对经典变质量问题的一点讨论

THE DISCUSSION TO CLASSICAL MASS-VARIABLE PROBLEM

利用动量定理、动量守恒定律及动能定理，推导变质量物体的运动方程，并给出一些基本关系式．文中结合具体事例。

By use of theorem of momentun,law of momentum conservation and theorem of kinetic energy,the moving equation of mass variable matter is deduced. Some formulas of fundamental relation of mass variable matter are given. In this paper,systematic analysis and discussion to the classical mass variable problem is made through some specfic examples.
