本文依据对振荡器信号特点的分析，结合反馈型振荡器的结构特点，提出了复频域形式的环路增益的构造性定义，得到了环路增益的一般计算原则。笔者进一步提出了适用于计算较为复杂的振荡器环路增益的Z参数算法，并将此算法应用到三点式振荡器这一疑难电路的计算中，对此电路起振条件的细致分析以及电压分配方式等一些关键性问题作出了讨论和验证。

Based on the recognizing for the features of the signals in oscillators, and the constructive loop gain in S-space is elucidated by properly dealing its constructional definition, therefore the general calculation idea for loop gain is introduced. Another way for the calculation is the loop-gain calculation on Z-parameters, which could be applied for the analyzing of difficult circuits. The three-terminal patterned oscillator is attentively resolved using loop-gain calculation on Z-parameters, caused the clarification for its startup conditions and distribution of voltage.
