〔物〕核聚变
In nuclear fusion, a pair of light nuclei unite (or fuse) together, form a nucleus of a heavier atom.
在核聚变的情况下，一对轻核合并（或聚合）在一起，形成一个较重的原子核。
The star used to be like the sun, a "main sequence" star that burns hydrogen by nuclear fusion, producing helium.
这颗恒星曾和太阳一样，是颗“主序星”（“mainsequence”）。它通过核聚变燃烧氢，从而产生氦。
Massive stars normally die when they run out of material to sustain nuclear fusion, and all that"s left in their cores is inert iron.
大质量恒星死亡时，它们通常运行的材料进行维持核聚变，以及所有在其核心的左边是惰性铁。
It"s easy to see why: nuclear fusion powers the sun, and it holds out the possibility of near-limitless electricity, without pollution.
很容易知道原因：核聚变为太阳提供能量，也为一种近乎无限的无污染的电提供了可能。
Quantum tunneling is involved in many physical processes, such as radioactive decay and the nuclear fusion that takes place in the Sun.
量子隧穿发生在许多的物理过程中，比如说放射性衰变和太阳上发生的核聚变。
But to effectively use the energy released by nuclear fusion, nuclear fusion must be able to reasonably control the speed and scale.
但要想有效利用核聚变释放的能量，必须能够合理地控制核聚变的速度和规模。
A large amount of nuclear energy is produced when a heavy nucleus splits in two light nuclei join to form a heavier nucleus(nuclear fusion).
当一个重核子分裂成两个结合在一起形成一个更重核子的轻核子时，释放巨大的能量（核聚变）。
Brown dwarfs are not quite big hot enough to ignites the nuclear- fusion reaction that would make them shine as full- fledged stars .
棕矮星的体积还不够大，热度也不够高，还不足以引发核聚变反应；棕矮星必须经过此一反应才会发光，成为成熟的星星。
The stars form when gas in the cloud condenses under its own gravity and becomes packed enough to ignite nuclear fusion.
星云中的气体在它的重力下凝聚形成新星，新星变得足够满以避免核聚变。
Well, the only way that we might survive -- the quality of life is at stake here is nuclear fusion.
好吧，我们可能生存下来的唯一办法，在此生活质量处于险境，是核聚变。
