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

30 多年前探测到的 " Oh-My-God" 的能量为 320 埃电子。

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 个表面探测器，计算出的能量约为 244 电子。

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

这样，天照粒子的能量就是 244,000,000,000,000 电子。

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 埃电子等于 10 亿兆电子，1 兆电子等于 10 亿电子。

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

比之下，根美国国家航空航天局（NASA）的数，光中电子的典型能量为 40,000 电子。

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

这些粒子能量通常以称为电子的单位测量。

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

上夸克和下夸克的质量，它们各自大约是几兆电子。

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

所以你把这些加起来，得到大约9到10兆电子。

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

所以对于锗，这个值大约是0.75电子。

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

在卢瑟福的实验中，α粒子具有数百万电子的能量。

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

最具能量的当属1991年发现的“天哪粒子”，其能量高达320艾电子。

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

质子的GZK限是50艾电子。

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的粒子，需要一个其猛烈的天体。

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

电子从一电场中获得的能量称为电子。

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

这些射线的能量各异， 从百万电子到超过50艾电子不等，后者被称为高能宇宙射线。

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艾电子的粒子。

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

一束质子被加速到略高于十亿电子，远超以往人工加速所能达到的最高能量。

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.

望远镜阵列项目的约翰·马修斯解释说，银河系能够产生能量范围在0.1到10艾电子之间的宇宙射线粒子。

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和数亿电子的能量。

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，能量高达数艾电子的粒子可能通过某种未知机制，克服与宇宙微波背景辐射的碰撞。
