研究了等温条件下盐在完全饱和砖中的扩散。采用一种常用的实验方法——扩散池法来估算盐的扩散系数。建立了数学模型。给出了近似解析解。解与数值解一致。扩散池法的解析解在许多领域有着广泛的应用。此外，还讨论了不同类型的盐对不同类型砖的扩散系数。
The salt diffusion in fully saturated brick at isothermal condition is investigated. A commonly used experiment methodology, diffusion cell method, is adopted to estimate the salt diffusion coefficient. The mathematical model is developed. An approximate analytical solution is given. The solution agrees with the numerical solution. The analytical solution has applications in a wide number of fields with diffusion cell method. Furthermore, the diffusion coefficients of different types of salt for different types of brick are discussed.
