摘　　要：从冲激函数定义出发,剖析了冲激响应的实质,介绍两种求解冲激响应初始值的方法,通过比较,根据不同结构的电路,可以采取不同的分析方法,但是,根据能量有限的原理所得出的方法2,具有明显的优越性,只需将冲激源作用期间,电容看成短路,电感看成开路,就可得出冲激函数作用下的等效电路,从而可以很方便地分析出冲激函数在电路各个元件上的分布情况。这样就轻松地解决了冲激响应初始值求解难的问题。In the paper, the essence of the impulse response is analyzed, and two methods of finding the impulse response initial value are introduced. After comparing the different structure of circuits, we can adopt different methods. The method Ⅱ derived from the principle of energy finitude is superior to others. In the term of the impulse resource operation, capacitors and inductances are regarded as short circuit and open circuit respectively. From the equivalent circuit including impulse function, the distributing conditions of components of impulse function in the circuit can be analyzed easily, and the problem of finding the impulse response initial value becomes easy.
