| 摘 要： | 采用电子扫描显微镜和图像分析仪研究了我国三种典型的磷矿颗粒的表面结构，并提出了分形模型。由于沉积性磷块岩存在着自相似性，所得到分数维值可进一步预测磷矿颗粒内的磷灰石团粒分布率。同时对反应活性与表现分形间的关系也进行了探讨。

| Abstract: | By using scanning electron microscopy and image processing system the surface structrue of three kinds of typical phosphate rock in domestic mine were investigated. It was in turn to propose a fractal model to describe it. As there exist the self-similar characteristic,the fractal dimension values can predict inside porosity of the rock particles. The relation between surface fractal and reactiveties were also discussed. |
