基于对足球运动员射门技术含义的一种广义理解，定义了“限时命中率”概念，作为表征运动员射门技术的一个指标，讨论了“限时命中率”提出的依据、测度方法及实验验证的情况，研究结果表明：限时命中率完全可以用作测度运动员射门技术的一个指标，用限时目标测量限时命中率简单易行． Based on a broad understanding of football players’ shooting techniques, this paper defines the concept of “hit rate at a limited time” as an index to characterize the shooting skill of athletes, and discusses the basis, measurement method and experimental verification of the “hit rate at a limited time” The results show that the hit rate can be used as an index to measure the shooting skill of athletes. It is simple and easy to measure the hit rate with time-limited target.
