摘要
电镜片研究显示絮凝体的表面和内部具有高度不规则性,絮凝体的形成过程具有分形特征。通过实验研究絮凝体的特性和分形维数之间的关系,分析了絮凝体的分形特征,发现可建立一种非整数维数数学模型去定义具有复杂、不规则形状的絮凝体。实验结果表明,可以通过监测絮凝体的分形维数来控制絮凝过程。
The microscopic studies of flocs indicated that flocs＇ surface and interior presented highly irregularity. The research also indicated that flocs＇ structure and establishment possessed fractal characteristics. This paper studied relationships between flocs＇ characteristics and fractal dimension via some experiments. It also analyzed factors about flocs＇ fractal characteristics. Through the analysis of flocs＇ fractal structure, we could use a non - integral dimension to propose a sort of mathematical frame to define these grains, which had complicated and irregular shapes. The results were almost certain that we could control the flocculation process by meteraging of the flocs＇ fractal dimension.
