对方来球旋转性质对拉弧圈球效果的理论探讨

Theory Exploration on the Effects of Pulling loop on the Basis of the Properties and Strength of Rotation from the Other Party

通过对拉弧圈球过程的动力学分析,得出:拉对方的下旋来球比拉对方的上旋来球需要更大的切向挥拍速度,且来球下旋越强烈,切向挥拍速度要求越高,才能拉出弧圈球;为达到拉球的最佳效果,拉对方的上旋来球比拉对方的下旋来球所需较长的摩擦时间,且来球上旋越强烈,所需时间越长;拉对方下旋来球比拉对方上旋来球,回球的旋转效果更好,对方来球下旋越强烈,回球旋转也越强;拉对方上旋来球比拉对方下旋来球,回球更容易过网,且对方上旋越强烈,越容易过网,但要防止拉出台。

Based on the following two important parameters ： the ball tangential translation speed of pulling the ball at the moment of the ball leaves the racket and rotating speed, this article draws the following conclusions through the dynamics analysis of the process of loop：It needs more tangential swing speed for rival＇s backspin than topspin, and the ball backspin from rival is more intense, the requirement for tangential racquet speed is higher; To achieve the best effect of pulling the ball, the time of the friction from the rival＇s topspin is longer than the rival＇s backspin, the topspin is more intense, the time needed is longer; The effect of pulling the rival＇ s backspin is better than topspin, the backspin is more intense, and the rotation becomes stronger; It＇s easier to stock over the net for the rival＇s topspin than the rival＇s backspin, the topspin is more intense, it＇s easier to stroke over the net just in case the ball is about out of table.
