Structure and magnetic properties of intermetallic compounds Gd5Si2-xGe2-xM2x LUO Guang-sheng(罗广圣)1, 2, LEI Yu(雷 宇)2, 3, XIN Yong(辛 勇)4, ZHOU Zheng-you(周正有)2 1. School of Materials Science...: The effects of substituting stable elements of M(M=Mn, Mo, Al, V) for nonmagnetic Si and Ge on the structure and magnetic properties of Gd5Si2Ge2 were investigated by means of X-ray powder diffraction......
; 文献标志码:A 文章编号:1672-7207(2012)05-1808-06 A lexicalized syntactic parsing model based on valence structure YUAN Li-chi (Jiangxi Key Laboratory... valence structure with head-driven statistical syntactic parsing models was purposed, which incorporates rich semantic information including semantic dependency and semantic collocation. Experiments......
investigated. The results show that the structure of the material is a mixed phase of α-Ni(OH)2 and b-Ni(OH)2, which has a the same stabilized structure as α-Ni(OH)2 during long-term charge/discharge process... higher reduction potential. They exchange one electron during electrochemical reaction and have a higher proton diffusion coefficient. The mechanism of the electrode reaction is proton diffusion......
Second-order nonlinear optical properties of Ge-Ga-Ag-S glass irradiated by electron beam TAO Hai-zheng(陶海征), DONG Guo-ping(董国平), XIAO Hai-yan(肖海燕), LIN Chang-gui(林常规), ZHAO Xiu-jian(赵修建) Key... chalcogenide glass after irradiated by an electron beam (Accelerating voltage: 25 kV; Irradiating current: 15 nA; Irradiating time: 10 min). And the mechanism of second-harmonic generation in the Ge-Ga-Ag-S......
2010 Abstract: The phase structure of ZK60-1Er magnesium alloy thermally compressed at the temperature of 450 ?C and the strain rate of 1×10-4 s-1 was determined by transmission electron microscopy (TEM) and high-resolution electron microscopy (HREM). The results show that this magnesium alloy contains many new W phases (Mg3Zn3Er2, FCC structure) in the matrix. Those new W phases have two......
bonding peaks of both Mg3Pd structure are in the energy range between about -3.4 and -2.6 eV under Fermi level, which are mainly dominated by the valence electron numbers of Pd(d) and Mg(p) orbits... region of Fermi level are the mainly bonding electron, when more electrons are in low-energy region, the bonding electron increases, and the interaction between valence electrons of crystal is intensified......
Structure and mechanical properties of aluminum alloy/Ag interlayer/steel non-centered electron beam welded joints ZHANG Bing-gang1, CHEN Guo-qing1, ZHANG Chun-guang1, NI Jia-qiang2 1. State Key... 2011 Abstract: Electron beam welding was carried out between aluminum alloy and steel with Ag interlayer. Seam morphology, structure and mechanical properties of the joints were investigated......
Effect of Different Doses of Electron Beam Irradiation on the Structure of PAN Precursor Fibers and Resultant Stabilized Fibers余红伟1,WANG Yuansheng1,3,WEI Zheng1,夏革清41. Department of Chemistry.... The effect of electron beam irradiation on the chemical structure, crystallite size of PAN precursor fibers and density, oxygen content, transverse section morphology of the stabilized fibers......
