FEA modeling of effect of axial feeding velocity on strain field of rotary swaging process of pure magnesium RONG Li(荣 莉), NIE Zuo-ren(聂祚仁), ZUO Tie-yong(左铁镛) School of Material Science... for d=7.0mm. The increase of vax has no notable influence on strain distribution along radial direction. The errors between the experimental and simulated height of the spiral spine-like ridges......
leaching rate of metal sulfides[6-7]. With view of the above discussion, a study was undertaken to identify a newly isolated heterotrophic acidothermophilic strain YNTC-1 coexisting in an acidic hot... that the heterotrophic strain YNTC-1 has no effective influence on the bioleaching rate of chalcopyrite by strain YN22. From the leaching curve, it is obvious that the dissolution rate of iron (from slope of the curves......
