| 摘 要： | 采用分析法，对铅球出手前后的运动过程进行了生物力学和运动分析．结果发现： 铅球出手角度既具有物理特性，同时具有生物特性，它对铅球抛射远度的影响具有双重性特 征，并且其生物特性决定了出手角度在数学逻辑关系上是引起出手速度、出手高度变化的条 件．

| Abstract: | The article analyses biuomechanics and movement in the process of front and back of putting shot. It turns out th at the angle of putting shot has physical specifil property as biological specific property. these specific properties have double features on the influence of the distarce of putting shot and biological specific property decides that angle in mat hematic logic arouses the condition of tel putting speed and the change of putting height. |
