摘　　要：用双踪示波器测量RLC电路的相位关系,必须要解决示波器的共地和只能显示电压波形而不能显示电流波形的问题。在具体参数设置过程中还应注意其它问题。when using double-trace oscilloscope to measure the phase relationship of RLC circuit ,we must solve the common ground of the oscilloscope and the problem of only voltage waveforms and no current waveforms. What＇s more, we should pay attention to other problems in the process of specific parameters setting.
