摘要：
The damping configuration curves of vaporizing rate Es vs time t for moist porous mediums are found in this paper. It shows the exponent shape for integrated porous material and "S" shape for loose medium. Loose medium is much more sensitive to moisture migration than integrated. A dynamic moisture sedimentary interface is also found existing in the medium, it is influenced by periodic thermal impact on the top and bottom surface of the medium, and it moves periodically as follow course: generation-immersion-floatation-dissipation.
