研究了异形小行星平衡点之间的转移轨道。提出了一种生成连接任意不规则小行星附近任意两个平衡点的转移轨道的新方法。该方法包括近似搜索、首次转移轨道修正和飞行时间延续三个步骤。特别地，将该方法应用于小行星433 Eros，并在其附近建立了连接其四个平衡点中的每两个的12个转移轨道族。结果表明：总速度增量随飞行时间的变化趋势呈减小趋势，总速度增量最小的传递轨道飞行时间最长。此外，在两个平衡点之间转移所需的速度增量可以大于由轨道能量差获得的速度增量。通过对生成的转移轨道进行补片，得到了从各平衡点出发的4次最小速度增量行程，最小速度增量行程耗时约为18 m/s。
The transfer orbits connecting equilibrium points of irregular-shaped asteroids are studied. A new method is proposed to generate the transfer orbits connecting any two equilibrium points near an arbitrary irregular asteroid. This new method has three steps, including the approximate searching, the first transfer orbit correction and the flight time continuation. Specially, this method is applied to the asteroid 433 Eros and all twelve families of transfer orbits connecting every two of its four equilibrium points are founded in its vicinity. The results indicate that the tendency of the total velocity-increment with respect to the flight time is decreasing and the transfer orbits with the lowest total velocity-increment have the longest flight time in each family. Besides, the velocity-increments required for transferring between two equilibrium points can be larger than the one obtained by the difference of the orbital energy. Moreover, four minimum-velocity-increment tours of equilibrium points starting at each equilibrium point are obtained by patching the generated transfer orbits and the minimum-velocity-increment tour cost about 18 m/s.
