摘　　要：将恢复系数看作与接触点位置相关的函数,利用函数关系计算斜碰过程的能量损失和弹性势能储能系数,发现可变化的恢复系数有简化斜碰问题的作用.To regard the coefficient of restitution as the function which is related to the point of contact,we utilize the function to calculate the loss of energy and the elastic potential energystored in the process of oblique collision. By investigating,the problem of oblique collision can be simplified by the variable coefficient of restitution.

关 键 词：恢复系数 能量损失 弹性势能储能系数
