This paper discusses the results of a simulation of a time scale based on continuously operating commercial hydrogen masers and an optical frequency standard that does not operate continuously as a clock. The simulation compares the performance of this time scale with one that is based on the same commercial devices but incorporates a continuously operating cesium fountain instead of the optical standard. The results are independent of the detailed characteristics of the optical frequency standard; the only requirement is that the optical device be much more stable than the masers in the ensemble. We discuss two methods for realizing the results of this simulation in an operational time scale.
本文讨论了基于连续运行的商用氢 maser 和非连续运行的光学频率标准的时间尺度模拟的结果。该模拟比较了这种时标与基于相同商用设备的时标的性能，后者则采用连续运行的铯喷泉代替光学标准。结果与光学频率标准的详细特性无关；唯一的要求是光学设备比 ensemble 中的 maser 稳定得多。我们讨论了在运行时标中实现此模拟结果的两种方法。
