| 摘 要： | 通过对击球瞬间挥拍速度与被击出的球飞出距离的关系进行了实验研究。结果发现，挥拍速度与球的飞出距离两变量间存在强相关关系。在使用３８ ｍｍ乒乓球的情况下，相关系数男子为０． ８９８，女子为０．９２２；在使用４０ ｍｍ乒乓球的情况下，相关系数男子为０． ８８１，女子为０． ８９８。用测量扣杀时球飞出距离来推算击球瞬间的挥拍速度，作为一种简便方法是可行的。

| Abstract: | The relationship between the instant speed of swing during smash and the bounce distance of the ball hit were studied by experiment. The results showed that there was close relation between the two variables of swing speed and the bounce distance of the ball. When using the 38mm ball, the correlative coeffi- dent of them for men was 0. 898, and for women 0. 922. And when using the 40mm ball, it was 0. 881 for men, and 0. 898 for women. It is a simple and feasible method to calculate the instant speed of swing during smash by measuring the bounce distance of the ball. |
