In this paper we give a systematic formulation of the special position and strongly unstable dynamical characteristics of the coilinear libration points of the Circular Restricted Three-Body Problem which is useful in the study of motion of small bodies. We state t he possibility of existence of conditionally periodic orbits (Halo Orbits) and give out these orbits. including lower order solutions and higher order solutions. These special periodic orbits can be used as nominal orbits for kinds of spacecrafts with different scientific goals. while the weak stability corridors associated with the coilinear libration points can be used as ones for spacecrafts with less fuel demand.

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.

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。
