铀的

One scientist noticed a mark on a photographic plate that was near uranium.

当时，有一个科学家注意到，在一个靠近放置铀元素地方的照相底板上多出了一个记号，他不知道这个记号是怎样会产生的。

The present project intends to develop a new compound only containing CHON, which can extract U, Pu and the minor actinides together form the acidic media to integrate the reprocessing.

本课题旨在寻找一种新的只含CHON的化合物，能够从酸性介质中同时萃取铀、钚和次锕系元素，实现后处理一体化。

Subsequent redistribution of uranium in provinces formed at that time most probably resulted from orogenic processes and associated anatexis.

铀在成矿区内的重新分布，最可能是由于造山作用及伴随的泾熔作用。

The determination of free acidity with the presence of rare ,uranium,thorium andiron,etc is studied.

研究了在稀土，铀，钍及铁等元素存在下自由酸度的测定，标准回收完全，适用于稀土料液自由酸度的测定

The main paragenetic minerales are: uranophane, uranium blacks, autunite, meta-torbernite, microquartz, quartz, ankerite, calcite, fluorite, hydromica, pyrite, galena, sphalerite, and chalcopyrite.

矿化作用共可分为八个阶段，同位素研究结果表明，矿床中的铀主要来自岩浆溶液，部分轴来自围岩——侏罗系长石石英砂岩。沥青铀矿的同位素年龄为108—109百万年。

In this paper, we introduce an experimental set-up, which is rebuilt on the basis of typeDMP-450 coater and applied to AVLIS(atomic vapour laser isotope separation).

1引言激光原子法分离铀同位素是目前世界上一些国家积极探索的、有前途的新课题。

All uranium atoms do not have the same atomic weight.

所有的铀原子并非都有相同的原子量。

Some companies have holdings in multiple uranium districts, which may also become recognized as a wise decision by their management.

一些公司已拥有多种铀区，它也可能成为公认的一个明智的决定，由他们管理。

IAEA verified this level of enrichment is well below what's needed to build a nuclear bomb.

国际原子能机构证实这一级别的铀浓缩远远低于所需要的制造核弹。

He fell in love with Irène Curie, and soon after their marriage in 1926 they both changed their surnames to Joliot-Curie.

先前他曾在居里实验室和妻子何泽慧合作，发现了铀核的三分裂和四分裂现象。

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。
