摘　　要：本文介绍“牛顿碰撞球”的有关实验 ,并用动力学普遍定理分析它的机理。对于牛顿球之间的非弹性碰撞实验进行分析和讨论 ,其结果既体现牛顿定理的应用 ,又对工程中许多非弹性碰撞问题的研究具有指导作用。The experiment of“Newton's Cradle”is introduced and its principle is studied with the generalized theorem of dynamics.The experiments of non-elastic collision between the Newton's balls are carried out with its results discussed,by which many problems of non-elastic collision in engineering could be guided.
