| 摘要: |
| 对月球探测器的返回轨道进行了建模与特性分析。在三维空间中建立了返回轨道的数学模型；对模型进行仿真分析得到从月球影响球东经80°出口的返回轨道最省能量等结论；根据模型及其特性给出初步轨道的算例，并以此结果为初值，在已有高精度动力学模型下搜索计算，较快地得到了精确轨道；通过两条轨道参数及空间形状的对比，证明文中解析方法的正确性。 |

| Abstract: |
| Mathematical model and characteristic analysis of return trajectory for lunar probe were studied. Firstly, mathematical model of return trajectory was established in 3D space; then some important characteristics were obtained from simulation analysis, especially those characteristics of trajectory escapes from lunar sphere of influence on longitude 80°E costing the least energy; at last an example with a preliminary trajectory and a precise trajectory was proposed, which proves that this analytical method is able to provide initial value for precise design，and the characteristics can guide the actual design. |
