摘　　要：针对金属断口纵剖面线（Profile）分形图的RSC特性，应用S600数字图像处理系统对其微分曲线进行了研究，提出了Profile的P谱模型与有关特征参数，用以全面描述Pro-file的分形特性，并应用于球墨铸铁断口Profile分形的统计分析和断裂机制研究中。Being aimed at the RSC (Reversed Sigmoidal Curves) characteristic of metal fracture Profile fractal chart, the differantial curve of fractal chart was studied by means of S600 data image processing system. A model of P-spectrum and some characteristic parameters which gave an overall description of the Profile fractal were proposed and used in the statistical analysis of the Profile and rupture mechanism reserarch of ductile iron fracture.
