给定一组初位置和初速度即可算得卫星运行轨道根数，并转换为惯性坐标系下的三维轨道显示，同时做出了二者机械能和动量矩的比较。(Given a set of initial positions and initial velocities, we can get the number of satellite orbit and transform it into 3D orbit display under inertial coordinate system. Meanwhile, we compare the two mechanical energy and momentum moments.)
