在地心参考系中研究太阳和月亮的运动

Studies on the Sun and the Moon in the Center of Earth Reference System Transports

通过在地心参考系中研究太阳和月亮的运动得出:把地心参考系看作惯性系求出的月亮的运转周期与实际基本相符合,在精度不高的情况下,惯性力可以忽略;但求出的太阳的运转周期与实际比较相差比较大,为了与实际相符合,计算中必须考虑惯性力的大小.是否考虑惯性力,应根据实际的研究问题而定.

Studying solar and moon＇s movement in the center of earth reference system, we obtain; Regarding the center of earth reference system as inertia department ,we extract moon＇s operating cycle which is actual basically tallies. With the precision not in high situation,apparent force may be neglected; but extract of the sun＇s operating cycle is quite different with the actual. In order to accord with actual tallies,in the computation apparent force must be considered. Whether apparent force is considered, should be decided according to the actual research question.
