用数值计算方法分析RC、RL串联电路暂态过程及数值计算方法在其他复杂电路分析中的应用举例。主要是用辛普生法则求积分的方法来求得流经R的电量，用隐性欧拉公式求一阶微分方程的方法来求得电压随时间的变化规律。系统的研究了RC电路和RL电路的暂态过程。

-Analysis of numerical methods with RC, RL series circuit transient process and numerical methods in analysis of other complex circuit application examples. Is mainly used Simpson　s rule quadrature method to obtain the electricity flowing through R, with the implicit Euler method of seeking a first-order differential equations to obtain the voltage variation with time. Systematic study of the RC circuit and the RL circuit transient process.
