摘要
本文绘出了求解激励为时一阶电路响应强制分量的一般表达式，同时给出了求解激励为ｔ的多项式时一阶电路响应强制分量一般表达式，使“三要素”法得以进一步概括和推广应用。
This paper presents the general expnssion of the forced component in solvingfirst-order circuit response while the excitation is Se-atsin and the one that whenthe excitation is polynome ast.It gencmlizcs and popularizes the“three-element meth-od”thurther.
