摘　　要：二阶动态电路的分析理论性很强,响应情况复杂,难以实现有效教学。利用Matlab强大的功能进行电路计算和仿真,能大大提高工作效率,应用于教学中对"教"与"学"都有很大帮助。首先对二阶动态电路零输入响应进行理论分析,介绍四种情况放电过程及特点,然后分别用Simulink仿真、Matlab编程仿真、GUI仿真三种方法对同一个欠阻尼情况下二阶电路零输入响应进行仿真,得到响应解析解和数值解,通过三种方法的实践对比,介绍Matlab软件在动态电路分析方面的优越性,应用于教学通用性强,效率高。Second-order dynamic circuit is highly theoretical and complex in response, it＇s difficult to realize effective teaching. Because of the powerful function of Matlab, it can be used in the circuit calculation and simulation to improve working efficiency greatly, and provide help in the teaching for both ＂teaching＂ and ＂ learning＂ . At first, analysis of the zero input response of second-order dynamic circuit is carried out, and the discharging process and characteristics for four situations are introduced, then the zero input response of a same second-order circuit in under-damped situation is simulated using Simulink, Matlab programming and GUI method, getting analytic solutions and numerical solutions. Through the comparison for the three methods the advantages of Matlab in circuit analysis are introduced, which has strong versatility and high efficiency used in teaching.
