A muon is one of the so-called elementary particles, one with no smaller parts.

是所谓的基本粒之一，且不能再分。

Neutrinos come in three flavors, called electron, muon and tau.

中微、μ中微和τ中微。

Theory said that a muon neutrino could almost instantly change into an electron neutrino.

理论上，μ中微几乎能秒变称中微。

When they do, they create particles that are smaller than atoms, such as neutrons and muons.

当它们穿过地球大气层时，它们会产生比原更小的粒，如中和μ。

So it emits phased muon particles.

它会阶段性放射出定相μ。

See, there are three different kinds or flavors of neutrinos: electron neutrinos, tau neutrinos, and muon neutrinos.

看！有三味中微：中微、τ中微、μ中微。

These may be an electron and its antimatter equivalent, a positron, or two heavier leptons, a muon and an antimuon.

它们可能是一和它的反物质等价物，一正，或者两更重的轻，一和一反。

Krauth says just getting hold of the muons was tricky.

克劳思说，仅仅是获取这些μ就很有难度。

We measure the difference between the spin direction and the direction the muons were going.

我们测量自旋方向与μ运动方向之间的差异。

We record the products of the muon decays when they spin around like that.

我们记录当μ像那样旋转时的衰变产物。

It was that muon, rather than the neutrino itself, that flashed through the detector.

正是这μ，而非中微本身，在探测器中闪现。

Muons are subatomic particles, similar to electrons but much heavier.

μ是亚原粒，类似于但质量大得多。

Muons are just the plus-size version of an electron.

μ就像是的加大版。

The same was found for electrons, which have heavier siblings called the muon and the tau.

也有同样的发现，它们有更重的兄弟姐妹， 称为 μ 和 tau。

The muons last for only two microseconds.

μ只能存在两微秒。

Four years later, also using a cloud chamber, he discovered the muon, again in cosmic rays.

四年后，同样使用云室， 他又在宇宙射线中发现了。

This is happening all along the path  the muon takes through the ice.

这一现象沿着μ粒穿越冰层的整路径持续发生。

Instead, Dr Patel's team found that only 85 muons were emitted for every 100 electrons.

相反，帕特尔博士的团队发现每 100 只发射 85 μ 。

It's called the Scan Project using muons.

这被称为使用缪的扫描项目。

Okay. Get this. " Professor Jones told the symposium he had a new method " for calculating the mass of a muon.

好了，听听这。琼斯教授在研讨会上说，他找到了计算μ质量的新方法。
