瑞利检验最近被用作搜索时间序列中周期性脉动的一种方法。本文讨论了这一技术，并与在X射线天文学中广泛使用的历元折叠技术进行了比较。研究发现，当脉冲为正弦脉冲或占空比较宽的脉冲时，瑞利检验提供了一种更灵敏的方法来寻找周期脉冲，例如典型的脉冲X射线源。另一方面，历元折叠对射电脉冲星典型的窄脉冲更敏感。
The Rayleigh test has been recently invoked as a method of searching a time series for periodic pulsations. In this paper, this technique is discussed and compared to epoch folding, a technique which has had widespread use in X-ray astronomy. It is found that the Rayleigh test provides a more sensitive approach to the search for periodic pulsations when the pulses are sinusoidal or of broad duty cycle, such as those typical of the pulsing X-ray sources. Epoch folding, on the other hand, is more sensitive to the narrow pulses typical of radio pulsars.
