Uranium and Impurity in U3O8 八氧化三铀中铀和杂质元素成分分析标准物质
After exposure to carbon monoxide, contents of oxygen in the surface oxides of uranium metal and U3O8 are decreased and O/U ratios decrease 7. 2% , 8.0% respectively.
在一氧化碳气氛中金属铀表层氧化物和八氧化三铀中氧含量减少，O/U比值分别下降了7.2％和8.0％。
The use of U3O8 additive can improve the pellet microstructure, but result in decrease of pellet density and increase of open porosity, which contributes strongly to moisture.
采用U_3O_8添加剂可改善芯块微观结构，但同时使芯块密度下降，开口孔隙度增加进而导致吸湿加剧。
The surface structures of uranium metal and triuranium octaoxide (U3O8) and the influence of carbon monoxide to the surface layers have been studied by X-ray photoelectron spectroscopy (XPS).
用X射线光电子能谱（XPS）分析研究了金属铀表层和八氧化三铀的表面结构以及一氧化碳对其表面结构的影响。
