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.
利用我們現(xiàn)有的標準，一臺試驗型實驗室銫束標準，三臺氫原子鐘以及若干臺（2-6）銣氣泡標準來建立原子時尺度。

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.
例如在原子理論中,在19，20世紀之交的時候,人們認為原子是,組成物質(zhì)的最基本粒子,也就是說你不能,把原子再分割了,就這樣了。
