A time keeping system consists of atomic clock assembly, measuring and comparing system and computation of atomic time scale, etc.

守时系统是一种需要连续、可靠运转的复杂系统，包括守时钟组、比对测量系统、原子时归算等多个环节。

Based on the requirement for establishing coordinated atomic time scale at Shangha1 Observatory, the application of ARIMA model to the forecasting of atomic time was discussed.

根据上海天文台协调原子时尺度建立的要求，探讨了ARIMA模型在原子时预报中的应用。

Based on available frequency standards: one prototype laboratory model of cesium clock, three hydrogen clocks and several (2-6) rubidium clocks, the SO atomic time scale has been established.

利用我们现有的标准，一台试验型实验室铯束标准，三台氢原子钟以及若干台(2 - 6)铷气泡标准来建立原子时尺度。

Over a few decades this would amount to a minute's difference, but over several hundred years this would mean the atomic clock time-scale and the time-scale based on the Earth's rotation would be out by an hour.
