铀

A gummy orange mixture of uranium oxides and silicates occurring naturally in the hydration and oxidation of pitchblende.

一种橙色粘性的铀氧化物和硅酸盐的混和物，由沥青油矿在水合作用和氧化作用下天然形成。

Marie:When the uranium and thorium are in the pitchblende,the reading is eight, but individually they only total four. Why,then, do they give out twice as much when they're in the pitchblende as they do when they're tested separately?

玛丽：当铀和钍包含在铀矿里的时候，读数是八，而分别测量后加起来只有四，那麼为什麼存在於铀矿中所产生的能量竟是单独产生能量之和的两倍？

Marie:When the uranium and thorium are in the pitchblende,the reading iseight, but individually they only total four. Why,then, do they give out twiceseparately?

玛丽：当铀和钍包含在铀矿里的时候，读数是八，而分别测量后加起来只有四，那么为什么存在于铀矿中所产生的能量竟是单独产生能量之和的两倍？

And oxidation of pitchblende.

一种橙色粘性的铀氧化物和硅酸盐的混和物，由沥青油矿在水合作用和氧化作用下天然形成。

The objection to the placer origin have centred around the softness of uranium compounds.

反对砂矿成因的论据主要是：铀的化合物不耐磨蚀。

He was to stop making plutonium as well as suspected work on uranium.

他也被要求停止钚以及铀等可疑项目。

However, the actual weight of uranium or plutonium in such a weapon is greater than this amount

可是，在一枚那样的核武器中，铀或钚的实际重量要比这个数字大得多。

Pyongyang has already closed one plutonium reactor, but there are now fears it may also be pursuing uranium enrichment.

平壤已经关闭了一个钚反应器，但是现在新的担忧是，他们会继续研究铀浓缩技术。

Iran says it is fiddling with uranium and plutonium to produce more electricity.

伊朗轻描淡写的说利用铀和钚可以更多发电。

It was found that these uranium alloys, especially uranium-zirconium alloys, showed high durability against powdering upon hydrogenation and had similar hydrogen desorption properties as uranium metal.

实验发现这几种铀合金具有优良的吸氢-释氢特性和较好的抗粉化性能。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
