Some are exploring yet further fuel cycles—reacting deuterium nuclei to generate power, rather than just to test apparatus, for instance, or fusing lithium with protons.

一些正在探索更进一步的燃料循环——反应氘原子核以产生能量，而不是仅仅用于测试设备，例如， 或将锂与质子融合。

But instead of fusing two of these, as happens in the sun (yielding 4He and two protons), it fuses them one at a time with deuterium nuclei, to produce 4He and a proton.

但是它并没有像在太阳中那样融合其中的两个（产生 4He 和两个质子），而是一次将它们与氘核融合，产生 4He 和一个质子。
