摘　　要：对多孔介质快速干燥过程的传热与传质耦合方程组导出了两套代数显式解析特解。这些解首先可以作为计算传热传质学的标准解,用以检验数值计算的准确性、收敛性与稳定性等,还可以启发数值工作者改进计算技巧例如差分格式与网格生成技术等。当然,解析解还会有其相应的理论价值。Two algebraically explicit analytical solutions of the governing equation set for the coupled heat and mass transfer process of rapid drying in porous media are derived. These solutions can be the benchmark solutions of computational heat and mass transfer to cheek the accuracy, convergence and effectiveness of various numerical methods and to improve some computational skills such as the difference schemes, grid generation ways and so on. Of course, the analytical solutions have their own theoretical value as well.
