仿真蔡氏电路混沌效应的讨论

Discussion of Chua's Chaotic Circuit Simulation

物理实验中混沌实验是启迪大学生探索自然界非线性动力学的重要途径。传统的混沌实验仪器往往受到场地、设备和操作等条件的局限,不能很好地培养学生分析问题和解决问题能力。结合蔡氏电路原理,阐述如何实现非线性现象中倍周期分岔相图的数值模拟;并指出以上过程中培养学生兴趣、动手能力和创新意识的注意事项,为大学物理实验教学改革提供新思路。

Chaos experiment in physics can enlighten college students to explore the nonlinear dynamics phenomenon in nature.The traditional chaos experiment can’t cultivate students’ analysis capacity and problem solving skills due to the limitations of site,equipment and operation.In this paper,the realization of periodical bifurcation phase diagram was described by numerical simulation based on the principle of Chua’s circuits.Besides,items which deserve attention were pointed out in the process of arousing students’ interest,training their skills and cultivating their innovation consciousness,providing references for university physics experiment teaching reform.
