摘　　要：讨论了谐振电路品质因数的各种不同的定义表述及其相互间的关系,分析比较了各种定义表述的特点,指出了品质因数的功率定义所具有的合理性和优越性,并举例说明用功率定义求品质因数的便捷及根据电路元件连接情况选用储能元件无功功率的计算方法.建议谐振电路品质因数统一采用功率定义.A variety of definitions and interrelationships on quality factors in resonance electro - circuit have been discussed in this paper, whose characteristics have been comparatively analyzed, with its importance and advantage pointed out, the convenience of definitions of making quality factors by means of power has been illustrated and ways of ergastic elements of reactive power calculations based on circuit element has been chosen. Therefore, it is suggested that quality factors in resonance electro -circuit should be generally adopted in power calculations.
