说明：  下面的程序演示了一个原子动画模型，其中用一个在中间的球体表示原子核，另外三个球体表示电子，三个电子沿着不同的轨道绕着原子核旋转。
(Following the procedure demonstrated an atomic animation model, one of the In the middle of a spheroid nucleus express, express the three other electron sphere, along the three different electron orbits around the nucleus rotation.)
