The law that the voltage on a capacitance and the current in a inductance can't leap is deduced in the case that the voltage and the current are finite.

电容电压与电感电流不能跃变的换路定率，是在电容电流与电感电压为有限值情况下推导出来的。

With a big enough voltage between cathode and anode, they will leap at great speed from the one to the other.
