thermal expansion coefficients agree well with the experimental data as well; and when FCC-Cu is transformed into Liquid-Cu, the free and covalent electrons are transferred into nonbonding electrons..., the increase of the single bond radius and the atomic volumes of Liquid-Cu. Key words: FCC-Cu;Liquid-Cu;electronic structure;Debye-Grüneisen model; CALPHAD method  ......
surface roughness is less than 10 nm and sp3-bonded content is greater than 70% can be prepared by bistratal filament structure with optimized proportion of Ar. It is also shown that the friction...); nano-mechanics properties; bistratal filament structure......

Structure and production fluid flow pattern of post-fracturing high-rank coal reservoir in Southern Qinshui BasinLIU Shi-qi(刘世奇)1, SANG Shu-xun(桑树勋)2, ZHU Qi-peng(朱启朋)2, LIU Hui-hu(刘会虎)3, GAO He... and average method. Based on the structure model and flow pattern of post-fracturing high-rank coal reservoir, flow patterns of methane and water were established. Results show that seepage pattern of methane......
Phase structure and hydrogen storage properties of REMg8.35Ni2.18Al0.21 (RE=La, Ce, Pr, and Nd) hydrogen storage alloys刘岩青1,韩树民1,2,扈琳1,刘宝忠2,3,赵鑫1,贾彦虹11. College of Environmental and Chemical... and REH x (x=2.51 or 3) phases in hydriding. CeH2.51 phase transformed into CeH2.29 phase in dehydriding, whereas LaH3 , PrH3 and NdH3 phases remained unchanged. The PrMg8.41Ni2.14Al0.20 alloy had......
