摘要
火箭升空、雨滴下落等问题,是经典力学中的变质量问题,解决这类问题,主要是使用密舍尔斯基方程。本文就密氏方程的推导、理解和应用进行专题讨论。
The rise of a rocket and the fall of a rain drop are the problems of variable mass in classical mechanics. Usually, Mischelski equation is used to solve these problems. This paper presents a special discussion on the derivation, apprehension and applications of Mischelski equation.
