China's ice and snow-related industries and technology research and development gradually entered the fast lane, which also blew a strong east wind for the leaping development of China's ice and snow sports.
Small knowledge of black technology
Carbon dioxide refrigeration system, carbon emissions close to zero. In addition to the well-known hydrogen-powered cars and 100% venues, environmental protection is one of the main attractions of this year's high-tech Winter Olympics. Besides green power supply, the most striking thing is the National Speed Skating Hall, which is called Ice Ribbon. 1 19 1 After the prefabricated members are coded and installed by the arc prefabrication technology in the stands, the perfect and accurate assembly is realized.
Detection of dried blood spots is a new technology for collecting biological samples. By collecting whole blood samples on cardboard, the samples can be stored and analyzed later. Compared with the traditional blood test and urine test, the detection of dry blood spots has the advantages of small blood collection, convenience and reliability, and stronger sample stability, and will become a powerful means to crack down on doping offenders in this Winter Olympics.
In order to ensure the water safety of Olympic venues and surrounding residents, the Winter Olympics uses pure physical water purification technology to prepare direct drinking water. It is reported that the preparation process of this kind of direct drinking water realizes the disinfection and purification of drinking water by physical means such as volcanic rock filtration, and the obtained water quality meets the highest international drinking water standard.
