| 摘 要： | 本文首先对RLC串联电路中总电阻R的变化对应的五种工作状态进行理论分析,针对具有负内阻电压源的RLC串联电路在实验过程中示波器很难采集无阻尼振荡波形的现象,指出因电容电压初始值不同而得到不同振幅的无阻尼震荡波形是示波器显示波形不稳定的原因,提出改进电路,并通过仿真及实验验证了改进电路的可行性.

| Abstract: | This paper analyzes the five working states corresponding to the change of the total resistance R in RLC series circuit theoretically.Then aiming at the waveform instability of undamped oscillation and increasing amplitude oscillation during the experiment of RLC series connection second-order circuit,the paper points out the reason of instable waveform is that due to the different initial values of capacitor voltage,undamped oscillation with different amplitude is generated.The experimental circuit is impr... |
