铀

S ., last year consumed some 12,700 short tons of processed natural uranium ore （ in the form of the oxide known as yellow cake , or U 3 O 8）. It is estimated that by 1985, When nuclear power is scheduled to account for perhaps a fourth of the total U .

据估算，到1985年，核电预定达到美国总装机容量的1/4时，新鲜核燃料的消耗率会达到至少每年55，000美吨黄饼（假如有些使用过的核电料还能以再处理过的铀和钚的形式重新使用的话）；最多每年62，000美吨黄饼。

In the Purex process, the separation of plutonium from uranium is achieved by using reductants which can quickly and quantitatively reduce Pu to Pu.Up to now the reductant U-N2H4 is still used widely for separation of Pu from U in the rep...

目前动力堆乏燃料后处理中广泛采用的钚还原剂还是由肼支持的四价铀，而醛、肼、羟胺类有机无盐还原剂在Purex流程中的应用目前还停留在实验室研究阶段。

Based on the above studies and integrated with aerial radioactivity data, the authors identified and mapped such spectral features of main ore-forming factors of uranium deposits as ore-controlling faults, hydrothermal alterations and plutons, and evaluated geological application potentials of CBERS-02B remote sensing imagery in the Taoshan granite-type uranium deposit.

在此基础上，以江西桃山花岗岩型铀矿田为试验区，结合航空放射性数据，开展了基于02B星遥感数据的控矿断裂带、热液蚀变带及主要成矿岩体等铀成矿要素的光谱特征识别与提取，并对该数据的地学应用潜力进行了评价。

Exceptionally strong long-term demand continues to exert upward pressure on the spot uranium price as each pound held by sellers is considered more valuable with every new buyer that enters the market.

异常强劲的长期需求，不断施加压力的铀现货价格为每磅所持卖家被认为是较有价值的，与每一个新的买主进入市场。

美国认为，对伊朗的能源出口进行制裁或可迫使德黑兰放弃其铀浓缩的野心；伊朗则希望以威胁停止部分或全部石油出口来迫使国际社会作出让步。

As a result of a However, as a result of nuclear reactions (which might be caused by the bombardment of atoms by protons, neutrons or other light particles), nuclei can be produced in an excited or unstable condition in which one or a number of nucleons are raised to an excited state.

运 行过程中，二氧化铀芯块需要承受结构变化，主要是由于高的运行温度和高温度梯度造成的，同时也是长期受到辐照的结果。

The rabbit osteoarthritis model were duplicated by Hulth's technique. The pathologyical changes of each group was observed with naked eyes before taking the thighbone department carilage of pulley block and the platform place of shine bone carilage, then under the light microcope and the transmission electron microcope respectively, after treating with Semer Strychni (high、middle and low dose) for two months.

按Hulth法造兔膝骨关节炎模型，用马钱子高、中、低剂量进行灌胃治疗，连续2月后取材，进行肉眼大体观察后，取股骨滑车部软骨及胫骨平台处软骨，分别于HE染色后光镜下观察和铀-铅双重染色透射电镜下观察各组的病理变化。

There are gold, silver, iron, manganese, molybdenum, uranium, mica, vermiculite, quartz rock, feldspar, granite, marble, barite and mineral water, and so on.

主要有金、银、铁、锰、钼、铀、云母、蛭石、石英石、钾长石、花岗岩、大理石、重晶石和矿泉水等。
