摘　　要：通过引进一个惯性参考系证明弹性碰撞迭加性的成立,提出了用迭加性把动碰动转化成两个动碰静的方法,应用该方法计算两个小球发生两次碰撞质量比的取值范围。基于该种方法构建了其计算模型,简化了弹性碰撞中动碰动问题的复杂性,通过这种方法简化了计算的难度,增强了计算的准确性和速度。Through introducing the inertial reference system, the article proved the odditivity of elastic collision, and pointed out the method of converting movement-movement collision to two movement-static collisions and to evaluate the range of mass ratio after the secondary collision of two bails. And then, based on the method, the computing model is built, which simplifies the movement-movement collision in elastic collision. It simplified the ca/culating difficulty, strengthened the computational accuracy and speed.
