1. The team prepares a beam of just one type, muon neutrinos, sending them from Cern to an underground laboratory at Gran Sasso in Italy to see how many show up as a different type, tau neutrinos.

   这个小组准备了一束单一类别的中微子即μ介子中微子并将它们由研究所射向位于意大利Gran Sasso地下的实验室来观察有多少变换了种类，τ介子中微子。

2. About 1% of the time the muon finds itself in the 2S state, where it can be excited to the 2P state by absorbing a photon from a laser pulse. The 2P state then decays with the emission of an X-ray.

   大约1%的时间，μ介子自已找到2S能级位置，这个位置上μ介子可以吸收来自激光的一个量子被激发到2P能级，随后发出X光，2P能级位置随之下降。
