铅球最后用力阶段的数字模型及其解

Methematical Model of Shot Put before Release and its Solution

本文建立了铅球最后用力阶段的数学模型，讨论了决定铅球飞行远度的三要素间的相互关系，分析了速度角θ，力角α和加速角度α’的力学成因，进而为认识和把握现代铅球技术的本质提供了理论指导。

This paper established a mathematical model of shot put during the final exersion before release, discussed the interrelationships among the three factors that decide the performance, analysed the mechanical formation of velocity angle, force angle and acceralation angle, and provided a theoretical direction for understanding and mastering the morden shot put technique.
