| 摘 要： | 地-月系统的平动点L1点及L2点的Halo轨道在探月工程中有重要的应用价值，可分别用于地月连续通信覆盖和月球背面的探测。由于在地-月系统中太阳的引力不可忽略，特别是在长时间作用以后，其动力学行为与摄动力较小的日-地系统有明显的不同。本文分析了如何利用太阳引力进入地-月系统的L1点及L2点的Halo轨道、以及由Halo轨道进入近月轨道的问题，两者综合起来构成了一条完整的地月低能转移轨道。研究结果对探月轨道设计有一定的参考价值。

| Abstract: | The L_1 libration point and the halo orbit around the L_2 point in the Earth-Moon system play an important role in exploring the Moon.It can link the Earth with the nearside and farside of the Moon,respectively.The dynamics of the Earth-Moon system is quite different from the Sun-Earth system especially after a long duration for the gravitational attraction of the Sun.This paper deals with the problem of entering the L_1 point and the halo orbit of the L_2 point,as well as entering the low orbit around the Moon by means of the Sun's gravitation.Then a low energy lunar transfer orbits is obtained from the two latter entering orbits.This study is of high value for orbit design for lunar exploration. |
