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

介是所谓的基本粒之一，且不能再分。

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.

当它们球大气层时，它们会产生比原更小的粒，如中μ介。

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

中微、μ中微τ中微。

So it emits phased muon particles.

它会阶段性放射出定相μ介。

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.

它们可能是一个它的反物质等价物，一个正，或者两个更重的轻，一个介一个反介。

Well, let's assume for a second that we can represent a muon by this gyroscope.

好吧，假设我们能用这个陀螺仪来表示一个μ。

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。

The muons last for only two microseconds.

μ只能存在两微秒。

(laughs) Have you ever heard of a muon?

（笑）你听说μ吗？

Another example is neutrinos, and then another example is the muon.

另一个例是中微，另一个例是μ。

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

正是这个μ，而非中微本身，在探测器中闪现。

And what's up with the recent results on muon precession frequency?

近期关于μ进动频率的研究结果有何新发现？

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 介 tau。

Now the muon is an unstable particle.

现在，μ是一种不稳定的粒。

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。

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介。

Such interactions give rise to muons, which manifest as flashes of light inside the detector sensors.

这样的相互作用会产生μ，表现为探测器传感器内的光闪。

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介质量的新方法。
