摘　　要：针对周期性信号之间的普遍规律性,分析了等效鉴相频率和相位量子的概念.周期性信号除自身的变化规律外,周期性信号之间相互作用和联系的基础是相位量子,它揭示了周期性信号普遍联系的本质.实验证明相位量子是相互作用的周期性信号之间不可分割的基本个体,以相位量子为基础的测量、比对和控制能实现任意频率信号之间的直接相位比对.相位量子在主动型氢原子钟锁相环线路改造中简化了传输线路,减少了相位噪声引入,提高了性能。According to the universal relationship between periodic signals, a basic theory about phase quantum is proposed based on the equivalent phase comparison frequency. Besides the own periodic changes of frequency signals, the base of interactions and relationships between periodic signals is phase quantum, which reveals the key of the universal relationship between the periodic signals. The phase quantum is the necessary one of the periodic signals in the experiment. Measurement comparison and control based on the phase quantum may achieve direct comparison between different frequencies. The application of the phase quantum in the PLL circuit experiment of the active hydrogen maser can simplify its frequency transformation circuits, reduce the noise caused by those circuits and improve its performance.
