摘　　要：首先用质点和质点系的动量定理导出变质量物体的动力学方程,然后从质点及质点系的角度对方程的物理含义进行理解,对有关文献中的说法进行讨论,最后通过实例加深对方程的理解和运用.This essay, first, derives the kinetic equation of change-quality substance by means of the theorem of momentum about mass point and the system of mass point. Then, understand the implications of the equation of physics from the viewpoint of the mass point and its system. Next, discuss the perspectives in related-articles. Finally enhance the understanding and application of the equation by concrete examples.
