| 摘 要： | 现代乒乓球运动中几乎所有技术都要借助于摩擦。制造旋转时，球拍与球之间的摩擦主要是静摩擦和滚动摩擦，它们的作用效果互不相同。静摩擦不但使乒乓球产生旋转，也使乒乓球产生平动；滚动摩擦则不利于乒乓球运动中制造旋转。静摩擦与滚动摩擦都是随时间变化的量，且两者的大小与多种因素有关。

| 关 键 词： | 乒乓球 旋转 静摩擦力 滚动摩擦力偶矩 平动 |

| Abstract: | Almost all skills in modern table tennis need friction. There were both static friction and rolling friction when playing rolling ball. Static friction generate both rotation and translation, while rolling friction is an obstacle for rotation. Both static friction and rolling friction change with the time and had related with many factors. |

| Keywords: | table tennis rotation static friction rolling friction moment of couple of rolling friction translation |
