of alumina particles. An alumina particle is used to represent a certain number of actual alumina particles. When calculating the alumina concentration, the actual dissolved mass is that a single particle... on the alumina concentration and the superheat of the electrolyte, and particles with good dispersion can be dissolved quickly. With the increase of mass, the difference of alumina concentration......
concentration ratio was presented, which was directed towards the deformation performance, that is, the discrete material pile not only had a vertical deformation but also had a lateral deformation under... of both discrete material pile and surrounding soil were analyzed. Based on the elastic theory and Terzzaghi’s one dimension consolidation theory, a modificatory method for stress concentration ratio......

Effect of Polyvinylidene Fluoride Hollow Fiber Membranes on Mass Transfer of Samarium LI De-qian1,ZHANG Feng-jun1,LUO Fang1,WU Yong-lie1 (1.Laboratory of Rare Earth Chemistry and Physics, Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022,China) Abstract:The influence of swelling and stripping acidity on the mass transfer coefficient based on water phase......
by the increased activation, which leads to spontaneous combustion under appropriate conditions ultimately. Key words: sulfide ores; mechanical action; oxidation mass gain; spontaneous combustion..., and the oxidation mass gain rates of the activated samples were compared. The results show that small particles and agglomeration effects are formed after sulfide ores undergo mechanical activation......
