摘 要:北京冬奥会冰上项目场馆采用CO_(2)跨临界直冷循环技术,不仅可以减少炭排放,也可以有效保证冰道表面的平整度和稳定性.本研究通过分析2022年北京冬奥会及相关世界锦标赛短道速滑比赛场馆的冰面质量指标与运动员成绩之间的相关性,证明了冰面质量对竟技成绩的影响.主要目的是考察冰道冰质情况与成绩之间的相关性.数据显示,短道速滑男子500 m、女子500 m以及女子1000 m 3个项目成绩与场馆冰质呈现显著正相关性,皮尔逊相关系数分别为0.982、0.562以及0.588.另外,男子1000 m成绩与场地冰质呈现正相关,皮尔逊相关系数为0.266.研究表明北京冬奥会冰上项目场馆采用CO_(2)跨临界直冷循环技术与短道速滑运动员提高成绩具有一定的相关性.The ice sports venues of the Beijing Winter Olympics adopt CO_(2) transcritical direct cooling cycle technology,which can not only reduce carbon emissions,but also effectively ensure the smoothness and stability of the ice track surface.By analyzing the correlation between the ice quality index of short track speed skating venues in Beijing 2022 Winter Olympics and related world championships and athletes'performance,this study proves the influence of ice quality on competitive performance.The data shows that the men's 500m,women's 500m and women's 1000m short track speed skating events have a significant positive correlation with the ice quality of the venues,and the Pearson correlation coefficients are 0.982,0.562 and 0.588 respectively.In addition,the men's 1000-meter performance is positively correlated with the ice quality of the venue,and the Pearson correlation coefficient is 0.266.The research shows that the use of CO_(2) transcritical direct cooling cycle technology in the Beijing Winter Olympics ice sports venues has a certain correlation with the performance of short track speed skaters.
