类号:Q 939 文献标识码:A Bioleaching of chalcopyrite concentrate using mixed thermophilic culture and succession of microbial community during leaching process Liu Kai1, Diao... pH 2.5. The copper extraction at 75 ℃ is lower than that at 65 ℃, but the lower copper extraction at 75 ℃ is not due to the inhibition of the high temperature. The succession of the microbial......

Large magnetic-field-induced strains in rare earth polycrystalline Ni-Mn-GaZHAO Zengqi, WU Shuangxia, WANG Fangshu, WANG Qiang, JIANG Liping, and WANG Xinlin 1) Baotou Research Institute of Rare...-field-induced strains (MFIS) of polycrystalline Ni50Mn29Ga21 alloys containing Tb were studied. A large MFIS of-1.10% was obtained under compressive prestress conditions. The addition of Tb can fine......
Residual strains of aluminum alloy characterized by nanoindentation WANG Yan-shen(王延深)1, 2, QU Shi-liang(曲士良)3, GAI Yu-xian(盖玉先)2, DONG Shen(董 申)4, LIANG Ying-chun(梁迎春)4 1. Department of Physics...: A formula was brought forward to correlate residual strain with hardness measured by nanoindentation method. Using the formula, residual strains in prestrained aluminum alloy samples were evaluated......
Molecular characterization of Acidithiobacillus ferrooxidans strains isolated from different environments by three PCR-based methodsWU Xue-ling(吴学玲)1, 2, LIU Li-li(刘莉莉)1, 2, ZHANG Zhen-zhen(张真真)1, 2... analyses were used to characterize 23 Acidithiobacillus ferrooxidans strains isolated from different environments. (GTG)5 and BOXA1R primer were selected for REP-PCR. Twenty arbitrary primers were used......
