中文说明：能量谱分析计算,外文资料里面的源代码，包括轨道机动仿真、初轨计算,匹配追踪和正交匹配追踪，使用大量的有限元法求解偏微分方程，仿真效率很高的。
English Description：
Calculation of the energy spectrum analysis, foreign material inside the source code, including orbital maneuver simulation, initial orbit determination, matching pursuit and orthogonal matching pursuit, using a large number of finite element method for solving partial differential equations, simulation efficiency high.
