摘　　要：介绍格子气自动机方法的原理与特点.用该方法模拟非饱和多孔介质微观干燥过程,实现多孔介质干燥时内部湿分分布状态、迁移特征的可视化;分析影响干燥过程的主要因素,模拟结果与理论分析结果符合.初步研究表明,该方法能够有效地模拟多孔介质干燥过程,实现对多孔介质微观干燥过程进行可视化分析.The characteristics and theory of lattice gas automata have been introduced. Drying process of water in unsaturated porous media was simulated by this method. A series of moisture distribution and transfer images were obtained by computer simulation. The affect of the main factor on drying process was analyzed. The researches show that the results of simulation accord with the results of analysis in theory. The method is valid to offer visualization means for microscopic drying process in porous media.
