摘要
基于含湿多孔介质的水分蒸发过程及其内部毛细管水分的蒸发特性和毛细孔隙的分布规律,讨论了含湿多孔介质中孔径分布对水分蒸发过程的影响,加深了对含湿多孔介质水分蒸发过程的物理机制的认识:在多孔介质的降速干燥阶段,蒸发过程只在介质内部的某一蒸发区间内进行。
Based on the characteristic of the moisture evaporation inside a porous material and tile pore distribution, the physical mechanism of moisture evaporation inside porous material during drying process was analyzed：moisture evaporation conducted only in someone moisture evaporation region during the de.creasing rate period of drying.
