摘　　要：本文通过建立简单的球杆模型,分别计算出完全非弹性碰撞中碰撞点在杆的质心和质心外两种情况下,系统总动能的变化与损失,从而得出动能损失与撞击位置及两者质量比的关系.In this paper, by establishing a simple ball-rod collision model, the change and di-ssipation of the kinetic energy have been calculated under the condition, when the collision point is at centre of mass of rod and off the CM in perfectly inelastic collisions. The relationships between kinetic energy dissipation and collision position have been obtained. In addition, mass of the ball and rod is another factor which has influence on the dissipation of kinetic energy. The graphs about them have been presented.

关 键 词：完全非弹性碰撞 撞击位置 动能损失
