摘　　要： 混沌电路是大学物理实验课程非线性系统的典型内容。为提高学生在大学物理实验课程中对非线性系统实验内容的学习效率,发挥学生学习的自主作用,介绍采用Multisim对混沌电路进行实验仿真的方法。在介绍蔡氏混沌电路基本原理和非线性电阻等效电路的基础上,叙述了在Multisim界面下对混沌电路的构建;通过设置不同的电路参数,运行仿真功能,出现了相应的李萨如图形和时域波形,并对仿真结果进行分析。说明了在大学物理实验教学中应用Multisim的可行性,为大学物理实验课程实施探究性学习策略提供可行的实验工具。 The Chaos circuit is a typical example of the nonlinear system for college physics experimental teaching. To improve the efficiency of students in learning the nonlinear system and to develop the students＇ independent role, the simulation method of Chaos circuit by Muhisim was introduced. The fundamental principles of Chua＇ s chaotic circuit and the equivalent circuit of nonlinear resistor were given. The Chaos circuit was built on Muhisim and the simulation results were obtained. This paper illustrates that the application of Multisim in college physics experimental teaching is feasible and that Multisim is a useful tool for the inquiry learning of college physics experimental teaching.
