The high rotten coal (including the anthracite and meager coal ) radioactive level is relatively low,( 238U: 29.1Bq/kg , 232Th: 25.9Bq/kg , 226Ra: 37.5Bq/kg), obviously lower than the radioactive levels of the brown coal and bituminous coal, and fluctuating range little relatively stable until Lincang uranium germanium colliery HeKai Tian little dragon's pool power plant make , investigate than right far correctly, prove natural radioactive nuclide (238U , 232Th , 226Ra ) than activity transformation in the course of utilizing and give locality radiate influence that environment bring.

高变质煤放射性水平相对较低，（238U：29.1Bq/kg、232Th：25.9Bq/kg、226Ra：37.5Bq/kg），明显低于褐煤和烟煤的放射性水平，且波动范围较小、相对稳定通过对临沧铀锗煤矿田和开远小龙潭电厂作出调查比对，说明了天然放射性核素（238U、232Th、226Ra）比活度在利用过程中的转移以及给当地放射环境带来的影响。

Thorium along with uranium (U belongs to the actinide group of chemical elements.

钍(16日)同铀(U所属的77锕系元素。

The comparison between thermal and fast ADS demonstrate that the fast ADS has large power output, less minor actinide production and small fission products poisoning effect compared with thermal system.

从快堆和热堆的比较可知，ADS的快堆具有输出功率大、长寿命超铀放射性废物的累积水平低、裂变产物对反应堆反应性和能量增益影响小等优点。

We started him on sodium bicarb to try to flush the uranium out of his system.

我们用了碳酸钠让他排出废铀

The Ordos Basin is a large-scale craton superimposed basin locating on the west of the North China platform, which is rich in oil, natural gas, coal, uranium and many other energy resources minerals. Many distinct subjects and points of view are needed in order to deeply study the characteristics of the occurrence and distribution of these energy resources in the basin.

鄂尔多斯盆地是位于华北地台西部的大型克拉通叠合盆地，含有丰富的油、气、煤、铀等多种能源矿产，研究这些能源矿产在盆地内时空的赋存分布特点，需要多个不同的学科，从不同的角度进行深入的研究。

In 1898, the Curies obtained a new element, whose radioactivity was several million times stronger than that of uranium.

1898年，居里夫妇获得了一种新元素，它的放射性比铀强几年居里夫妇获得了一种新元素，百万倍。

The extraction of uranium with petroleum sulfoxides in different diluents is studied.

研究了在不同稀释剂中石油亚砜对铀的萃取。

But if suspicions are correct that Iran has been secretly learning how to build and trigger a nuclear device, and shape a missile cone to carry such a warhead (as well as publicly developing nuclear-capable, far-flying missiles), then once it has fully mastered uranium enrichment it will soon be poised to break out at short notice, at a moment of its choosing.

但如果怀疑是正确的，即伊朗一直在秘密研究如何制造和引爆一个核装置，并设计能携带这类弹头的导弹（以及公开研发能运载核弹头的远程导弹），那么，一旦伊朗完全掌握铀浓缩技术，它就可以很快做好在其选定的时机立刻启用核武器的准备。

Iran's tests of increasingly far-flying rockets, and its repeated refusal to heed UN Security Council deadlines to end nuclear work that could be abused for bomb-making, have convinced even NATO's sceptics that limited defences can bolster security in Europe too.

伊朗正在试验射程更远的导弹，而且再三对联合国安理会做出的相关最后期限视而不见，而这些期限旨在勒令伊朗停止可能用于核弹制造的铀浓缩活动。这甚至使得北约的批评者相信有限的反导防御能够捍卫欧洲安全。

They especially want answers about studies that appear to show as yet undisclosed uranium-related work, high-explosive testing of triggers for nuclear bombs, a plan for an underground nuclear-test shaft and efforts to redesign the nose-cone of Iran's far-flying Shahab-3 rocket to accommodate a nuclear warhead.

IAEA也特别关注下面一些问题的答案：秘密进行的铀关联工程；击发核弹的高爆试验；地爆竖井计划；伊朗是否对&流星3&型远程地对地导弹头锥改进，使之具有配载核弹头的能力。
