Together, a BHP-Rio would produce more than 25 percent of the world's uranium oxide supply.

如果必和必拓集团和力拓集团合并，将控制全球25%的氧化铀供应。

The relationship between burnup and neutron emission intensity of the irradiated low-enrichment uranium oxide fuel was analyzed and studied.

对辐照过的低富集氧化铀燃料的燃耗与中子发射强度间的关系进行分析和研究。

Uranium oxide was soluble in Na2CO3 solution and basically insoluble in NaH2PO4-Na2HPO4 solution.

铀氧化物在Na2CO3溶液中易溶，在NaH2PO4-Na2HPO4体系中几乎不溶。

The enriched uranium is sent to other plants, where it is transformed into uranium oxide in the form of small pellets.

富集了的铀被送到其他工厂转化成小球状的铀氧化物。

At the same time, the international market price of uranium soared in recent years all the way from eight in 2000 before a pound of uranium oxide rose to 10 U.S.

同时，国际市场铀价格近年来一路飙升，已从2000年前每磅八氧化三铀10美元上扬至去年7月每磅138美元，现在虽降到每磅44美元，但对跨国大型采矿企业来说仍有可观的利润空间，据测算铀的成本在每磅40美元左右。

It resumed its work at the plant near Isfahan, where uranium oxide is converted to uranium hexafluoride gas--but only under the watchful eyes of the IAEA inspectors.

它重新开始它的工作在植物近的 Isfahan，哪里铀氧化物是转换对铀 hexafluoride 瓦斯--除了只有在那之下注意的眼睛国际原子能总署检查员。

The oxidation kinetics of depleted uranium was studied in pure oxygen pressure of 5 kPa at below 100°C by using spectroscopic ellipsometry. The relationship of the thickness of uranium oxide with time is measured. The results indicate that below 100°C in the initial period, the relationship between oxidation layer thickness and time is parabolic. The oxidation mechanism of depleted uranium is discussed and the active energy of depleted uranium at given experimental conditions is 87.165kJ/mol from calculation.

采用椭偏技术研究了45~95℃和5kPa纯氧气氛中金属铀的氧化，通过不同温度下金属铀表面氧化层厚度随时间的变化规律，得到贫铀在初始氧化阶段的表面氧化层厚度与时间的关系均呈现抛物线规律；绘制出了在不同温度下金属铀表面的氧化动力学曲线，由此得到在低于100℃，5kPa的纯氧气氛下贫铀表面形成氧化物的反应活化能为87.165kJ/mol。
