基于图像处理的土石类多孔介质结构特征分析

摘要

多孔介质结构特征研究是多孔介质应用的基础，决定着多孔介质内部流动、传热、应力应变和化学反应等过程。文章以碎石地面为例，说明IPP（Image-Pro Plus）软件分析获得多孔介质各种结构特征参数的使用方法。利用该软件提取了土壤、沙粒、石堆的颗粒和空隙的平均直径及各种分维数，分析对比得到了相关规律，为进一步深入研究广泛的多孔介质结构特征及规律提供了方法和指导。%The application of porous media depends on its structure features which determine the flow, heat transfer, stress, strain and chemical reaction in porous media. In this paper, taking the gravel floor as an example, the method of using IPP (Image-Pro Plus) software to analyze and obtain the different structure characteristic parameters of porous media is described. The average diameter of particles and pores and fractal dimensions are analyzed and extracted by IPP 6.0, from soil, sand and gravel floor. And related results are obtained through the comparative analysis, which provides the way and instruction for further studying the pore structure characteristics and laws.
