摘　　要：应用科罗达等效方法可将二次项型无损耗非均匀线用无损耗均匀线及集中参数元件组成的等效电路表示。该文利用伴随网络法和基于科罗达等效的等效电路,提出了二次项型无损耗非均匀线的频域灵敏度分析方法,采用类似拉氏反变换的方法获得了无损耗非均匀线的时域灵敏度公式;以无损耗非均匀线的灵敏度公式为基础,通过集中处理非均匀线的损耗,推导出了二次项型有损耗非均匀线的频域和时域灵敏度公式,为解决求解含这类非均匀线网络的灵敏度提供了一种途径。Based on Kuroda's identities, binomial form lossless nonuniform transmission line can be represented with the equivalent circuit that includes lumped elements and lossless uniform transmission line. Used the equivalent circuit and adjoint network method, the frequency-domain sensitivity analysis method of binomial form lossless nonuniform transmission line is presented in this paper. Through inverse Laplace transform, the time-domain sensitivity formulas are derived from the frequency-domain sensitivity formulas; Based on the derived sensitivity formulas and through lumping the line loss, the sensitivity formulas of binomial form lossy nonuniform transmission line are obtained.
