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。

Owing to the fact that uranium is 106~107 higher than that of neptunium ,it is extremely difficult to remove uranium from neptunium without any loss of neptunium ,either from the theoretical calculation or from practical experience .

不论从理论计算上，还是从实际的工作经验上，两种待分离的元素在数量级上相差10~6～10~7，要将其中含量高的元素除去，而微量元素不损失是很困难的。

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。

The thesis focuses on the study of the reactions of hydroxyurea, a novel salt free agent, with uranium, neptunium and plutonium in order to investigate the possibilities of its application in the Purex process(1B) for uranium and plutonium separation.

本论文重点研究了一种新型无盐试剂—羟基脲与铀、镎、钚相互作用的化学，旨在研究这种新型无盐试剂在Purex流程铀、钚分离段(1B)中应用的可能性。

It is more practical to obtain one uranium product and one uraniumplutonium mixture product through partial separation of uranium and plutonium.

系统分析了用稀硝酸反萃分离萃入30％TBP／煤油中的铀钚的工艺，分析了各操作变量的影响，结果表明用稀硝酸反萃分离铀钚是可能的，铀钚部分分离得到有机相铀产品和水相铀钚混合物产品的工艺较为现实可行。

Study also shows that pitchblende coexists with pyrite in the cavities of organic fragments in uranium-bearing zones, and absorbed uranium α traces are found on the surface and around pyrite.
