以氨水分子中的氮原子的振动频率为基础的原子钟。

Congreve's clock is particularly interesting from the point of view of the history of the development of precision clocks because it represents a very early conscious attempt at a clock whose oscillator is as free as possible from the influence of the escapement.

康格里夫的时钟是特别有趣的观点的发展史上的高精度原子钟，因为它很早就意识到企图时钟振荡器的自由尽可能的影响逃逸。

Home-made hydrogen masers are measured and the result are analyzed in this paper.

As a note of interest that standard was more than acceptable for certified COSC chronometers in the 1960s, but most people today expect better, having been spoilt by the standards of their thermo-compensated, atomic clock adjusted quartz watches.

作为说明的利益标准超过可以接受的认证COSC计时器在20世纪60年代，但大多数人预计今天更好，被宠坏了的标准，他们的热补偿，原子钟调整石英手表。
