of ores and bacterial strains. Under such leaching conditions as the initial pH value of 1.5, temperature of 50℃, pulp density of 5%, particle size less than 35.5μm (over 90%) and inoculating the adapted strains of MLY, the leached Zn is over 95% after 10d of bioleaching. SEM observations show the cell attachment and the surface features of solid residues under different leaching conditions. XRD......
="ChDivSummary">For a better understanding of the strains and stresses,numerical simulation was conducted by using ANSYS under the assumption of absolute bond between the steel and concrete.The results show that the stresses and strains in such concrete and steel rings are uneven;the curves of strains and stresses change gradually around the interface.To ease numerical computation,the mechanical......
