本文评述了核能(衰变能、裂变能、聚变能)利用的现状和前景。
In this paper the progress and prospect of utilization of nuclear energy (decay, fission and fusion energy) are reviewed.
然后，它与它的伙伴们将会几乎在瞬间衰变为大批寿命更短的微粒子，其中有一些能被检测出来。
Both it and its companions would then decay almost instantly into a plethora of less fleeting bits, some of which could be detected.
这表明在指数衰变模型下，Rhett每分钟能获得约20次点击。
This says that in the exponential decay model (for this time range) I would have been getting about 20 hits per minute. And here you can see where my model breaks down.
科学家认为抗氧化剂（例如维生素C、E以及各种类胡萝卜素、锌等）能降低视网膜的氧化破坏，但是尚未有足够证据证明食物中的抗氧化剂能防止黄斑衰变。
Antioxidants (such as vitamin C, vitamin E, various types of carotenoids, and zinc) are thought to reduce oxidative damage to the retina.
如果这颗星星的外层能被核心的引力束缚住那么这个衰变即膨胀的过程就可能被减缓。
If the star's outer layers could be mixed into the core, that would slow the process of inflation down.
而K中介子能被任何质子衰变探测仪探测到，比如日本的超级神冈探测器(精度最高)。
And that kaon could be detected by any machine looking for proton decays, namely Japan's SuperKamiokande detector (pictured top).
你已经指出了在7个区块可能对抗细胞衰变，能举例吗？
You've identified seven particular areas of cellular decay that might be combated. Can you give examples?
“这些生物从一个我们从未想到的来源获取能量，”McKay惊叹，“南非的极端微生物细菌吃的是岩石里不稳定原子衰变时的放射能。”
"These creatures get their energy from sources we never imagined," McKay exclaims. "the South African extremophile bacteria are powered by the radioactive decay of unstable atoms in the rocks."
冰川期中的绝大部分所跨越的是这样一个时期，对于这一时期，没有任何元素能拥有一种恰如其分的衰变率。
Most of the Ice Age spans a period of time for which no element has as appropriate decay rate.
衰变辐射也能释放部分热量，这种热量被称为衰变热。
The decay radiation then deposits most of its energy in the fuel, and this is what is referred to as decay heat.
铯- 137的危害不像碘- 131那么大，但也能破坏DNA并诱发癌症。而且能在碘- 131已经衰变减弱到无害之后很久依然有危害。
It is not as harmful as iodine-131, but can still damage DNA and cause cancers long after iodine-131 has decayed to insignificance.
铯- 137的危害不像碘- 131那么大，但也能破坏DNA并诱发癌症。而且能在碘- 131已经衰变减弱到无害之后很久依然有危害。
