atomic time

基本解释

Long?term stability of the ensemble pulsar time is obviously better than that of atomic time.
研究表明综合脉冲星时的长期稳定度明显优于原子时。
UTC Universal Time Coordinated. This is Greenwich Mean Time, adjusted to be an integral number of seconds different from International Atomic Time.
格林尼治（平均）时坐标。这是格林尼治平均时，被调整到秒的整数值，它异于国际原子时。（参考）
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。

At the same time, Mister Oppenheimer became chairman of the advisory committee to the United States Atomic Energy Commission.
For example, in terms of the atomic theory of matter, at the time at the turn of the Century, the understanding was that atoms were the most basic constituent of matter, meaning you couldn't break atoms up into anything smaller - that was it, you're done.
例如在原子理论中,在19，20世纪之交的时候,人们认为原子是,组成物质的最基本粒子,也就是说你不能,把原子再分割了,就这样了。
