铷

The rubidium lamps and cells are now obtainable only for replacement.

现在能够得到的铷光源和容器仅作备用。

But the effective size for rubidium atoms is 50 times smaller.

然而铷的有效截面却小上50倍。

Meanwhile, we take some improvement measure in order to improve the rubidium atomic frequency standard.

同时通过定量分析对电路实现提出了一系列优选方案， 从而使铷原子频标的性能得到改善。

A digital servo system for rubidium frequency standards was designed with microcontroller unit , ADC and DAC.
