In chapter 3, from the viewpoint that the electron wave function of the two polar plates in the mesoscopic capacitance is coupled, we take the coupling energy into account and obtain the Hamilton of the mesoscopic LC circuit without electromotive force. 在第三章,从介观电容两极板的电子波函数相互耦合这一观点出发,考虑了介观电容的耦合能,给出了无源介观LC电路的哈密顿量(?)
With a chutes arc quenching chamber, current limiting circuit breaker can lift the arc voltage to a high value through polar voltage drop and limit the short circuit current while interrupting circuit. 它采用多个栅片的灭弧室,利用近极压降将进入到灭弧室中的电弧电压提升到一个较高的值,从而在开断电路的同时还起到对短路电流的限制。
