Curling is a sport in which players deliver a cylindrical granite stone on an ice sheet in a curling hall toward a circular target located 28.35 m away. The stone gradually moves laterally, or curls, as it slides on ice. Although several papers have been published to propose a mechanism of the curling phenomenon for the last 100 years, no established theory exists on the subject, because detailed measurements on a pebbled ice surface and a curling stone sliding on ice and detailed theoretical model calculations have yet to be available. Here we show using our precise experimental data that the curl distance is primarily determined by the surface roughness and the surface area of the running band on the bottom of a stone and that the ice surface condition has smaller effects on the curl distance. We also propose a possible mechanism affecting the curling phenomena of a curing stone based on our results. We expect that our findings will form the basis of future curling theories and model calculations regarding the curling phenomenon of curling stones. Using the relation between the curl distance and the surface roughness of the running band in this study, the curl distance of a stone sliding on ice in every curling hall can be adjusted to an appropriate value by changing the surface roughness of the running band on the bottom of a stone.

冰壶是一项运动，运动员在冰壶大厅的冰盖上将圆柱形花岗岩石向28.35 m处的圆形目标传送。石头在冰上滑动时逐渐向侧面移动或卷曲。尽管已经发表了几篇论文来提出最近100年的冰壶现象的机理，但是关于该主题的理论还不存在，因为卵石冰面和冰石在冰上滑动的详细测量以及详细的理论模型计算尚未完成可用。在这里，我们使用精确的实验数据表明，卷曲距离主要由石头底部的运行粗糙度和表面粗糙度决定，冰表面条件对卷曲距离的影响较小。根据我们的结果，我们还提出了一种可能的机制来影响固化石的卷曲现象。我们希望我们的发现将成为未来冰壶理论和有关冰壶石冰壶现象的模型计算的基础。利用本研究中卷曲距离与跑带表面粗糙度之间的关系，通过改变冰壶上跑带的表面粗糙度，可以将每个冰壶厅中在冰面上滑动的石头的卷曲距离调整为适当的值。石头的底部。
