【Abstract】 Based on the discrete fractal Brownian incremental random field(DFBIR field),a generalized fractal model which is suitable for quantitatively analyzing the surface morphology of powder partical is proposed.Its features and the realtime estimating method are studied.With the help of image analysis system,the secondary electron image of powder partical is investigated by using 3_FD analyzing technology proposed,the shap of particle,the roughness of powder partical surface.The result shows that,by means of the FD average value,FD histogram and FD image,the roughness of powder partical surface,the statistical distribution features can be quantitatively described.更多还原
