By partial and general dissection of large prebaked alumina electrolysis cells, the macro appearance, chemical composition and phase variations were studied emp
The optimal condition and its geometrical characters of the least-square adjustment were proposed. Then the relation between the transformed surface and least-s
Both porosity (φ) and permeability (k) of the weathered elution-deposited rare earth ores are basic hydrodynamic parameters for RE leaching. The relationship b
The synthesis process for La1-x Srx Mn1-yCoyO3-δ ( x = 0.2, 0.3; y = 0.2, 0.8, designated as LSMC below) perovskite oxides prepared by solid state reaction was
