J. Cent. South Univ. (2016) 23: 729-739 DOI: 10.1007/s11771-016-3118-9 Applications of fluid substitution effect analysis on seismic interpretation CHEN Wei(陈伟)1, 2, WANG Shang-xu(王尚旭)1, 2, CHUAI... production and recovery. By a time-lapse seismic method, we study the effects of fluid substitution in a physical model, which is an analogy of the three-dimensional inhomogeneous reservoir. For a weak......
Effects of sodium substitution on properties of LiMn2O4 cathode for lithium ion batteries GUO Hua-jun(郭华军)1, LI Xiang-qun(李向群)2, HE Fang-yong(何方勇)1, LI Xin-hai(李新海)1, WANG Zhi-xing(王志兴... with molar ratios (x= n(Na)/n(Mn)) of 0, 0.01, 0.02 and 0.03, respectively, and then Na-doped spinels were synthesized using a sol-gel process. The effects of the sodium substitution on the structure......

Effect of erbium substitution on thermoelectric properties of complex oxide Ca3Co2O6 at high temperatures PEI Jian1,CHEN Gang1,LU Dongqing1,XIAN Hengze1,YANG Xi1 (1.Department of Applied Chemistry... Temperature Sintering procedure (LTS) to evaluate the effect of Er substitution on the thermoelectric properties of Ca3Co2O6. The crystal structure and microstructure were investigated using X-ray......
Effect of B and Fe substitution on structure of AB3-type Co-free hydrogen storage alloy WU Feng(吴 锋)1, 2, ZHANG Min-yu(张旻昱)1, MU Dao-bin(穆道斌)1, 2 1. Beijing Key Laboratory..., within which Ni of La0.7Mg0.3Ni3 alloy was substituted by Fe, B and (FeB) alloy, respectively. Alloys were characterized by XRD, EDS and SEM to investigate the effects of B and Fe substitution for Ni......

China 25(2015) 520-526 Effect of Sn substitution for Co on microstructure and electrochemical performance of AB5 type La0.7Mg0.3Al0.3Mn0.4Co0.5-xSnxNi3.8 (x=0-0.5) alloys... March 2014 Abstract: The effects of substitution of Sn for Co on the microstructure, hydrogen storage and electrochemical discharge capacity of La0.7Mg0.3Al0.3Mn0.4Co0.5-xSnxNi3.8 (x=0, 0.1, 0.2, 0.3......
化峰和还原峰,且峰电位差较小,反映合金电极较好的吸放氢反应可逆性. 关键词:La-Mg-Ni-Al;La-Mg-Ni-Co-Al;贮氢合金;Al替代 中图分类号:TG139.7 文献标识码:A Effect of Al substitution on electrochemical performance of La-Mg-Ni... the effect of Al substitution on electrode characteristics. The results show that all alloys are composed of LaNi5,La2Ni7 and LaNi3 phases. With the increase of x value, the cell volume of La2Ni7 phase......
on microstructure and electrochemical properties of LaNi4.2-xCo0.6MnxAl0.2 alloys were investigated systematically. The results of XRD analyses indicate that the substitution of Mn does not change the crystal structure, but along with the increase of Mn substitution quantity, the volume of the crystal increases and the ratio of axial to radial lattice parameters (a/c) first increases, then decreases......
Se AND Bi SUBSTITUTION EFFECT IN Sb2Te3张建摘 要:<正>The Discrete Variational Xa Method DVXa with an embeded cluster scheme was used to investigate electronic structure, energy levels, charge distribution and chemical bonding in p-type thermoelectric ceramics:Sb2Te3-Bi2Te3-Sb2Se3. The results obtained are in agreement with experiment ones, which......
