单一元器件相位测量问题的实验探讨

An Experimental Study on the Phase Measurement of a Single Component

对单一元器件相位研究问题上,理论上已经相当成熟,但是在用实验验证单一元器件相位理论的过程中,却发现实验操作在验证单一元器件上存在的短板,即用双踪示波器仍不能直接验证电感(或电容)元件两端的电压和电流的超前滞后的角度关系,为了解决这个问题,就必须重新设计测量电路,使得实验测量与理论相一致,这对培养高职学生的动手操作能力有着重要意义。

The research on single phase components has been quite mature in theory,but in the process of phase theory with experiment of a single component shortcomings have been found in the experimental operation in validation of single components. Namely,the dual trace oscilloscope can not directly verify the lead lag angle relationship between the voltage and current of the inductor(or capacitor). In order to solve this problem,it is necessary to redesign measurement circuit to make the experimental measurement consistent with the theory,which has important significance in cultivating higher vocational students' practical operation ability.
