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。
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。
In such applications, the hydrogen production rate can be lower than it is aboard a vehicle, as the hydrogen can be produced around the clock in relatively large tanks.
由于可以在一个相对较大的容器中不间断生产氢气，因此在这样一些些应用过程中，氢气的产生率可以低于车载系统的产生率。
