不同时段拉球对乒乓球弧圈球效果影响的探讨

The Exploration for Effect on Loop-drive at Different Times

在分析来球弹起后球的平动初速度在沿球拍切向方向和法向方向分量方向变化的基础上,对拉球时段进行重新分段,并对在不同时段拉球的摩擦过程进行物理分析,发现在不同时段拉球,对方来球平动初速度、本方法向挥拍速度、切向挥拍速度等对拉球效果具有不同的影响。

The article want to analyze the direction change process of the initial translational velocity on the tangential direction and normal direction of the opponent~ ball after the ball bounces into the air. On this basis~ we can redivide the time of pulling the ball into several periods. After analyzing the process of friction in the different periods, we find that when we pull the ball at different times, the initial translational velocity of the opponent~ ball and the speed of swing both at normal direction and tangential direction of home side have various in- fluences on pulling the ball.
