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 埃电子伏等于 10 亿千兆电子伏，1 千兆电子伏等于 10 亿电子伏。

Their goal is to have enough data by the end of the year either to say definitely that the Higgs has a mass of 130-150 gigaelectron-volts, or that if it exists at all, then it must be heavier than that.

他们的目标是到今年年末获得足够的数据，么证明希格斯粒子具有130—150吉电子伏的质量，么证明确实存在，那么必定更重一些。

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

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

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 电子伏。

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

30 多年前到的 " Oh-My-God" 的能量为 320 埃电子伏。

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，计算出的能量约为 244 电子伏。

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伏的能量。

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

上夸克和下夸克的质量，们各自大约是几兆电子伏。

But by working backwards, the researchers were able to tentatively conclude that the neutrino that generated it was packing something like 220 petaelectron-volts of energy—in layman's terms, about as much as a ping-pong ball dropped from a height of a metre.

然而，通过反向推理， 研究人员初步得出结论， 产生该μ子的中微子携带着约220拍电子伏的能量——用通俗的话说，这能量大约相当于一个乒乓球从一米高处落下时所具有的能量。

Silicon's band gap is just a little higher, 1.1 electron volts, but you have an exponential dependence on the number of carriers that are present that can induce those errors

硅的禁带宽度略高一些，为1.1电子伏，但你对能引起这些错误的载流子数量有着指数级的依赖关系。

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伏，远超以往人工加速所能达到的最高能量。

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， 从百万电子伏到超过50艾电子伏不等，后者被称为极高能宇宙射线。

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10兆电子伏。

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

所以对于锗，这个值大约是0.75电子伏。

This tiny single particle carried an  astonishing energy of over 240 exa-electronvolts, equivalent to the kinetic energy of a high-speed  baseball or the impact of dropping a lead brick on your toes from waist height.

这微小单粒子携带着惊人的240多艾电子伏能量，相当于一颗高速棒球的动能， 或从腰部高度掉落的铅块砸在脚趾上的冲击力。

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和数亿电子伏的能量。

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的单位量。

So a proton is made of three quarks whose masses add up to about 10 MeV, and a whole bunch of massless gluons, and somehow it still has 938 MeV as its mass.

所以一个质子由三个夸克组成， 这些夸克的质量加起来约为10兆电子伏，还有一堆无质量的胶子，但的质量仍然达到了938兆电子伏。

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

然而，产生能量高达数百艾电子伏的粒子，需一个极其猛烈的天体。

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。
