本文建立了适于非线性微波电路ＣＡＡ与ＣＡＤ的谐波平衡算法，通过增广谐波平衡方程，微分线性化网络，非线性伴随网络等概念的引入，使得谐波平衡方程的求解和电路灵敏度的计算简捷、高效、概念清晰，且易于和已有的线性微波电路频域分析软件结合。提出了多级网络分析的松驰谐波平衡法，使得在一般的微机上可进行中等以下规模非线性微波电路的分析与设计．

The Augmented Harmonic Balance Method(AHBM)is developed for analysis of the general nonlinear microwave circuits.The concepts of differential linearized network and nonlinear adjoint network are introduced so that the formulation,computation and implementation of AHBM are rather simple and efficient and the program can be developed straightforward based on the existing frequency-domain linear microwave circuits CAD software.For the circuits of multistage structure,the relaxation technique based on AHBM is proposed to reduce the storage requirement.
