摘　　要：在对两个周期性信号之间相位差变化规律和相应的新概念深入研究的基础上,结合常用的频率稳定度的测量方法,提出了一种新的频率稳定度的判定方法——基于李沙育图形的频率稳定度的快速检验方法。该方法可以用于各种原子频标和频率源的频率稳定度的测量与判定。Based on the deep research of the change law of phase difference between two periodic signals and combined with the ordinary frequency stability measurement method, this paper gives a new method that can be used in measurement frequency stability. This method is based on the Lissajous figure. The new method can be used in the measurement of atomic frequency stability and high stability frequency stability.
