力学碰撞中恢复系数的一般表达式

The ceneral expression for recovery coefficient

从一维正碰着手,应用质点动量定律,推导出力学碰撞问题中恢复系数的一般表达式,为我们正确理解恢复系数,解决与此相关的问题提供理论支持.

The article deduces the general expression for the recovery coefficient in solution of dynamic collision, based on on-dimension face-to-face collision and law of particle momentum conservation. It serves to understand the nature of recovery coefficient and to provide theoretic supports for solving relevant problems .
