So it emits phased muon particles.

它会阶段性放射出定相μ。

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

微、μ微和τ微。

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。

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

理论上，μ微几乎能秒变称微。

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，它们会产比原更小的粒，如和μ。

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

看！有三味微：微、τ微、μ微。

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

它们可能是一个和它的反物质等价物，一个正，或者两个更重的轻，一个和一个反。

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。

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， 他又在宇宙射线发现了。

This would act more strongly on muons than it does on electrons.

这对 μ 的作用比对的作用更强。

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

我们测量自旋方向和 μ 行进方向之间的差异。

Next they bathe those ions in laser light, hoping to bump the muons up to a higher-energy but unstable state.

接下来， 他们将这些离沐浴在激光，希望将 μ 提升到更高能量但不稳定的状态。

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质量的新方法。

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

根据公认的粒物理学规则，这种衰变应该产与产一样多的 μ 。

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来描绘金字塔内部的情况，μ是一种持续落到地球上的宇宙射线的副产品。

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 个只发射 85 个 μ 。

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， 有不同种类的微与、μ 和 tau 相关。

Now the muon is an unstable particle.

现在 μ 是一个不稳定的粒。

The muons last for only two microseconds.

只持续两微秒。

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

我们记录了 μ 像那样旋转时衰变的产物。
