| 摘 要： | 系统阐述了小天体运动对应的圆型限制性三体问题共线平动点的强不稳定性特征,以及其附近的条件周期轨道——晕轨道(Halo Orbit)的存在、相应解的构造。这种特殊的轨道形式和共线平动点附近的弱稳定走廊,可分别用于在深空特殊位置附近定点有各种科学探测目标的探测器和向节能轨道过渡的通道。

| Abstract: | 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. |
