Uranium is usually extracted from ore that contains 1,000 or more parts per million of the element.

铀通常是从铀含量在百万分之一千以上（1000 ppm）的铀矿中提炼出来。

In order to determine the content of hydrocarbons and halohydrocarbons in uranium hexafluoride,the first step is to passivate the inlet system and ion source of mass-spectrometer.

了测定六氟化铀中烃和卤代烃的含量，首先要对进样系统和质谱计的离子源进行充分的钝化。样品必须全部汽化后方可通入质谱计，否则分馏效应将严重歪曲测量结果。

It is the 26th artificial element heavier than uranium to have been added to the periodic table.

它是第26个在元素周期表上由人工合成的超铀重原子。

To improve the flow rate of well is of importance to in-situ leaching of uranium in low permeable deposits.

提高钻孔涌水量是低渗透砂岩型铀矿床地浸开采的重要内容。

French Foreign Minister Bernard Kouchner rejected Iran's latest move on its uranium-enrichment efforts as a diplomatic pirouette.

法国外交部长贝尔纳·库什内拒绝伊朗最近在浓缩铀方面的举动，称这是外交周旋。

Then she found that pitchblende was more radioactive than uranium by itself.

玛丽注意到钍元素也是具有放射性的。

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？
