孔隙通道 meaning in English

pore channel

The cross-sectional areas of the pore openings vary along their length .
孔隙通道的横截面面积沿其长度方向变化。
The diffusion coefficient is scaled up with porosity percent . the gas diffusion is simulated using diffusion equation in fractal porous media . dispersion process in porous media is analyzed and simulated by use of monte carlo method in this paper
第四章将蒙特卡罗(随机模拟)方法应用于多孔介质中的物质传输过程,采用通道逾渗模型，对不同孔隙通道联结率下的弥散规律进行了分析。
The change of big pore section shape has more influence on soil water movement , but in small pore channels , the influence is small , in addition of pore section shape , it can get better prediction of unsaturated hydraulic conductivity
粗大孔隙通道的截面形状及变化对水分运动影响较大，较细空隙通道截面的形状对水分运动影响较小。修正孔隙截面形状对水分运动的影响，进一步考虑孔隙截面形状因子对土壤水分运动的影响，可以得到对土壤水分运动参数更正确地预测。
