Using a PET scan technology that he helped develop and partly owns.

使电子发射扫描技术，这个是博士协助开发的技术并拥有部分所有权。

Positrons are the antimatter counterparts to electrons.

电子是电子的反物质。

When electrons collide with the foil, positrons are formed in the flow.

当电子与金属箔相撞时，电子在流动中形成。

Next, a magnet comes into play and spreads positrons and electrons in different directions.

接下来，一个磁铁开始发挥，电子和电子分散到不同的方向。

A positron for example is just like an electron but it has positive charge.

如一个电子，就是一个电子，但是带有一个电荷。

And when an electron and a positron or a proton and antiproton meet, they annihilate.

当一个电子与电子相遇，或者一个质子与反质子相遇，它们就会抵消。

One possible explanation is that these excess positrons are a by-product of dark matter interactions.

这些多余的电子是暗物质间相互的副产物。

You wrote that article on the positron.

你写过关于电子的那篇文章。

The positron cannon is ready to fire, and you're safe.

电子炮已准备好开火 你安全了。

I'm sorry, we have a positron cannon?

抱歉 我们还有电子炮？

They used PET scans to look at the flow of oxygen and sugar in the brains.

他们使PET（电子发射断层扫描技术）扫描来观察大脑中氧气和糖分的流动。

Its new results show more positrons than expected.

最新观测结果显示，这些粒子带的电子要想象的多。

The positron cannon is ready to fire.

电子炮准备好了。

It begins to decay and emit positrons, aka, anti electrons.

它开始衰变并释放电子，也就是反电子。

The collision first forms a neutron, and then a positron.

碰撞首先生成一个中子，然后生成一个电子。

Oppenheimer's early research was devoted in particular to energy processes of subatomic particles, including electrons, positrons, and cosmic rays.

奥本海默早期的研究特别致力于亚原子粒子，包括电子、电子和宇宙射线的能量过程。

Thus, humanity recognized the positron, a positively charged copy of the electron.

因此，人类认识到了电子，一种带电的电子拷贝。

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，一个电子，或者两个更重的轻子，一个介子和一个反介子。

Within the limits of accuracy of the experiment, positron spin-flipping seems to happen at the same frequency as electron spin-flipping.

在实验精度可以达到的范围内，电子的自旋反转似乎与电子的自旋反转发生在同一微波频率上。

The positron then immediately finds an electron, the two annihilate making a tiny flash of light, a photon.

电子马上找到一个电子，这两个湮灭时产生光子的微小闪光。
