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

子能量通常以称为电子伏特的单位测量。

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

在卢瑟福的实验中，α子具有数百电子伏特的能量。

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

电子从一伏特电场中获得的能量称为电子伏特。

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.

近，我们学会了如何使用电磁场为子提供初数百电子伏特和数亿电子伏特的能量。

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