摘要：Multisim是美国国家仪器(NI)有限公司推出的以Windows为基础的仿真工具,适用于板级的模拟/数字电路板的设计工作。它包含了电路原理图的图形输入、电路硬件描述语言输入方式,具有丰富的仿真分析能力。当改变电路连接或改变元件参数，对电路进行仿真时，可以清楚地观察到各种变化对电路性能的影响。
研究目的一是熟悉一款仿真软件（Multisim10.0)；二是通过实践研究混沌理论在生活的一般应用；三是利用典型的蔡氏电路观察混沌现象。
本文章首先介绍混沌现象的基本概念，然后叙述仿真软件，再通过研究混沌非线性电路，借助Multisims10.0仿真软件对电路进行研究，从而得出蔡氏电路（非线性电路）中一些基本结论，加深对其的了解。
关键词： multisim10.0 ， 蔡氏电路， 混沌， 非线性电路
ABSTRACT: Multisim is the U.S. national instrument (NI) Co., LTD launched with Windows based simulation tools, applicable to board level of analog/digital circuit design work. It contains a circuit principle diagram graphics input, circuit hardware description language input methods, has the rich simulation analysis ability. When changing circuit connection or change of circuit device parameters, simulation, can be seen clearly all sorts of change on circuit performance impact.
Research purpose is familiar to a paragraph of a Multisim10.0 simulation software (); 2 it is through practice research chaos theory in the general application of life; Three is to use the typical chuas circuits observation chaotic phenomenon.
This article first introduces the basic concept of chaos phenomena, then narrative simulation software, again through research, with the help of Multisims10.0 chaotic nonlinear circuits for circuit simulation software, concluded that chuas circuits research of some nonlinear circuit) (on the basic conclusion, deepen the understanding.
Key words: multisim10.0, Chaos circuits, chaos, Nonlinear circuits
