| 摘 要： | 针对皮肤各层结构主要由细胞和细胞间液构成的特点提出了可行的3层多孔介质物理模型,根据不同层的具体特点建立了相应的浓度和能量数学方程.利用浓度方程对模型进行了浓度分析求解,和编程计算了在不同灌流率、传质系数和各层厚度下对浓度的影响.与传质系数实验所得结果相比较,结果一致.

| Abstract: | Based on characteristics that different layers of skin mainly consist of cells and liquid between cells,a feasible three layer physical model,which had used methods of porous medium,was put forward. Mathematic equations about conversation of consistency and energy were founded according to peculiarities of different layers. Analytical solutions were given by using the equations of consistency. On the condition of different blood flow rate, coefficients of mass transfer and thickness of layers,the changes of consistency were calculated by programming. These results are consistent with the results coming from experiment of mass transfer coefficients. |
