铀

Since the United States has made similar demands of Brazil and Iran, an LEU compromise with North Korea would have to be part of a larger policy shift in Washington.

自从美国对巴西和伊朗提出了相同的要求，对于与协商后朝鲜取得一个低浓度铀浓缩计划的折中方案可能成为美国政府大规模政策转变的一部分。

After four years' hard work and refinement of tons of pitchblende, Marie and her hus-band at last saw the dim blue light of the new element -- radium.

经过四年的艰苦工作，提炼了成吨的沥青铀矿，玛丽和她的丈夫终于看到了新元素——铀发出的微弱的蓝光。

So are electronic copies of detailed, e- mailable designs for a uranium-enrichment plant.

还有那些为富铀工厂设计的详细的能用电子邮件传输的电子拷贝。

A uranium isotope with mass number 235; capable of sustaining chain reactions.

铀的同位素，原子质量数为，能进行持续的连锁反应。

It could even be at Natanz, Iran's enrichment plant, says Meier.

甚至可以是纳坦兹，或者伊朗的铀浓缩工厂。

Comprehensive analysis shows that it has good petential for uranium metallization. It is the key targe layer in southern Songliao basin.

综合分析结果显示，该组具有较好的铀成矿潜力，是松辽盆地南部找铀矿的主攻目的层位。

They provide not only the migration pathway for uranium metallogenetic fluids, but also the space for uranium deposition.

在吐哈盆地和鄂尔多斯盆地的勘查实践发现，结构和规模适中的大型骨架砂体是砂岩型铀矿的储层，它不仅能提供铀成矿流体的运移空间，同时也为铀矿的储存提供了空间。

The mineralizer of CO〓 and S was derived from both stratigraphy and deep source.

降压沸腾引起的快速共沉淀是铀成矿的主要机理。

In principle all elements from boron to uranium can be determined, and trace element analysis and the determination of minor and major element concentrations can be performed on the same sample.

从原理上来说，可以测定从铍到铀的所有元素，在同一样品中可以同时进行痕量元素分析和次成分和主成分元素浓度的测定。

In this paper,effect of uranium substance on the mudstone pyrogenation was studied by hydrous pyrolysis.

采用加水热模拟实验方法，考察了含铀物质对泥岩样品热解生烃产物的影响。

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。
