What are the scientific and technological elements of Beijing Winter Olympics?

The scientific and technological elements of Beijing Winter Olympics are as follows:

The new paradigm of 5G network application 1 created by Beijing Winter Olympics not only broke through the key technologies for stable operation of equipment under the conditions of low temperature, strong wind, snow and ice, but also expanded many new models of 5G application, which helped the development of 5G industry in the post-Olympic era.

2. Carbon dioxide transcritical direct cooling ice-making system is the most advanced, environmentally friendly and efficient ice-making technology in the world. During the Beijing Winter Olympics, this ice-making system ensured the ice-making work in the National Speed Skating Hall, the Capital Gymnasium and the Wukesong Sports Center.

3. As a comprehensive sports training wind tunnel specially built for Beijing Winter Olympics, we can accurately study the influence of wind on competition results. Specifically, through the wind tunnel test, we can adjust and optimize the movement posture, reduce the wind resistance and air resistance during movement, and then improve the sports performance.

4. The opening ceremony of Beijing Winter Olympics comprehensively used a series of high and new technologies, such as artificial intelligence, ultra-high-definition rendering, 5G and 8K. The perfect combination of these technologies and creativity has created a magnificent and ethereal romantic audio-visual feast, which can be described as "full of science and technology".

5. Virtual simulation technology was applied in the rehearsal of the opening ceremony, which realized the whole process, all elements and all-round visual simulation from the thermal field to the torch relay. The creative arrangement and modification of the director group can be simulated in the simulation environment, which improves the efficiency of arrangement and practice and greatly reduces the cost of on-site rehearsal.
