Important natural geological analogues are volcanic glass and meteoric glass(anal-ogues of solidified mass), clay minerals (natural analogues of backfill material), iron meteorite and copper deposits (natural analogues of waste containers), natural nuclear reactors, uranium deposits, iron deposits containing Th and REE and contact zones between igneous rocks and other rocks (natural geochemical analogues of HLW repository).

目前已有的地质类比研究对象主要有火山玻璃，陨石玻璃，粘土矿物，铁陨石，铜矿床，铀矿床，含含Th和REE的铁矿床，天然核反应堆和火成岩接触带等。

The GEOTOP centre develops multi-disciplinary projects such as the study of uranium-thorium-radon desequilibrium in volcanology or the study of isotopic tracers at the water-sediment interface and internal process of the earth.

此中心开展了多学科的研究项目，如火山学中铀-钍-氡消除平衡的作用研究、水沉积物分界面的同位素示踪剂研究，以及地球内部作用的研究。

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 one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
