本文分析了RLC串联电路暂态过程时间常数τ的实验测量值与理论值偏差的原因,以频率为振荡频率的正弦波代替欠阻尼振荡波,测出电路电容和电感上的损耗电阻,对时间常数的理论值进行修正,可使τ的理论修正值与实验测量值基本吻合。
本文分析瞭RLC串聯電路暫態過程時間常數τ的實驗測量值與理論值偏差的原因,以頻率為振盪頻率的正絃波代替欠阻尼振盪波,測齣電路電容和電感上的損耗電阻,對時間常數的理論值進行脩正,可使τ的理論脩正值與實驗測量值基本吻閤。

It analyzes cause of deviation between experiment measured value of time constant and theoretical one in transient process of RLC series circuit.The loss resistance of inductor and capacitor is measured by the sinusoidal wave of the same frequency as the oscillating one of the underdamped oscillating wave.The theoretic value of time constant is corrected,and the agreement between the corrected theoretic value of time constant and the measured one can be obtained.
