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

子是所谓的基本粒子之一，且不能再分。

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

电子中微子、μ中微子和τ中微子。

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

理论上，μ中微子几乎能秒变称电子中微子。

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，它们会原子更小的粒子，如中子和μ子。

So it emits phased muon particles.

它会阶段性放相μ子。

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

看！有三味中微子：电子中微子、τ中微子、μ中微子。

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

它们可能是一个电子和它的反物质等价物，一个正电子，或者两个更重的轻子，一个子和一个反子。

Krauth says just getting hold of the muons was tricky.

克劳思说，仅仅是获取这些μ子就很有难度。

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子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子像那样旋转时的衰变物。

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

正是这个μ子，而非中微子本身，在探测器中闪现。

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

μ子是亚原子粒子，类似于电子但质量大得多。

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

μ子就像是电子的加大版。

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

电子也有同样的发现，它们有更重的兄弟姐妹， 称为 μ 子和 tau。

The muons last for only two microseconds.

μ子只能存在两微秒。

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， 他又在宇宙线中发现了子。

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

这一现象沿着μ子粒子穿越冰层的整个路径持续发。

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 个电子只发 85 个 μ 子。

It's called the Scan Project using muons.

这被称为使用缪子的扫描项目。

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

好了，听听这个。琼斯教授在研讨会上说，他找到了计算μ子质量的新方法。
