非线性电阻电路的研究The study of the nonlinear resistive circuits作者：童娟娟（0804240205）Author : Tong Juanjuan(0804240205)一、摘要：本实验初步研究了非线性电阻电路的伏安特性曲线及非线性电阻电路的综合。
在非线性电阻电路伏安特性曲线的研究中，首先了解了各种常用元件的伏安特性，为以下熟练应用打下基础；第二，认知凹电阻及凸电阻的概念，为后续分段分析伏安特性曲线打下基础。
在非线性电阻电路综合的研究中，主要学习了串联分解法和并联分解法，并用凹电阻和凸电阻作基本积木块综合出各种单调分段线性的非线性元件电路伏安特性。
经过以上两部分的研究，完成了实验要求，即：用二极管、稳压管、恒流管等元器件设计如图一图二所示伏安特性的非线性电阻电路，并测量所设计电路的伏安特性并作曲线。
图一图二In this study, I did a preliminary study of the volt-ampere characteristic curve of the nonlinear resistive circuits and the integrated nonlinear resistive circuits.In the study of the volt-ampere characteristic curve of non-linear resistive circuits,I tried to understand the volt-ampere characteristics of a variety of common components firstly, which lays the foundation for the following skilled application;Second, I learned the concept of the concave and convex resistors, which lays the foundation for follow-up analysis of each section of the volt-ampere characteristic curve.In a comprehensive study of the integrated nonlinear resistive circuit, I mainly understood the means of the decomposition by series connection and parallel connection,and then used the concave and convex resistors as a basic building block to synthesize a variety of monotone piecewise-linear non-linear volt-ampere characteristics of the circuit components.After the two parts of the study above,I completed the experiments according to the experimental requirements as follows:With diodes, voltage regulator tube, constant current design of piping and other components design nonlinear resistive circuits according to the volt-ampere characteristic curve shown in Figure 1 and Figure 2 ,measure the volt-ampere characteristics of the circuits and make curves.二、关键词非线性电阻电路nonlinear resistive circuits常用元件common components分段线性linear in each section伏安特性曲线volt-ampere characteristic curve凹电阻concave resistors凸电阻convex resistors串联分解法means of the decomposition by series connection并联分解法means of the decomposition by parallel connection三、引言理论上，一切实际电路严格说来都是非线性的。
