中文说明：仿真电容的充电过程，设t=0为初始时刻,仿真步进应远远小于系统的时间系数-Simulation of capacitor charging process, based t = 0 as the initial time step simulation system should be much smaller than the time factor
English Description：
Simulation of capacitor charging process, based t = 0 as the initial time step simulation system should be much smaller than the time factor
