlocks the dazzling black technology of the Beijing 2022 Winter Olympics and Winter Paralympics, displaying a series of scientific and technological achievements of China's independent innovation, including some of the latest achievements that have not yet been applied to the Winter Olympics. .

　　我们知道冬奥会它最大的特色就是冰雪，但是它目前的一些自然冰雪，它具有一个易融化的问题，为此我们就提出了一种新型的冰雪材料，这种凝胶冰雪我们通过引入高分子网络把水分子给锁住，这样它在比较高的温度的情况下，比如说常温下，它就不会发生像水这种液体流淌的一个现象。整个世界上实际上我们也是第一个做这样的材料的，(此次)冬奥会上还没有用，我们做的稍微晚了一些。我们当然希望以后会用到了这样一个材料。

　　【解说】据介绍，此次展览是在北京冬奥组委的指导下，由中国科技馆联合首都体育学院、北京理工大学等单位策划推出。
