The " Oh My God particle" detected more than 30 years ago was 320 exa-electron volts.

30 多年前探 " Oh-My-God" 能量为 320 埃电子伏特。

The event triggered 23 of the surface detectors, with a calculated energy of about 244 exa-electron volts.

该事件触发了 23 个表面探器，计算出能量为 244 电子伏特。

That would make the Amaterasu particle 244,000,000,000,000,000,000 electron volts.

这样，天照粒子能量就是 244,000,000,000,000 电子伏特。

For reference, 1 exa-electron volt equals 1 billion gigaelectron-volts, and 1 gigaelectron volt is 1 billion electron volts.

作为参考，1 埃电子伏特等于 10 亿千电子伏特，1 千电子伏特等于 10 亿电子伏特。

By comparison, the typical energy of an electron in the polar aurora is 40,000 electron volts, according to NASA.

比之下，根据美国国家航空航天局（NASA）数据，极地极光中电子典型能量为 40,000 电子伏特。

These particle energies are usually measured in units called electron volts.

这些粒子能量通常以称为电子伏特单位量。

The masses of the up and down quarks, they're a few MeV each.

上夸克和下夸克质量，它们各自大是几电子伏特。

So you add those up and you get something like 9 or 10 MeV.

所以你把这些加起来，得大910电子伏特。

So with germanium, that's about 0.75 electron volts.

所以对于锗，这个值大是0.75电子伏特。

In Rutherford's experiment, the alpha-particles had energies of millions of electron volts.

在卢瑟福实验中，α粒子具有数百万电子伏特能量。

The most  energetic remains the Oh-My-God particle, detected in 1991, which boasted an  energy of 320 exa-electron volts.

最具能量当属1991年发现“天哪粒子”，其能量高达320艾电子伏特。

The GZK limit for a  proton is 50 exa-electronvolts.

质子GZK极限是50艾电子伏特。

However, an extraordinarily violent object would be  required to produce a particle with hundreds of exa-electronvolts.

然而，要产生能量高达数百艾电子伏特粒子，需要一个极其猛烈天体。

The energy that an electron gains from an electric field of one volt is what is known as an electron volt.

电子从一伏特电场中获得能量称为电子伏特。

These rays vary in energy, spanning  from million electronvolts to over 50 exa-electronvolts, with the latter  known as extreme-energy cosmic rays.

这些射线能量各异， 从百万电子伏特超过50艾电子伏特不等，后者被称为极高能宇宙射线。

This particle could be decaying, thereby producing particles with energy levels  in the thousands of exa-electronvolts.

这一粒子可能正在衰变，从而产生能量高达数千艾电子伏特粒子。

A beam of protons was accelerated to a little over one giga electron volts, by far the highest energy ever attained by artificial acceleration.

一束质子被加速略高于十亿电子伏特，远超以往人工加速所能达最高能量。

John Matthews from the Telescope Array  project explains that the Milky Way can generate cosmic ray particles with energies ranging  from 0.1 to 10 exa-electronvolts.

望远镜阵列项目翰·马修斯解释说，银河系能够产生能量范围在0.110艾电子伏特之间宇宙射线粒子。

More recently, we have learned how to use electromagnetic fields to give particles energies of at first millions and then thousands of millions of electron volts.

最近，我们学会了如何使用电磁场为粒子提供最初数百万电子伏特和数亿电子伏特能量。

It suggests that particles with energy levels in the thousands of  exa-electronvolts might overcome collisions with the cosmic microwave background radiation  through some unknown mechanism.

这表明，能量高达数千艾电子伏特粒子可能通过某种未知机制，克服与宇宙微波背景辐射碰撞。
