His discoveries, which won him the Nobel prize, led to the caesium atomic clock and the hydrogen maser.

这一获得诺贝尔奖的发现产生了铯原子钟和氢微波激射器。

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。
