铀

The interlayer oxidized zone and the concentration of uranium has the typical characters of low temperature geochemical processes. Interlayer oxidized zone can be defined from the bedrock to horizon C under hypergene weathering by such parameters as chemical metamorphosing、index of chemical weathering and index of mineral chemical differentiation.(2)Major elements can be divided into sensitive group、 active、 weak active and inert groups according to chemical metamorphosing parameter and fractional migration potential. For major elements of multivalent in the active group( Fe_2O_3、 FeO) and U, the migration and concentration trend in interlayer oxidized zone is apparent.

层间氧化带形成和铀富集成矿是地下水在低温、常压、开放体系、非平衡状态对围岩长期作用结果，元素含量及其有关地球化学参数在氧化带不同亚带中表现出一定的变化和分布规律，除Fe_2O_3、FeO、Fe_2O_3／FeO外其它元素含量及其参数只在统计学上呈现规律性变化，而不具分带意义，具有典型的低温地球化学作用特点；利用风化作用化学蚀变参数PC值、化学风化指数ICA和矿物化学分异指数ICV将层间氧化带作用界定于表生风化作用的基岩到母质层阶段。

In order to study the migrating rule of contaminants, a steady two dimentional mathematical model is adopted to simulate the groundwater flow field around the uranium miffing dam, and the model is solved with Galerkin finite element method.

为了研究污染物在地下水中的迁移规律，采用二维稳定流数学模型对铀尾矿库周围地下水流场进行概化，并用Galerkin有限元法对模型进行了求解。

Iran has become even noisier about its desire to go on enriching uranium.

伊拉克甚至闹着渴望要继续他们的铀浓缩。

Recently, the National Development and Reform Commission has approved the China Petroleum Fuel Oil Company's 300,000 tons Oil off-loading Jetty Project in Ningbo Daxie Development Zone of the Ningbo-Zhoushan Port.

中国核电产业的快速发展，将为中哈在天然铀等相关领域合作提供广阔的空间。

The project plans to build a jetty with berthing capacity of 300,000 tons for crude oil loading / off-loading and releavant facilities (the port and hydraulic engineering construction also take the larger oil tanker into consideration), its designed transferring capacity is 120 million tons per year.

中哈两个邻国，一个是核电发展最快，未来装机容量最大的国家，一个是铀资源丰富的国家，这种天造之合必然会为中哈的经贸合作开辟一个油气之外的新领域。

Avalon Rare Metals, for example, owns a rare-metals property at Thor Lake in the Northwest Territories. Ucore Uranium, based in Halifax, has a project in southeastern Alaska. VMS Ventures optioned a uranium and rare-earth property in Manitoba. Billingsley's company, Great West Mineral Group of Saskatoon, owns the Hoidas Lake project on the northern fringe of Saskatchewan.

例如，在西北地区托尔湖拥有稀有金属矿的阿瓦隆稀有金属公司；坐落于哈利法克斯，在阿拉斯加东南部有项目的铀核铀矿公司；握有曼尼托巴的铀矿和稀土矿购买权的VMS投资公司；还有比利斯利的公司，在萨斯喀彻温省西北边辉达斯湖有项目的大西部矿业集团公司。

Its CANDU reactors were once thought superior because they could be refuelled without shutting down.

它的重水铀反应堆可以在不关闭的情况下进行燃料补给，一度被认为世界领先。

Spent fuel from NPPs is planned to be reprocessed in China to make full utilization of uranium.

废燃料的核电站计划在中国再加工，使铀的充分利用。

Suspend the enrichment and reprocessing activities and we'll talk and once we talk there are all sorts of good things that can happen.

同延缓铀浓缩和回收活动一样，我们要谈的和我们曾经谈到的都会产生各种各样有利的影响。

Inevitably India will now be able to direct more of its scarcer domestic uranium to its military needs.

不可避免的，印度目前将能够将其国内为数不多的铀直接用于军事用途了。
