众所周知，Q因子可以由无激励问题的复共振频率计算。然而，使用两种定义来从复谐振频率获得Q因子。一种定义使用复频率的真实的部分，而另一种定义使用来自Q因子的分子的绝对值。用RLC串联电路研究了这两个定义的意义和区别，并给出了研究结果。
It is well known that Q factor can be calculated from complex resonant frequency of a non-excitation problem. However, two definitions are used to obtain Q factor from complex resonant frequency. One definition uses the real part of the complex frequency while the other uses an absolute value from the numerator of the Q factor. The meaning and difference of the two definitions is investigated using an RLC series circuit, and the findings are presented in this article.
