摘　　要：利用Matlab软件对煤焦燃烧过程中的SEM图像进行分析处理,得到了煤焦表面孔的二值化图像及其对应矩阵,并针对二值化数字图像的特点,借助分形理论详细论述了计盒维数计算SPFD的原理及方法,为研究燃烧过程中煤焦表面结构变化提供了一种计算方法。The overall process of the complex chemical reaction in the coal combustion can be learned by studying the changes of SPFD. The 2-value digital image and matrix about the surface pore were studied by applying Matlab to analyze the SEM photographs of char samples during combustion. In accordance of the property of 2-value digital image, the principle and method of calculating SPFD adopting box-counting dimension were minutely discussed basing on the fractal theory. This article provides a kind of calculating method for the study of the surface structure changing in char combustion process.
