Technology makes the creativity at the opening ceremony more brilliant, which is by no means a day's work. In 2017, the national key R & D plan set up a key special project of "science and technology Winter Olympics". Zhu Xuehua, director of the social development science and Technology Department of the Ministry of science and technology, introduced that more than 200 technical achievements developed by more than 500 units and more than 10000 scientific researchers have been demonstrated and applied in test competitions, sports mobilization training and formal competitions around key scenes such as venues, operation, command, security, medical treatment, meteorology, transportation, broadcasting and watching competitions, It has provided strong support for the high-quality hosting and high-level participation of the Beijing Winter Olympic Games.
Yu Hong, director of the Technology Department of the Beijing Winter Olympic Organizing Committee, introduced that the "ice" surface of the national speed skating hall was the first to be manufactured by using carbon dioxide transcritical direct cooling ice making technology in the history of the Winter Olympic Games, which provided a guarantee for athletes to create faster results, and has witnessed the birth of eight new Olympic records and one world record.
"Behind the numerous' black technologies' of this winter Olympic Games is a centralized display of Beijing's scientific and technological innovation achievements.
