铀的

Authors suggest that uranium ore formation occurred after the appearance of the above subsidiary tectonic units, and sandstone bodies of the Ⅱ,Ⅲ,Ⅳ,Ⅶ cycles, Shuixigou Group in the southern syncline, and sandstone bodies of the Ⅰ,Ⅱ,Ⅲ,Ⅴ cycles, Shuixigou Group, as well as sandstone bodies of Xiaoquangou Group in the northern monoclinal zone, they are ...

文章认为铀成矿作用发生在这些次级构造单元形成之后，且具有找矿前景的是南部向斜带水西沟群第Ⅱ、Ⅲ、Ⅴ、Ⅶ旋回砂体和北部单斜带水西沟群第Ⅰ、Ⅱ、Ⅲ、Ⅴ旋回砂体及小泉沟群砂体。从容矿层位连续性、分布面积、砂体特征及层间氧化带发育特征等成矿条件看，北部单斜带铀成矿条件和找矿前景均优于南部向斜带。

All the methods used now have a common technical difficulty: The presence of large amount of uranium makes unacceptable interferences to the determination of neptunium. A separation procedure is absolutely necessary to separate neptunium from uranium completely.

国内一直没有一个比较理想的准确、灵敏的方法，解决铀产品中微量镎的测定问题，主要原因是现有的方法存在一个共同的技术难点：常量的铀对微量镎的测定干扰很大，必须要将常量铀与微量镎定量分离。

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。

The uranium may be put into the reactor in the shape of rods, and the rods surrounded with a neutron-slower, or moderator

可以把铀做成棒状放在原子反应堆内，在铀棒的四周，围一层中子减速剂即节速剂。

A radioactive transuranic metallic element; discovered by bombarding uranium with helium atoms.

一种放射性的超铀金属元素，在用氦原子轰击铀时发现。

A synthetic transuranic element first produced by neutron irradiation of uranium in a thermonuclear explosion and now usually produced in the laboratory by irradiating plutonium and other elements.

锿一种人工合成超铀元素，在一次热核子反应的铀中子辐射中首次产生。

Recovered uranium and plutonium in mixed oxide fuel in nuclear power plants recycled to produce more energy, so that uranium resources ...

回收的 铀和钚可在核电厂混合氧化物燃料中再循环使用，以生产更多能量，从而使铀资源得到。。。

It can be used to determine accurately the abundant ratio in the uranium sample.

在铀样品的分析中，我们可以用稀释法测定铀

Electrochemical impedance spectroscopy results indicated that the dynamics of carbon steel electrode in uranyl nitrate is complex, in which intermediate compounds were formed onto the surface of carbon steel.

等效电路分析出现感抗和常相位角元件证实有中间化合物的生成，分析认为是在氧化铀／碳钢界面处形成了低价氧化铀。

The results showed that the adsorbing effects were affected by many factors, such as coal oxidation degree, coal type, pH value of solution, environmental temperature and initial concentration of uranyl ion.

结果表明，煤对铀酰离子(UO22+)的吸附作用受煤氧化程度、煤种、溶液pH值、环境温度和铀溶液初始浓度等因素影响。

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。
