Xiangshan volcano-intrusive complexes is the wall rock of the biggest volcanic-rock uranium ore deposit in China, and the main body is rhyolitic porphyroclastic lava, accompanied by hypahyssal or ultra-hypabyssal intrusive rocks such as dacite-porphyry and granite-porphyry Jiulongzhang volcano-intrusive complexes are dominantly rhyolitic welded tuff, accompanied by dacite-porphyry and quartz monzonite-porphyry, and so on, and the uranium resources are being assessed.

相山火山－侵入杂岩是华南地区最大的火山岩型铀矿赋矿围岩，其主体岩石为流纹质碎斑熔岩，浅成－超浅成侵入岩有英安斑岩、花岗斑岩等；九龙嶂火山－侵入杂岩的铀资源潜力尚待评价，主体岩石为流纹质熔结凝灰岩，浅成－超浅成侵入岩有英安斑岩、石英二长斑岩等。

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。

Nuclear fuel technology - Determination of uranium in solutions, uranium hexafluoride and solids - Part 2: Iron reduction/cerium oxidation titrimetric method

核燃料技术。溶液、六氟化铀和固体中铀的测定。第2部分：铁还原/铈氧化滴定法

The progress on the extraction of uranium from phosphate rock, lignite, carbonacious shale, uraniferous metallic complex ores and seawater is also described briefly. The progress on the disposal and treatment of effluent and tailings from uranium mill and technical flowsheet without producing wastes is also introduced concisely.

还描述了由磷炔岩、褐煤、碳质页岩、含铀多金属矿及海水提铀的重大新进展，扼要阐述铀水冶的废水及尾矿处理和铀水冶的无废物工艺流程研究的新进展。

That is, U-enriched muscovite peraluminous granites are the uranium source for metallogenesis, and the uranium is mainly devided from the parent granite rocks weathered and denudated, not from the hydrothermal solution derived from the parent granite rocks.

即铀含量较高的晚期二云母过铝质花岗岩是铀成矿作用的铀源，而且，铀源主要来源于被风化并剥蚀掉的那部分母岩，而不是来源于热液流体对现存母岩的交代。

In order to study the reaction kinetics of uranium with CO or CO 2,uranium samples of different forms are obturated in reaction vessels and then CO or CO 2 is filled in. Gases in vessels are analyzed at different storage time.

在一定温度下，将不同形态的铀样品密闭贮存在容器中并充入一定压力的高纯CO或CO2 气体，通过定期测量贮存容器中气体组成，初步研究了铀与CO或CO2 的反应动力学。

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。

Uranium weapons are armor-piercing munitions made of waste uranium-238, an extremely hard metal left in great quantities from the production of reactor fuel and nuclear weapons.

铀武器的穿甲弹药制造的废物铀-238 ，是一个非常硬的金属留在大批量从生产的反应堆燃料和核武器。

The Mo,U elements about normal geochemical method have a closely relationship with hidden uranium deposits. It has studied which methods is the most effective about this four methods through compare to drill material.After making compositive interpretation we can find this four method are effective on hidden uranium ore.We have the follow results: CR-39 track method and gama-ray spectrometer survey is better method than geochemical method.

最后通过这些单一方法实测测量结果与已知钻孔资料进行比较可以对该勘查方法的铀矿勘查效果进行评价；再从方法的单一研究到方法的综合研究，得出伽马能谱测量和固体径迹测量有效的结合，可以得到隐伏铀矿化的深部信息，而常规化探测量则可以有效划分近地表、深部铀矿化的区域。

It's not quite as simple as that.

并没有那么容易。

It debuted in 1992 in Japan and the United Kingdom, and 1993 in the United States.

它首次亮相于1992年在日本和英国，在美国1993年。
