The classical Hertz and JKR elastic contact theory is successfully applied to the plastic collision of cohesive particles. And the coefficient of restitution is then defined from the consideration of energy.

在经典Hertz弹性接触理论和JKR粘弹性接触理论的基础上，本文从理论上将其推广应用至粘附性颗粒塑性碰撞的情形，并从能量的角度定义了能够更加合理反映碰撞规律的弹性回复系数。

Statistic analysis result shows that the time step is the most important influence factor of simulation precision, and there is relation between simulation error and the setup value of restitution coefficient which the greater the setup value is, the less the simulation error is. Although there is no effect to the total contact time in the course of collision, the value of the time step decides the total contact step, and there is a logarithmic linear correlativity between them.

统计分析结果表明：计算时步是影响模拟精度最重要的因素；模拟误差还同恢复系数的设定值有关，设定值越大，模拟误差就越小；计算时步的大小虽然对碰撞过程的总接触时间影响不大，但是却决定了碰撞过程的总接触时步数，二者之间存在对数线性相关关系

And these 6 influential factors were analyzed with the experiment by means of range, variance and regression analysis. During the analysis, the evaluation criteria were the acceleration of rolling rock movement and the restitution coefficient of collision velocity between rolling rock and slope surface.

在试验基础上，采用极差、方差和回归分析等手段，以滚石运动的加速度和滚石与坡面碰撞速度恢复系数作为评价指标，对影响滚石在斜坡上运动特征的6个因素进行分析。

The collisions of rigid bodies is a classical problem, however, the coefficient of restitution is used in the conventional researches to study this problem. The authors present a new way for this kind of problem. A theory of the collision between two rigid bodies in two dimensions, taking account of friction, is proposed according the Newton first law. And the shortages of former researchers are justified.

刚体碰撞是力学上的一个经典问题，但目前大都采用给定恢复系数进行分析的方法，本文则直接从两刚体碰撞时Newton第二定律出发，建立了计及摩擦的两刚体碰撞基本理论，并指出了以往研究通过给定恢复系数方法的错误之处。

Results show that the equivalent mass in normal direction depends on the modes of collision. In the case of reversed sliding and sticking, the coefficient of restitution varies as a result of the instantaneously changes of the equivalent mass during impacting process. The coefficient of restitution depends not only on the contact force, but also on the kinematical and dynamic parameters of the two rigid bodies. Moreover, a formula is proposed to calculate the coefficient of restitution.

指出法向等效质量依赖于碰撞状态，在反向滑动和停止滑动这两状态下的法向等效质量是变化的，因此导致其恢复系数是变化的，这样，恢复系数不仅与接触力有关，而且还与两刚体的运动和动力参数有关，同时给出各种碰撞状态下的恢复系数计算式。
