铀转化

而当锆石凝结时，锆石里面的铀转化成铅。

And when Zircon crystallizes , the Uranium inside it begins to change into Lead .

利用高频感应加热装置分解矿样，提取的结构水和700℃的金属铀作用被转化成氢气。利用MM-602D型质谱计测量氢的同位素组成。

The samples were decomposed in a high frequency induction furnace and the released structural water was converted to hydrogen by reaction with metal uranium at 700 ℃ and the isotopic compositions of hydrogen were measured by mass spectrometer MM-602D .

在目前的反应堆里，一些铀238被转化成钚，作为一种用量较小的辅助燃料来使用，但绝大多数的钚都会剩下来，成为废料。

( A uranium bomb runs on more than 90 percent uranium 235 . ) In today 's reactors , some uranium 238 is converted to plutonium that is used as a small , supplemental fuel , but most of the plutonium is left behind as waste .

试验结果：铀收率为99.96%，铀的转化率为93.5%。

The recovery ratio of uranium is 99.96 % and the conversion ratio of uranium is 93.5 % .
