In order to construct nuclear weapons, you need to have researched the Rocketry and Fission technologies, and have access to a source of Uranium, which is revealed by the Physics tech.

要建造ICBM你必须研究火箭和核裂变技术，而且必须要有研究了物理学后才能发现的资源：铀。

Against the backdrop of growing tensions in the Middle East and nuclear "saber rattling" elsewhere in Asia, the authors point out that een the smallest nuclear powers today and in the near future may hae as many as 50 or more Hiroshima-size (15 kiloton) weapons in their arsenals; all told, about 40 countries possess enough plutonium and/or uranium to construct substantial nuclear arsenals.

在中东紧张局势加剧和亚洲核威慑的背景下，作者指出，当今或近期核力量最小的国家，在他们的兵工厂里也有相当于50甚至更多倍广岛原子弹（15千吨TNT当量）威力的核武器；总共大约有40个国家拥有足够的钚和/或铀制造大量的核武器。

Contaminant cations such as calcium,magnesium,barium,strontium,and radium and anions such as fluoride ,nitrate,fulvates,humates,arsenate,selenate,chromate ,and anioic complexs of uranium can be removed from water by using ion exchange or adsoption onto activiated alumina.

具有污染能力的像Ca，Mg，Ba，Sr，Ra的阳离子，和像氟化物，硝化物，黄酸物，腐质酸物，砷酸盐，硒酸盐和铬酸盐的负离子以及像铀一样的负离子复合物可以通过离子交换和离子吸附从水中排除。

Iranian Foreign Minister Manouchehr Mottaki said his country will not send its partly enriched uranium abroad to be turned into material for medical research, but added that Tehran might allow its nuclear material to be reprocessed inside Iran, the semiofficial ISNA news agency reported.

据半官方的伊朗学生通讯社报道，伊朗外交部长Manouchehr Mottaki说，他的国家不会将其丰富的铀材料输往国外以被用于医疗研究的材料，但补充说德黑兰可能允许其核材料在伊朗内部进行再加工。

The enrichment of minerals such as siderite and pyrite, which are sensitive to geochemical environment, in the transitional zone indicates that the geochemical environment is neutral-acidic and reductive and is propitious to the precipitation of uranium.

过渡带中菱铁矿(FeCO3)和黄铁矿(FeS2)等对地球化学环境敏感的矿物的富集，指示了有利于铀成矿的中性-弱酸性、还原的地球化学环境。

If the output used for feedback is programmed to another skew position, then the whole tU matrix will shift with respect to REF.

如果输出的反馈使用的编程到另一个位置偏差，那么整个吨铀矩阵将转移至REF方面。

China may snap up all the available uranium over the next few years.

中国可能折断了所有可用的铀在未来几年。

Academic achievement:(1) early study of the electromagnetic wave transmitting and receiving;(2) found that there is penetration of uranium weak penetration of the α and β two kinds of radiation;(3) and Soddy worked together to propose release of radioactive atoms can be α or β atom into another element.

学术成就：（1）早年研究电磁波的发射和接收；（2）发现铀中有穿透力弱的α和穿透力强的β两种辐射；（3）和索迪合作提出放射性原子可以通过放出α或β变成另一种元素的原子。

Stainless steel had a good antic-corrosive performance in alkalic solution and sodium carbonate containing uranium solution.
