Results show that deuterium absorption quantity and velocity decrease with helium content increase. Absorption velocity increases with initial pressure, and keeps constant at different initial composition of uranium deuteride.
结果表明,氦含量的增加会显著减少铀的吸氘量,降低铀的吸氘速率;增加混合气体的初始压力有利于铀吸氘速率的增加,氘化铀的初始氘量不影响铀的吸氘速率。

Uranium solution is obtained electrolytically by reducing uranyl ion on mercury cathode. The effect of the addition of various aminopolycarboxylic acids (such as EDTA, DTPA, CyDTA and TTHA) and organic water-miscible solvents (such as CH3OH, C2H5OH and CH3COCH3) on the stability of ura-nium in air has been investigated. The absorption spectra of uraniumand uraniumin 1 mol/l and 9mol/l hydrochloric acid solutions are examined.

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。

By above research, the following results are obtained.(1)The extracting module of aero-radioactive thematic information is integrated with ENVI, the remote sensing image processing software;(2) Based on the IDL, the computer program modules extracting following uranium thematic information have been developed, including initial uranium contents, active uranium contents, uranium migration coefficient, uranium information strengthen, uranium D-value and variance Ratio etc, al. Some of kalium special information extracting modules are also developed;(3)Based on the IDL, the aero-radioactivity information multi-parameter focus analysis module is developed;(4) It is proposed that a lots of phenomenon of uranium immigrating exist in Keping-Kuche are in the Neocene period. Because of the uranium pre-enrichment, the areas with high uranium content were formed in Neozoic and Quaternary. The above migration uranium are also the abundant source for uranium ore-forming in favorable strata of Mesozoic and Cenozoic system;(5)There are obvious uranium immigrating and enrichment in Eastern Portion of Keping Block Uplift, Yinate-Laolongjiang, and Qidaoban-KuChe.
通过上述研究,取得了如下成果:(1)实现了航放专题信息提取模块与ENVI遥感图像处理软件的无缝集成;(2)基于IDL语言开发了初始铀含量、活性铀含量、铀迁移系数、铀信息增强、铀差值方差比等航放铀专题信息,钾专题信息提取处理程序;(3)基于IDL语言开发了航放信息多参数聚焦分析处理程序;(4)发现柯坪-库车地区在晚第三纪开始出现了大量的铀迁移富集现象,不仅使上第三系、第四系沉积时因铀的预富集而形成铀含量高场区,而且也为研究区中新生代有利目的层的铀成矿提供了铀源条件;(5)研究认为,研究区柯坪断隆东段,英阿特-老龙江,七道班-库车等三个区块存在明显的铀迁入富集。
