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

这些粒子能量称为电子的单位测量。

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

在卢瑟福的实验中，α粒子具有数百电子的能量。

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。

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电子和数亿电子的能量。

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，要么证明希格斯粒子具有130—150吉电子的质量，要么证明只要它确实存在，那么它必定要更重一些。
