摘要

研究了偏心函数递归的计算效率，给出了一种批递归方法。其计算效率明显优于直接计算方法。此外，这种批递归是正向的，使得偏心函数的量值在递归过程中经历了从小到大的变化。这样可以保证偏心函数递推的高精度。

Computational Efficiency of the Recursion of Hansen Coefficents

Computational efficiency of the recursion of eccentricity functions 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 functions experience from small to large change in the recursive process. Hence in this way the high accuracy of the recursion of eccentricity functions can be guaranteed.

期刊介绍： The vigorous growth of astronomical and astrophysical science in China led to an increase in papers on astrophysics which Acta Astronomica Sinica could no longer absorb. Translations of papers from two new journals the Chinese Journal of Space Science and Acta Astrophysica Sinica are added to the translation of Acta Astronomica Sinica to form the new journal Chinese Astronomy and Astrophysics. Chinese Astronomy and Astrophysics brings English translations of notable articles to astronomers and astrophysicists outside China.
