本文报道了无源铷频标中光漂移和缓冲气体漂移的计算和测量结果。光漂移是以两种接法,即分立滤光器法和集成滤光器法进行测量的。文章介绍一种能够恰如其份地描述所得结果的唯象分析方法,报道了不同的纯净缓冲气体或混合缓冲气体引起的频率漂移的测量结果,评述了频率与温度的非线性关系,将所得结果跟从前发表的数据做了比较,并且利用二次温度方程式进行简明分析,以进一步对这些结果加以说明。 This paper reports the calculation and measurement of light drift and buffer gas drift in the passive rubidium frequency standard. Light drift is measured by two methods, discrete filter method and integrated filter method. This paper introduces a phenomenological analysis method that can describe the results appropriately, reports the measurement results of frequency drift caused by different pure buffer gas or mixed buffer gas, reviews the nonlinear relationship between frequency and temperature, Comparisons were made with previously published data and concise analyzes were performed using the quadratic temperature equation to further illustrate these results.
