摘要
运用扫描电子显微镜对所选三种煤样微观孔隙结构的观察研究,总结出不同煤种内部孔隙的分类及孔隙的分布情况,进一步研究不同孔隙结构对燃烧的影响。提出了一种新的重构方法,利用Matlab软件对烟煤SEM图像进行分析处理,运用分形理论总结得到孔隙结构的分形特征,然后自编程序对其二维结构进行重构,最后得到重构图像及各参数与真实图像及各参数有很好的相似度。重构结果表明,该方法与真实实验具有很好的吻合,其为研究单颗粒煤及其它多孔材料内部孔隙结构提供了一种方法。
Observed using scanning electron microscopy studies of three coal samples selected microscopic porestructure, summed up the distribution of the classification of different coals internal pores and pore further study theeffects of different pore structure on combustion. This paper presents a new reconstruction method, using matlabsoftware bituminous SEM image analysis and processing, the use of fractal theory summed to obtain the fractal char-acteristics of the pore structure of the program and then reconstruct their self-dimensional structure, and finally gotreconstructed image and the real image and the parameters and the parameters have a good similarity. Reconstruc-tion results show that the method has a real experiment in good agreement, which provides a method for the study ofsingle particles of coal and other internal pore structure of porous materials.
