查询词典 enriched uranium

Few believe the tales Iranian officials have spun since the first news, in 2002, of their covert efforts to enrich uranium—usable for civilian nuclear reactors, but abusable at high enrichment for making weapons.

没人相信伊朗官员编的鬼话——2002年伊朗官员第一次公开宣称，他们的秘密铀浓缩活动仅仅是为民用核反应堆提供原料（高纯度铀可用于制造核弹）。

Few believe the tales Iranian officials have spun since the first news, in 2002, of their covert efforts to enrich uranium—usable for civilian nuclear reactors, but abusable at high enrichment for making weapons.

自从2002年伊朗官方就开始制造假新闻，几乎没有人会相信伊朗官方杜撰出来的，用来掩饰他们浓缩铀的秘密努力的故事。这些铀可用于民用核反应堆，但不可用于高度浓缩来制造核武器。

Efforts to persuade countries to forgo uranium enrichment and plutonium reprocessing (usable but not vital in civilian power programmes, but abusable for bomb-making) have sometimes backfired.

让那些国家放弃铀浓缩与钚回收（虽然很有用，但对关乎国计民生的能源体系并非重要，但却对于制造炸弹却意义非凡）有时会事与愿违。

Some problems of determining uranium isotope abundance by MAT-260 mass tpectrometer, especially, the influence factors on precision and accuracy are di-acussed. NBS standard samples are used for calibrating the acquisited data.

本报告介绍用MAT-260型质谱计测定铀同位素丰度，着重探讨了影响数据精确度的因素，并采用美国国家标准局样品对测得的数据进行校正，以保证其较高的准确度。

Turkish Foreign Minister Ahmet Davutoglu says his country is ready to play an intermediary role in a uranium exchange program.

土耳其外交部长达武特奥卢说，土耳其已准备好在伊朗的铀交换项目中充当中介人。

It indicated that the amidoxime functionalized fiber had large adsorption capacity and high selectivity for uranium.

由对UO2(上标 2+)、Mg(上标 2+)、Ca(上标 2+)3种离子的吸附数据可知，铀／镁、铀／钙的选择性系数分别为20.26和4.01，表明该偕胺肟基纤维对铀具有较强的吸附选择性。

This paper analyses the occurrence characteristics and formation conditions for uranium deposits within calderas and brecciated complexes of some granites in China and foreign countries .

本文分析了国内外若干产于花岗岩中破火山口及角砾杂岩内的铀矿床产出特征及形成条件，提出今后应在花岗岩区叠加的火山活动中心，注意寻找角砾杂岩型的铀矿，并把它作为花岗岩中铀矿找矿的新方向予以积极探索。

The organics and impregnations of uranium are everywhere coextensive.

有机物和铀的浸染到处是共同延伸的。

Vanadium mainly exists as independent minerals or in clay minerals in the form of isomorphism, with a small amount absorbed by clay minerals and limonite. Nickel mainly exists as independent minerals. Molybdenum occurs as colloidal sulfides with carbon, sulfur and clay, and forms molybdenite through thermal metamorphism. Uranium is unevenly scattered in collophanite and carbonaceous_argillaceous materials in the form of isomorphism or adsorption. REE mainly occur in collophanite in the form of isomorphism. Copper, lead and zinc chiefly exist in sulfides or sulfo_arsenides and are concentrated in the metallic layer.

钒或以独立矿物存在，或以类质同象赋存在粘土矿物中；镍主要以独立矿物存在；钼主要与碳、硫、粘土一起呈钼硫化物胶状集合体，经热接触变质作用后形成辉钼矿；铀呈不均匀分散在胶磷矿和碳泥质中，呈类质同象或吸附状态存在；稀土元素主要呈类质同存在于胶磷矿中，部分呈吸附状态存在；铜、铅、锌主要以硫化物和硫砷化物等存在，多富集在金属层中。

Aquatic or marsh-growing fern allies; known to have existed since the Cenozoic; sometimes included in Lycopodiales.

生活于水中或湿地的蕨类；从新生代生存至今；有时归于石松目之中。

The engine was uprated from a 90hp Franklin to a 125hp Lycoming.

改良过的引擎是从90hp到125hp莱康明富兰克林。
