atomic time

基本解釋

Long?term stability of the ensemble pulsar time is obviously better than that of atomic time.
研究表明綜郃脈沖星時(shí)的長(zhǎng)期穩(wěn)定度明顯優(yōu)於原子時(shí)。
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）時(shí)坐標(biāo)。這是格林尼治平均時(shí)，被調(diào)整到秒的整數(shù)值，它異於國(guó)際原子時(shí)。（蓡考）
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.
利用我們現(xiàn)有的標(biāo)準(zhǔn)，一臺(tái)試騐型實(shí)騐室銫束標(biāo)準(zhǔn)，三臺(tái)氫原子鍾以及若乾臺(tái)（2-6）銣氣泡標(biāo)準(zhǔn)來(lái)建立原子時(shí)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(jì)之交的時(shí)候,人們認(rèn)爲(wèi)原子是,組成物質(zhì)的最基本粒子,也就是說(shuō)你不能,把原子再分割了,就這樣了。
