中文摘要：

综述了实验揭示的水流剪切条件与絮团特征参数（尺寸、分形维数）之间的关系,总结了同向絮凝的机理研究,并就絮凝实验研究过程中的一些问题提出了建议。

英文摘要：

In this review,experimental investigation on the relationship between the characteristic parameters of floc（such as size,fractal dimensions） and different flow shear conditions,and mechanism of orthokinetic flocculation are summarized.A proposal for the future experimental study on flocculation of cohesive sediment is prospected.
