航天器动力学代码，依次实现以下要求：
（1）给出一组轨道根数OE，求出初始的位置R和速度V。
（2）根据轨道根数，用代数方程画出轨道Orbit1
（3）根据初始的位置和速度，用微分方程画出Orbit2
（4）把平面的Orbit1转换为空间的Orbit3，并与Orbit2进行比较
（5）把空间的Orbit2转换为Orbit4，并与Orbit1进行比较(The spacecraft dynamics code achieves the following requirements in turn.

(1) give a set of orbital elements OE, find out the initial position R and speed V.

(2) according to the number of orbital elements, the orbital Orbit1 is drawn by algebraic equation.

(3) draw Orbit2 from differential equations based on the initial location and speed.

(4) transform the Orbit1 of the plane into the Orbit3 of space and compare it with Orbit2.

(5) convert the Orbit2 of space to Orbit4 and compare it with Orbit1.)
