轨道保持（orbit keeping） 利用航天器上的动力装置调整航天器的速度，修正轨道参数，使航天器运行轨道与标准轨道的偏离量限制在给定范围内（常以星下点的偏离值来表征）。对不同高度的航天器，轨道保持的方法也不相同。

I am going to say if that electron is to stay in its orbit, that is to say it doesn't flee the atom, it doesn't collapse under the nucleus then the sum of the forces on the electron must be zero No net force. And so that will be the sum of a dynamic force plus an electrostatic.
如果电子会保持在它的轨道上运行,既不脱离原子的话，它就不会由于原子核对它的吸引力而被瓦解掉,电子所受的合力一定为零,由于没有合力,所以电子所受力为动态力和静电力的总和。
