摘　　要：在运用“RLC串联电路暂态过程中阻尼电阻与振幅和阻尼度之间关系”求临界阻尼电阻的方法中,讨论了电阻取值范围对其测量结果的影响。研究表明,当C=0.005μF,L=100 mH,电阻R的取值等于或大于800Ω时,该方法无法准确给出临界电阻的数值。In the method of calculating the critical damping resistance by using the relation between damping resistance and amplitude and damping degree in the transient process of RLC series circuit,the influence of the value range of resistance on the measurement result is discussed.The results indicate that this method can not accurately obtain the critical resistance value when R value is more than 800Ωfor C=0.005μF,L=100 mH.
