摘　　要：本文针对电路教科书指出的有两种情况可能会出现冲激电流和冲激电压的情况,通过举例说明,电容电压和电感电流的跃变可以在多种情况下发生。笔者还讨论了电容电压和电感电流跃变与换路定律之间的关系,即电容电压和电感电流跃变是对实际电路理想化建模的结果。本文通过实例指出正确理解电容电压和电感电流的跃变,有助于简化电路的分析。This paper has pointed out that many kinds of circuits appear jumps in capacitor voltage and inductor current instead of that jumps in capacitor voltage and inductor occur only when loops consist of just capacitors and /without voltage sources and when cuts consist of just inductors and / without current sources. Relationship between Law of switching and jump in capacitor voltage and inductor current. This paper has explained that to grasp the connotation of jump in capacitor voltage and inductor current is helpful for simplifying the analysis of circuits through an example.
