摘　　要：在电路分析中,以经典电路理论探讨非线性电阻电路的问题。针对某些可以分段线性化的非线性电阻电路,当以曲线形式给出的非线性电路的伏安特性时,探讨在凹电阻和凸电阻作基本积木块的方式下,依据电路KVL和KCL定律,运用串联分解法和并联分解法,分解拟合出满足分段线性要求的非线性电阻电路。通过对案例的仿真研究和误差分析,论证此方法当在分析非线性电阻电路分段线性时,能比较方便地逆向解决以电路的伏安特性曲线完成实际电路的设计问题。Given the volt-ampere characteristic curves of some nonlinear resistor circuits that can be analyzed by piece-wise linearization,this article provides a solution to the circuit components design by applying classic circuit theories.For circuits consisting of concave and convex resistors,it uses series-parallel connection decomposition method to achieve the circuit design that fits the given volt-ampere character,based on the KVL and KCL theories.Through simulation case studies and error analysis,it proves the effectiveness of this method for creating nonlinear circuit design from the given volt-ampere characteristic curve.
