摘　　要：从简单的蔡氏电路出发，在实验中通过改变加在运算放大器（用来构成非线性电阻）两端的正负电源电压的大小，即给运算放大器提供非对称的电源电压，从而使电路呈现丰富的非线性动力学行为。On the basis of the simplest Chua＇s circuit experiment, the voltages of the positive and the negative power supplies of operation amplifier in the circuit are changed. Period-doubling bifurcation, chaos, and periodic windows can be observed. The range of voltage parameters related with these nonlinear dynamic behaviors are found.

关 键 词：蔡氏电路 混沌 非对称电压 运算放大器
