碳酸钙包覆颗粒的分形表征及维数计算

Fractal Token and FD Calculation of CaCO_3 Coated Particle

基于分形理论,利用数字图像处理软件Photoshop对碳酸钙包覆颗粒的SEM照片进行了处理。使用计算机最小图形单元——像素为数据单位,利用周界直径关系法和周界面积关系法分别对碳酸钙包覆颗粒的边界分维进行了计算,并利用截面约定方法给出了其三维分形维数值。

Using Image Processing Software （IPS） Photoshop, this paper handles the Scan Electron Microscope （SEM） photos of CaCO3 coated particles based on fractal theories.Pixel,the least image element is taken as the data unit,P-D and P-A methods are used to calculate the border fractal dimension of calcium carbonate coverture particles in this paper.At the last,3-D fractal dimension value of the particle is given according to section agreement method.
