| 摘 要： | 分析了RLC串联电路欠阻尼振荡衰减系数的实验测量值与理论值存在偏差的原因.以振荡衰减的实验波形为基础,建立响应波形的数学表达式,推导出电路电容和电感上的损耗电阻,对衰减系数的理论值进行修正,可使衰减系数理论修正值与实验测量值基本一致.

| Abstract: | The reason why the experimentally measured value of attenuation coefficient deviated from the theoretical one in the under damping transient process of RLC circuit was analyzed.The loss resistance of the inductor and capacitor were measured experimentally from the attenuation curve.The corrected theoretical value of the attenuation coefficient was in agreement with the measured one. |
