At low HNO3 concentration and dilution factor above 2, 0.1 mol/L DCH18C6/1-octanol extracts very little americium,plutonium and uranium.The distribution ratios of Am、Pu and U increase with the increase of HNO3 concentration in aqueous phase,and decrease with increasing of dilution factor of HLLW.The distribution ratio of extraction of Pu increases with the increase of extractant concentration.

研究结果表明，在低硝酸浓度和较大稀释倍数情况下，DCH18C6对镅、钚、铀的萃取分配比都比较小，并随着水相硝酸浓度的增大而增大，随着模拟高放废液稀释倍数的增大而减小，提高萃取剂浓度会增大四价钚的萃取。

The global pollution of the atmosphere with depleted uranium radioactive poison gas since 1991 is causing a global epidemic of chronic illnesses, which will contribute to extensive depopulation and ecological destruction.

全球污染大气层与贫化铀的放射性毒气自1991年以来，是导致全球流行的慢性疾病，这将有助於广泛的销毁和生态破坏。

The mining of uranium and enriched uranium have been abused, so that rapid deterioration of the Earth's environment.

对铀的开采已及浓缩铀的滥用，让地球的环境迅速恶化。

Thus generation and accumulation of uranium has intrinsic relationship in origin with pyrite and organic matters.

铀的富集和铀矿的形成可能与黄铁矿、油气、煤等有机质有密切的成因关系。

However, some of the minerals contain xenon isotope s unlike those usually produced by radioactive decay of uranium

然而，有些含氙同位素的矿物并非如此，是由铀的放射性衰变产生的。

A to approach Government Departments, keep them informed of the further development, and put forward recommendations for Government action, giving particular attention to the problem of securing a supply of uranium ore for the United States

第一， 去靠近政府部门，保持他们通告这更远的发展，并且快速介绍给政府行动，给以特有的注意这个问题上，为美国提供一种补给铀的矿石。

The price of uranium oxide, from which fuel for nuclear power plants is made, has risen from $7.25 a pound in 2001 to $47.25—a record in nominal terms.

可用以制造核电厂燃料的氧化铀的价格从2001年每磅7.25美元上涨至47.25美元，创下面值上的新高。

The influence of saccharomyces cerevisiae,seaweed, banyan leaves,firry cortex on adsorptive capacity of uranium was studied in order to seek cheap and effective biosorbents for environmental protection.

以保护环境为目的，以寻求廉价而有效的生物吸附材料为出发点，研究了啤酒酵母菌、北海海草、榕树叶、杉树皮等4种吸附剂对铀的吸附性能的影响。

Though the amount of gold in the seawater and bittern chemical resources is much low, the mechanism of extraction of gold from chloride solution by BODMAC was investigated here in order to achieve some theoretical fundamentals for extraction of gold from ocean resources.

虽然海水和苦卤中金的含量很低，我们在研究用BODMAC从苦卤中提铀的同时，也考察了BODMAC从氯化物中萃取金的机理。

The same type of centrifuges can be used to enrich weapons-grade uranium as those needed to make fuel for nuclear power plants.

同一类型的离心机可用于充实武器级铀的需要，使核电厂的燃料。
