摘　　要：加加速度在质点动力学中是经常遇到的问题 ,只是对该概念在质点动力学中没有明确提出 .描述了质点变加速度运动中的加加速度的概念 ,即加速度对时间的变化率 ;导出平均加加速度和瞬时加加速度 ,即加加速度表达式 .论述了加加速度在实际问题中的应用 .Plusing the acceleration to be living in the material point kinetics is the problem constantly encountering.Adjusting ought to approximately to attend school not to point kinetics in clearly and definitely proposes only.The original is first of all propose to depict the approximately idea that plus the acceleration in the acceleration movement that the material point changes into.In immediate future acceleration adjust time the variance ratio.Then educes equally to plus the acceleration in immediate future plus the acceleration with instantaneous and plus the acceleration style showed.Afterwards expound to plus the acceleration to be living the application in the actual problem.

关 键 词：平均加加速度 瞬时加加速度 加加速度
