• 摘要： 北京冬奥会冰上项目场馆采用CO₂跨临界直冷循环技术，不仅可以为减少炭排放，而且也可以有效保证冰道表面的平整度和稳定性。一般认为，冰质条件与短道速滑运动成绩之间存在明显的相关性。但是这一点只能通过运动员口述得以体现，缺少量化这种关系。为了通过数据证明短道速滑比赛场馆冰面质量因素对提高竞技成绩的影响，本研究选取2022年第24届北京冬季奥林匹克运动会以及相临近世界锦标赛短道速滑比赛场馆冰面质量指标数据与短道速滑官方成绩进行相关性分析。通过此项研究结论可以为提高冰上项目运动员运动表现以及运动成绩提供技术基础。研究结果表明，男子500米、女子500米以及女子1000米三个项目与场馆冰道质量呈现显著正相关性，皮尔逊相关系数为分别0.982、0.562以及0.588。另外，男子1000米成绩与场馆冰道质量呈现正相关， 皮尔逊相关系数为0.266。数据证明，北京冬奥会冰上项目场馆采用CO₂跨临界直冷循环技术为短道速滑运动员提高成绩提供了重要的科技保障。
• The Beijing Winter Olympics ice venues adopt CO₂ transcritical direct cooling cycle technology, which can not only reduce carbon emissions, but also effectively ensure the flatness and stability of the ice track surface. It is generally believed that there is a clear correlation between ice conditions and short track speed skating performance. But this can only be demonstrated through the athlete's dictation, and there is a lack of quantification of this relationship. In order to prove the influence of the ice surface quality factor of short track speed skating competition venues on improving competitive performance through data, this study selected the ice surface quality index data of the 24th Beijing Winter Olympic Games in 2022 and the adjacent world championship short track speed skating competition venues and Correlation analysis was carried out on the official results of short track speed skating. The conclusions of this study can provide a technical basis for improving the sports performance and sports performance of athletes in ice sports. The results show that the men's 500 meters, women's 500 meters and women's 1000 meters have a significant positive correlation with the ice track quality, and the Pearson correlation coefficients are 0.982, 0.562 and 0.588, respectively. In addition, the men's 1000m performance was positively correlated with the ice track quality in the stadium, and the Pearson correlation coefficient was 0.266. The data proves that the use of CO₂ transcritical direct cooling cycle technology in the ice sports venues of the Beijing Winter Olympics provides an important scientific and technological guarantee for short track speed skaters to improve their performance.
