摘　　要：用Matlab求解伴有凝结发生时多孔织物的动态热湿传递数学模型,指出Matlab在运用有限差分方法和数值积分方法在纺织材料中对热湿传递模型求解的作用.对于不同材料的多孔织物介质中的温度、水蒸气浓度和含水量进行了数值计算与比较.数值模拟结果及其分析表明了数值算法的有效性.Based on the reliable calculation of numerical value, the powerful function of an illustrating and easily learned language system, Matlab can be used to compute numerical solutions for a dynamic model of heat and mois- ture transfer with condensation in porous fabric. The action of Matlab with finite - difference and numerical integra- tion for solving the heat and moisture transfer model in textile materials is also described in the paper. The distribu- tions of temperature, moisture concentration and water content in the porous fabric for different materials are numer- ically computed and compared. The consistency between numerical simulation results and experimental data demon- strates the effectiveness of the proposed numerical algorithm.
