| 摘 要： | 絮体的形态学研究是当今热点,本文便对近些年混凝过程的分形理论研究进行了概述.由于混凝中絮体的形成是一个随机碰撞——结合过程,由初时粒子碰撞结合逐步长大,决定了它在一定范围内是具有分形的两个重要特征:自相似性和标度不变性,也就是说絮体也是一个分形结构.

| Abstract: | Study of flocculation morphology has been a spotlight in recent years.The latest achievements in the field of coagulate based on fractal theory are reviewed.Flocs are recognized as fractal objects with a self-similar structure because their formation is a random process from an initial particle to a larger one. |

| Keywords: | flocs simulation fractal dimension |
