北京冬奥速递|冰壶先开战,中国两连胜:选手们到底在“擦”啥
编者按
昨日(2月2日),北京冬奥会冰壶(Curling)比赛在北京国家游泳中心“冰立方”率先拉开帷幕,这也是北京冬奥会首场正式比赛。中国冰壶队混双组合凌智/范苏圆在混双循环赛的首场比赛中通过加赛击败平昌冬奥会亚军瑞士组合,取得中国军团在北京冬奥会上的开门红。在今天(2月3日)上午刚刚结束的第二场比赛中,中国队险胜澳大利亚队,取得两连胜。
看奥运学英语,今天我们来科普:冰球选手们经常在行进的冰壶前方拼命“擦地”(刷冰),他们究竟“擦”的啥?

冰壶“擦”的到底是啥?✦
There's a technique in curling called "pebbling," meaning ice makers spraying water evenly across the curling lanes that turn into countless little "pebbles" as they freeze.
冰壶中有一种技术叫做“打鹅卵石”,意思是制冰机在冰壶道上均匀地喷洒水,水结冰后就会变成无数的小“鹅卵石”。
为啥要擦冰珠?✦
The goal the players are trying to achieve by brushing along the track of the stone is to change its direction or speed.
刷冰员通过刷石球的轨迹来达到的目标是改变它的方向或速度。
制作冰珠的水是什么水?✦
Purified water freezes faster and harder, which makes the brushing much better and allows the pebbles to stay standing tall for the whole game.
去离子水结冰更快、更硬,这使得刷冰效果更好,让鹅卵石可以持续正常比赛。
