摘　　要：通过分析石膏脱水过程，研究石膏的脱水动力学机理，指出石膏的脱水过程包括：受热分解和反应产物水蒸气的扩散．同时测定了３种脱水相的物理力学性能，并给出石膏脱水动力学方程．By analysing gypsum dehydration process and studing the equation of gypsum dehydration kinetics,the paper points out that the dehydration Process of gypsum includes thermal decomposition and diffuse process of reaction products.The physical mechanical properties of three dehydrated phases are measured that provides a theoretical basis for producing building gypsum.
