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

介是所谓的基本一，且不能再分。

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

理论上，μ中微几乎能秒变称电中微。

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，它们产生比原更小的，如中和μ介。

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

电中微、μ中微和τ中微。

So it emits phased muon particles.

它阶段性放射出定相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：电中微、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.

它们可能是一个电和它的反物质等价物，一个正电，或者两个更重的轻，一个介和一个反介。

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

我们记录了 μ 像那时衰变的产物。

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。

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

电也有同的发现，它们有更重的兄弟姐妹， 称为 μ 介和 tau。

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

四年后，同使用云室， 他又在宇宙射线中发现了介。

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。琼斯教授在研讨上说，他找到了计算μ介质量的新方法。

Scientists used muons, a by-product of the cosmic rays constantly raining down on our planet, to image the interior of the pyramid.

科学家用μ介来描绘金字塔内部的情况，μ介是一种持续落到地球上的宇宙射线的副产品。

Measurements of weak interactions found that there are different kinds of neutrinos associated with the electron, muon, and tau.

弱相互作用的测量发现， 有不同种类的中微与电、μ 和 tau 相关。

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 个电只发射 85 个 μ 。

Topics that people use muons for range from fundamental constants of nature, basic symmetries, weak nucleon and nuclear interactions.

人们使用 μ 的主题范围从自然的基本常数、基本对称性、弱核和核相互作用。

Now the muon is an unstable particle.

现在 μ 是一个不稳定的。

According to the accepted rules of particle physics, such decays should yield as many muons as they do electrons.

根据公认的物理学规则，这种衰变应该产生与产生电一多的 μ 。

Krauth says just getting hold of the muons was tricky.

克劳斯说，仅仅掌握 μ 就很棘手。

Photons, carriers of the electromagnetic force, interact with electrons, muons and taus in identical ways.

光，电磁力的载体，以相同的方式与电、介和陶相互作用。
