1·However, in muonic hydrogen the Lamb shift is much more dependent on the proton radius because the much heavier muon spends more time very near to – and often within – the proton itself.
无论如何，μ介子氢的兰姆位移更加依赖于质子的半径，因为相对电子更加重的μ介子靠近或者时不时进入质子本身的时间也更多。
2·Neutrinos are known to switch back and forth between their three observed types (electron, muon and tau neutrinos), and OPERA was originally designed to detect these shifts.
中微子可以在我们所知的3个已经观察到的类型（电子，μ介子和τ中微子）之间来回切换，OPERA最初的设计是用来检测这些切换的。
3·A discovery that neutrinos, virtually massless particles, convert into other forms known as muon and tau before they leave the sun, solving a 40-year-old mystery.
发现中微子(几乎是无质量的粒子)在离开太阳之前可转化介子，解开了一个40年的谜。
