The constant reactive power excitation control strategy is deducted using nonlinear zero dynamic method and the system stability under this control strategy is verified.

推导了使用非线性零动态方法实现的发电机恒无功励磁控制规律，并对采用这种控制规律后，系统的稳定性做了详尽的分析。

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。
