  2022年2月20日,第24届冬奥会完美闭幕,北京冬奥会为全球观众奉献了一场视觉盛宴。响应习近平总书记提出的“中国冰雪运动必须走科技创新之路”的号召,来自清华大学机械系摩擦学国家重点实验室的马丽然副教授与其团队成员(董唱、刘媛、石志峰、黄致韬)为冬奥场地冰面的制备做出贡献,团队对不同场馆水质进行对比分析,系统研究了制冰水成分对冰表面摩擦系数的影响,并利用超滑机制,提出了一种环保绿色的制冰配方,现场测试摩擦系数较原冰面降低了30%。为冬奥冰上项目更均一、更好的冰面制备提供了重要的技术支持。

  On February 4, 2022, the 24th Winter Olympic Games opened at the National Stadium in Beijing providing a visual feast for the global audience.
  Liran Ma and her coworkers, from the State Key Laboratory of Tribology at Tsinghua University in Beijing, China, contributed to the Winter Olympic Games using tribological technologies. Inspired by the concept of superlubricity from hydration effect, the composition of water used to make ice in rinks, was well designed and regulated. They have succeeded with reducing the friction coefficient of ice by 30%, and getting more uniform and stable ice. Friction measurements were carried out in both laboratory and field tests. Field tests showed that the rinks in which ice was made by regulated water had better uniformity and lower friction. Athletes have broken Olympic records on many rinks, proving the rinks are fast venues.
