摘　　要：讨论了品质因数定义的多种表述方法,使用品质因数的一般定义对各种电路进行计算公式的推导时,过程比较繁琐,尤其当电路结构稍一复杂时,其品质因数计算公式的推导难度大大增加,因此对一般电路品质因数计算公式的推导提出了1种简便实用的方法。Various definitions of quality factor are discussed, and relations between those definitions are introduced, giving a appraisal of them in use at the same time. According to the complicated caculation of quality factor from its original definition, especially for the compound circuits, the simple method of studying the caculating formula of quality factor is provided..

关 键 词：品质因数 谐振电路 等效电抗 等效电纳
