摘　　要：通过明确岩盐的溶解特性实验和NaCl溶液扩散的实验研究,本文探讨了岩盐溶解过程中其构成成分的NaCl从岩盐体的溶解分离过程和NaCl溶液的传质过程,得出了岩盐溶解速率、扩散系数受各项因素影响的变化规律以及其相应的计算公式,建立了岩盐溶液的动态平衡微分方程,供同行借鉴。Through experiments to clarify the dissolution characteristics of rock salt and experimental studies on the diffusion of NaCl solution,this paper discusses the dissolution and separation process of NaCl components from rock salt bodies and the mass transfer process of NaCl solution during the dissolution process of rock salt,and obtains the change law of rock salt dissolution rate and diffusion coefficient affected by various factors and corresponding calculation formulas.The dynamic equilibrium differential equation of rock salt solution is established for reference.
