铷的读音

你需要两只激光器，一个无光的真空的空腔和一些铷- 85元素。

You need two lasers, a vacuous, light-free space and some Rubidium-85.

和GIOVE - A卫星携带的铷原子钟相比，这种原子钟具有更好的长期稳定性和精度。

The maser promises better long term stability and improved accuracy compared to the rubidium clock on board GIOVE-A.

随着光前驱和主波包通过第二组铷原子，科学家就可以对这两个光子成分的速度进行测量。

As the optical precursor and main wave packet traveled through a second group of rubidium atoms, the scientists took measurements on the speed of the two photon components.

So, for example, here we're showing rubidium and potassium and sodium plotted where we're plotting the frequency -- that's the frequency of that light that's coming into the metal versus the kinetic energy of the electron that's ejected from the surface of the metal.

让大家看来都是可以理解的事情,就是把不同金属的观测结果,画到一张图里面来，例如这里,我们展示的是钠，钾,铷的频率-这是照射金属的光的频率,和金属表面出射电子动能的关系。
