摘　　要：应用Matlab软件对RLC串联放电二阶电路零输入响应进行了深入分析 ,给出了脉冲放电电流峰值im 及对应的时间tm 与R、L、C等参数的函数关系 ,用计算和绘图方法证明了在R大于和小于2L/C两种情况下 ,可用统一的公式描述和计算i=f(t)、uC=f(t)、uL=f(t)、im=f(R、L、C)及tm=f(R、L、C) ,介绍了用能量守恒求该电路imBy using Matlab software, a thorough analysis has been done on response to zero input for the second order series circuit of RLC discharge. The functional relations between the peak value of impulse discharge current expressed as i m and the corresponding time t m and the other parameters, such as R,L,C respectively, has also been presented. Based on the calculation and plotting, it has been proved that i=f(t), u C=f(t). u L=f(t),i m=f(R,L,C) and t m=f(R,L,C) could be described and calculated by using an uniform formula when R>2L/C or R<2L/Crespectively. Finally, a sort of method to seek for i m by using the theory of energy conservation was introduced and validated.
