摘　　要：提出了一种求解含抛物线型有损非均匀线网络频域灵敏度的方法。该方法首先将抛物线型有损非均匀线用科罗达(Kuroda)等效方法变换成有损均匀线及若干集中元件组成的等效电路,然后借助伴随网络方程法求出抛物线型有损非均匀传输线等参数的频域灵敏度。给出了计算实例,并通过扰动法进行了验证。Method is presented for the evaluation of the frequency-domain sensitivity of networks which include para- bolic lossy nonuniform lines in this paper. Based on Kuroda＇s identities, the parabolic lossy nonuniform line is trans- formed into a equivalent circuit composed of a uniform line and a cascade connection of lumped element sections at first; Then the frequency-domain sensitivity are derived by the adjoint equation method through the equivalent circuit. Example and comparisons with sensitivity determined by the perturbation method are presented.
