摘要
该文介绍了由轨道方程计算有心力的四种方法,分析了彼此间内在的联系,并对这四种方法的难易程度进行评价,指出其中的动能导数法往往使用更为简便,它是除比耐公式法外另一实用的计算方法.
This paper introduces four methods for calculating the central force by the orbit equation, analyzes the internal relations among them, and makes an evaluation on the difficulty of the four methods. It is pointed out that the kinetic energy derivative method among them is often more simple and easier to use, and it is another practical calculation method in addition to the Binet equation method.
