| 摘 要： | 采用数学分析法,对铅球出手速度、角度与远度的关系以及影响程度的规律进行函数的解析分析。结果表明：出手速度对铅球远度的影响随速度的增大而增加；出手角度对远度的影响呈曲线形特征,即从0°-5°影响程度逐渐增大,到5°-20°影响最大,20°以后影响程度逐渐减少；27°以后改变角度的增量效应低于速度的增量效应；35°以后出手角度效应显著减小,理论上讲,出手角度达到35°左右时,即使出手速度不变,增大出手角度没有较大的实践意义。

| Abstract: | Adopting mathematical analysis, this paper analyzes the shot speed, the shot-putting angle and the relation between angle ＆ distance. The results show that the higher the shot speed is, the longer the distance is; the effect of the angle on the distance presents curve characteristics. |
