单级实验结果表明，正丁醛的加入和延长正丁醛与镎的相互作用时间，有利于从有机相中反萃镎；正丁醛的加入对铀、钚分配比的影响不大；但铀浓度增加会增加镎的反萃。

Pitchblende and chalcolite are much more radioactive than uranium itself.

沥清铀矿和铜铀云母比纯铀的放射性强得多。

Chalcolite ( crystallized phosphate of copper and uranium) is about twice as radioactive as uranium.

铜铀云母的放射性是铀放射性的两倍。

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%。

Examing neutron integral flux is an important part of fission track technique, and determining neutron integral flux by using uranium standard glass is recommended as a mainmethod by international Fission Track Standardization Group for age-dating.

监测中子积分通量是裂变径迹技术的重要组成部分。铀玻璃监测中子积分通量是国际裂变径迹定年标准化工作组推荐的重要方法之一，铀玻璃测定法还普遍用于测定样品中的铀含量及其空间分布。

In order to separate trace plutonium from uranium matrix for subsequent mass spectroscope determination of the former,an extraction chromatographic method composed of a TBP extraction resin column and a cationic exchange resin column was developed.

为了从铀基体中分离痕量钚，采用由TBP色层柱和7402季铵盐色层柱组成的萃取色层法及低本底α谱仪对模拟铀样品中铀钚分离方法进行了研究，并确定了分离流程的条件；对影响流程分离效果的主要因素，如料液和洗涤液酸度、流速、解吸液浓度等进行了研究，确定了最佳分离流程。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
