Methods Uranium oxide particles were classified with a cascade impector.

目的研究现场采集的不同粒径铀氧化物在人体模拟肺液和相关的缓冲体系中的溶解特性。

The prime minister John Howard says Australia could quadruple its 2005 revenue from exporting uranium oxide (mainly to America, France and Japan) if it enriched and fabricated the fuel first.

约翰·霍华德总理说，澳大利亚如果能提纯并制造燃料级的氧化铀再出口的话（主要出口美国，法国和日本），它从中得到的财政收入将可能是2005年的4倍。

The optimum condition of spectrofluorimetric determination of uranyl ion in pyridine 2,6 dicarboxylic acid β cydodextrin system is studied.

研究了吡啶 2 ，6 二羧酸β环状糊精体系荧光分光光度法测定铀酰离子的最佳条件以及某些稀土共存离子对荧光体系的干扰，并应用于人工样品的测定。

It was found that the selective photoreductionreaction of this uranyl compound could take place under pulsed IR laser irradiation and the rate ofphotoreduction depended on the frequency, energy fluence and numbers of pulses of laser.

用TEA-CO_2激光研究了室温下固体的甲酸铀酰钠的红外光化学反应，发现该化合物在脉冲红外激光照射下可产生选择性的光化还原反应，其光化还原率与激光频率、能量密度和脉冲数有关。

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。

There is, indeed, an admitted linguistic difficulty in the change of the sound i into u, but may it not have been that this was accomplished, not grammatically, but by popular witticism?

的确，语言上的承认，难以改变的声音字母i到铀（ Tsaddiqim到Tsadduqim ），但它可能没有，这是完成的，而不是语法，而是由流行妙语？

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。

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。

Item No.: HCG-U-001The USB band is Driverless (except Win98), no external power supply.

闪光的USB驾驶硅手链项目编号：⊙-铀001的USB波段是无人驾驶(除WIN98的)，任何外部电源。

Results In the medium and high dose F0 groups, it was observed that the atrophy and incrassation of seminiferous tubule, decrease of spermatogenesis, hyperplasia of interstitial tissue, especially in high dose groups spermatozoon abnormality and nucleolus concentration in the rats testis after DU ingestion for 14 months.

结论长期摄入贫铀对大鼠组织脏器的损伤具有一定的时间性和组织特异性，主要损伤集中在雄性生殖系统、免疫系统和造血系统，而对其他组织的损伤不明显。

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。
