One scientist noticed a mark on a photographic plate that was near uranium.

当时，有一个科学家注意到，在一个靠近放置铀元素地方的照相底板上多出了一个记号，他不知道这个记号是怎样会产生的。

And therefore we kept a very close eye, as governments do in their various ways, on Iraq trying to get hold of nuclear base materials, such as uranium or uranium yellowcake, or trying to get the machinery that was necessary to develop nuclear-weapons-grade material.

所以我们总是密切注意，政府会用各种不同的渠道，留意伊拉克试图得到核物料，如铀或者黄铀矿，或者试图获得加工核武器级别核原料的机器。

Exports to Iran of purified uranium known as "yellowcake" would breach United Nations sanctions imposed on Tehran for refusing to freeze its uranium enrichment programme.

向伊朗出口有&黄饼&之称的提纯铀，将违反联合国因伊朗拒绝冻结铀浓缩计划而实施的制裁规定。

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。

Uranium deposit No.337 in Xiazhuang uranium orefield has been regarden as a representative of the earliest forming, relatively high temperature and short time gap between the formation of pluton and the mineralization.

长期以来人们一直认为337铀矿床是下庄铀矿田成矿年龄最早、成矿温度相对较高、矿岩时差小的岩浆热液型铀矿床的代表。

The meso-epithermal uranium deposit described in this paper is closely related to the"multiple-staged"composite quartz-syenite body, It is a new of uranium type deposit in our country.

本文介绍的中-低温热液轴矿庆与一个多阶段复式石英正长岩体密切有关。它是我国新的一种轴矿床类型。

Uranium mineralization occurs when interlayer water with oxygen and uranium enclosed in primary red beds meet with reduction fluids along fractures.

矿化成因为原生红层中封存的含氧含铀层间水同沿断裂进入的还原溶液互相作用的结果。

Results showed that the amount of tritium residual in the glass uranium was 2.68%, namely there was (0.0308±0.0003) mmol tritium per gram uranium. The standard deviation of PVT measurement method based on the state equation of the ideal gas was less than 0.95%, when the pressure was between 1500 and 133332 Pa.

直接测量法测量铀床的氚残留量的结果如下：铀床的氚残留量为2.68%，即每克铀含(0.0308±0.0003) mmol 氚气；当压力读数在1500～133332 Pa之间时，基于理想气体状态方程的测量方法的标准差小于0.95%。

The uranium is then dissolved from the beads using a solution of ammonium carbonate and precipitated as "yellow cake", a mixture of uranium oxides.

接下来，小珠子里头的铀离子会被碳酸铵溶液溶解，其后沉淀，析出&黄饼&，即各种铀氧化物的混合物。

This is a marksmanship nuclear cruise missiles, its nuclear fuel loading is from natural uranium -235 electromagnetic separation of uranium-rich set production.

这是一颗枪法核航弹，其核装料铀－235是从天然铀用电磁分离法富集生产的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
