摘要
本文采用离散分形布朗增量随机场（ＤＦＢＩＲ）模型对煤样微观结构的显微图像做了分形定量研究。由于分形的表面必然会产生分形的灰度图像值，故通过提取图像各像点的灰度值，计算（ＤＦＢＩＲ）场模型的分形维数，得出了不同类型煤样微结构图像的分形维数。从而为扫描电镜用于定量研究煤结构探索了新的途径。
This paper researches the fractal of the scanning electron micrograph of coal samples by Discrete Fractal Brownian Increment Random Field(DFBIR).Due to fractal surface corresponding to the fractal gray scale of the graph, the fractal dimension of DFBIR is calculated by means of extracting the gray scale of each image point of the electron micrograph.Therefore,fractal dimensions of the electron micrograph for different kind of coal samples are gotten.This method is a new way to quantity microstructure of coal samples by scanning electron microscopy.
