摘要: 探讨了偏心率函数的递推方法的效率, 给出了一种成批递推方法, 其计算效率明显优于直接计算方法, 而且递推是正向的. 采用该成批递推方法递推时, 偏心率函数的量级从小到大变化, 可以保证递推的精度.Abstract: Computational efficiency of the recursion of eccentricity funtions is investigated, and a kind of batch recursion method is given. Its computational efficiency is significantly superior to the direct calculation method. Moreover, this kind of batch recursion is forward so that the magnitudes of eccentricity funtions experience from small to large change in the recursive process. Hence in this way the high accuracy of the recursion of eccentricity funtions can be guaranteed.
