The heat and mass transfer process and the parameters of heat and moisture transfer in the porous media were analyzed. One-dimensional equations of heat and moisture transfer process were established. The temperature and humidity distributions in the porous media were solved by the characteristic function method. Least square fitting to obtain the parameters of the thermal and moisture characteristics of the porous material containing moisture
