1·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.
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。
2·A light beam shot through a blob of rubidium atoms can directly and reliably measure the size and orientation of a magnetic field, a team of physicists reports in the Sept. 13 Physical Review a.
9月13日，据一个物理学家小组在物理学评测A中的报道，一束光照射过一团铷原子就可以直接可靠地测量出一个磁场的大小和方向。
3·Most famously, uranium-238 decays into lead-206 with a half life of 4.5 billion years, though radioactive rubidium and samarium are also useful for dating things billions of years old.
最为有名的就是铀- 238衰变为铅- 206的半衰期为45亿年，当然放射性铷和钐也同样对测算几十亿年前的物体的年龄很有用。
4·Dr Steinhauer and his colleagues created a condensate out of a gas of rubidium atoms held in a magnetic trap.
Steinhauer博士和同事从盛在磁圈里的铷原子气体中制出冷凝物。
5·You need two lasers, a vacuous, light-free space and some Rubidium-85.
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。
