摘　　要：RLC串联谐振是大学物理实验的一个重要内容.实验中发现电路品质因数的实验值总是小于理论计算值.对电路中的损耗电阻进行了估算,并对品质因数的理论值进行了修正,从而有效地降低了实验相对误差.RLC series resonance is an important part of college physics experiments.It is found that the measured quality factor of the circuit is always less than the theoretical value in the experiment.In this paper,to reduce the experimental error effectively,the theoretical value of quality factor is corrected by the loss resistance.

关 键 词：串联谐振 品质因数 损耗电阻
