中文摘要：
针对星际探测中的借力飞行技术，基于椭圆型限制性三体模型，深入研究了借力飞行自由参数与借力飞行轨道变化之间的关系。在椭圆型限制性三体问题的假设下，通过正向和逆向积分相结合的方法，重点研究了借力天体轨道偏心率和相位角对借力飞行逃逸和俘获区域参数变化的影响，同时分析了借力天体轨道偏心率和相位角对借力飞行实现顺行轨道与逆行轨道转变区域参数变化的影响，并以地月系统引力参数为例，分析了借力天体分别对应不同轨道偏心率和相位角时，前向和后向飞越情况下，借力飞行对轨道能量和角动量的影响，总结出了相应的变化规律。这些研究对于借力飞行轨道的设计与应用具有重要的参考意义。
英文摘要：
To the Gravity-Assist technology in interplanetary exploration, basing on elhptic restricted three - body model （ERTP）, we deeply research the relative between the independent variables and orbital change of gravity-assisted flight. On the assumption that ERTP, we mainly research the influence of eccentricity and phase angle of gravity-assisted planet on parameters change of captures and escapes, direct orbit and retrograde orbit by using integrated forward and integrated backward method. Taking the gravitational parameters of Earth-Moon system as an example, we analyze, in case of before and behind flyby, the influence of difference eccentricity and phase angle of gravity-assisted planet on orbit＇ s energy and angle momentum, and summarize the corresponding the changing rule. These researches will present some significant references for trajectory design and application of gravity-assist technology.
