The progress situations of Hydrogen clock in the time keeping at abroad and home were introduced, and carry outs some discusses.
介绍了国际和国内氢钟守时的进展概况，并进行了一些讨论。
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。
It is the closest the clock has come to midnight since 1953, when the minute hand was moved to two minutes away following hydrogen bomb tests by the us and Russia.
这是自1953年来时钟最接近午夜的一次，上一次是美国和俄罗斯的氢弹试验，分针移动到距离午夜仅两分钟。
