摘　　要：利用数据采集器系统研究RC串联电路的暂态过程,绘制充放电电容电压曲线,测量电路的时间常数和电容器的电容.实验操作简单,测量精确,实现物理实验测量手段的数字化;实验数据显示、分析的智能化.The transient process of RC series circuit has been researched with the data collec- tor system. The capacity voltage curves of charging and discharging are plotted. The time constant of the capacitive circuit and capacity of capacitors are precisely measured. Our experi- ment is easily to operate and has high accuracy. A digital measuring method has been applied in this experiment. The display and analysis of experiment data are intellectualized.
