铀

The uranium may be present in only very low concentrations - a few parts per million - in the form of the uranyl iron, UO 2 (the same ion present in the mineral Zippeite), but it can be recognized by the distinctive fluorescence.

铀，可目前只在非常低的浓度-数百万分之-在形式上的铀铁， u o 2（同一离子目前在矿产zi ppeite），但它可以通过独特的荧光。

Three heteronuclear uranyl complexes were obtained via hydrothermal reaction, too.

另外，在水热条件下，还利用这些芳香有机酸合成了三个铀的异核金属配位聚合物，这为铀的异核金属配合物家族增添了新的成员。

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）。

There are several premier uranium districts, which have a history of large-scale uranium production: Athabasca, Australia's Northern Territories or South Australia, Grant's New Mexico, Wyoming, Kazakhstan, Niger, and Namibia.

有几个总理铀区，其中有历史的大型铀生产：的Athabasca，澳大利亚北部地区或南澳大利亚，Grant的新墨西哥州，怀俄明，哈萨克斯坦，尼日尔和纳米比亚。

In alkali metasomatic rocks, potassium is in reverse correlation with gold; and sodium is in reverse correlation with uranium, it is very important to ore-formation of uranium and gold.

研究中还认识到，在碱交代作用形成的碱交代岩中，钾与金负相关，钠与铀负相关，这对铀、金成矿有着重要的意义。

Thus, SRB were likely to reduce sulfates to sulfides simultaneously with petroleum oxidization, and directly or indirectly reduce hexavalent uranium U to tetravalent uranium U to precipitate pitchblende.

于是，利用烃类作为生存的碳源，硫酸盐还原菌将硫酸盐还原的同时，直接或间接地把六价铀U还原成四价铀U，导致沥青铀矿形成。
