Carbon dioxide refrigeration system, dry blood spot doping detection technology, pure physical method of water purification technology to prepare direct drinking water 5G, 4K to 8K ultra-high-definition cloud broadcasting equipment, underarm band-aid temperature monitoring technology. These black technologies are not only a microcosm of the wisdom to empower the Winter Olympics, but also by further improving the construction of sports infrastructure.
Make China's ice and snow-related industries and technology research and development are gradually on the fast track, but also for China's ice and snow sports to achieve leapfrog development blew a strong east wind.
Black technology trivia
CO2 refrigeration system, carbon emissions close to zero. Green environmental protection is one of the main attractions of this technology Winter Olympics, in addition to the well-known hydrogen energy cars put into use, the venue 100 percent. green power supply, the most striking is known as the ice ribbon of the National Speed Skating Hall, 1191 prefabricated components by the grandstand plate arc prefabrication technology for coding and installation after the realization of the perfect precision assembly.
Dried blood spot testing is a new technology for collecting biological samples, and by collecting whole blood samples on cardboard, storage and subsequent analysis of the samples can be realized. Compared with traditional blood and urine tests, the dried blood spot test has the advantages of small blood collection, convenience, reliability and greater sample stability, and will be a powerful tool in the fight against doping offenders at this Winter Olympics.
In order to ensure that the Olympic venues and the surrounding residents of water safety, the Winter Olympics using pure physical method of water purification technology to prepare drinking water. It is reported that this direct drinking water preparation process through the volcanic rock filtration and other physical ways to realize the disinfection of drinking water, purification, water quality in line with the current world's highest drinking water standards.
