铀

Technetium is a widely concerned element in spent fuel reprocessing because of its high fission yield and complex behaviors which may effect the separation of uranium and plutonium.

锝是乏燃料后处理工艺中广泛关注的元素，因为其裂变产额高，行为复杂，对铀钚分离工艺过程的影响很大。

For close coordination and continuous product development to meet the customers needs, I have launched a series of the Division for surface mount MELF resistors, also known as wafer resistance, columnar resistance or non-lead resistance and so on, including the ultra-sophisticated, ultra-low temperature coefficient of RJM series, ultra-high resistance, high operating voltage of the RGM uranium metal film resistors.

为紧密配合和持续满足用户产品开发需要，我司推出了一系列用於表面贴装的 MELF 系列电阻，也称为晶圆电阻、柱状电阻或无引线电阻等，其中包括超高精密，超低温度系数的 RJM 系列，超高阻值，超高工作电压的 RGM 金属铀膜电阻器。

Now the Curies became interested in the strange behavior of a rare metal , uranium.

居里夫妇开始对一种稀有金属——铀的特性产生了浓厚的兴趣。

In 1898, the Curies obtained a new element, whose radioactivity was several million times stronger than that of uranium.

1898年，居里夫妇获得了一种新元素，它的放射性比铀强几百万倍。

The matter that the Curies had discovered was radium. It looked like ordinary salt, but was one million times more radioactive than uranium.

居里夫妇所发现的物质就是镭，看起来它就像普通的食盐一样，而它的放射性却铀要大一百万倍。

Chemical compounds and mixtures containing uranium and thorium are active in direct proportion to the amount of these metals contained in them.

含铀和钍的化合物和混合物活跃的程度与这些化合物和混合物中这两种金属的含量直接相关。

I found in this way that of the other elements known, only the cornpounds of thorium behave like the compounds of uranium.

于是我发现在其他所有已知元素中，只有针化合物才有像铀化合物一样的特性。

I measured the activity of a number of minerals; all of then~ that appear to be radioactive always contain uranium or thorium.

我测量了一些矿物的活性，所有显示放射性的物质均含有铀和针。

Radioactivity is the energy given off by rays from a few unstable elements such as uranium and thorium.

放射性是某些不稳定元素如铀和钍的射线放射出来的能量。

The produced thorium was radiochemically separated from the mixture of uranium and its reaction products.

用快速放射化学分离技术从铀及其反应产物的混合物中分离出Th同位素。

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。
