碰撞恢复系数是研究碰撞问题的重要且颇具争议的参数，对于该参数争议的焦点在于：①哪一个碰撞恢复系数的定义更合理；②碰撞恢复系数是否只与材料相关；③可否表达为其他变量的函数；④是否还存在其他更稳定的碰撞过程中的不变量；⑤不同类型的碰撞恢复系数如何应用。围绕上述焦点问题，从定义等价性、优劣、研究方法以及应用方式等各个角度进行了回顾，分析了利用碰撞恢复系数来解决碰撞问题中存在的问题，并探讨了今后的研究发展方向。
踫撞恢複繫數是研究踫撞問題的重要且頗具爭議的參數，對于該參數爭議的焦點在于：①哪一箇踫撞恢複繫數的定義更閤理；②踫撞恢複繫數是否隻與材料相關；③可否錶達為其他變量的函數；④是否還存在其他更穩定的踫撞過程中的不變量；⑤不同類型的踫撞恢複繫數如何應用。圍繞上述焦點問題，從定義等價性、優劣、研究方法以及應用方式等各箇角度進行瞭迴顧，分析瞭利用踫撞恢複繫數來解決踫撞問題中存在的問題，併探討瞭今後的研究髮展方嚮。

Restitution coefficient for impact problems is an important and controversial parameter.The controversial problems are as follows:which definition is more appropriate among those in common use;whether or not the coefficients are only related to material of colliding bodies;whether restitution coefficients can be expressed as a function of other variables;whether is there any another coefficient with stable and constant properties during collision;how to use different types of restitution coefficients?Here,revolving around these problems,the review on impact problems was made.The existing problems were analyzed when solving the collision problems by using restitution coefficients and the future study direction was discussed.
