摘要
对不同地区的天然沙对应天然水，及不同模型沙对应北京地区自来水的不均匀细颗粒泥沙进行了絮凝试验，并对试验资料进行了初步分析，提出了不均匀细颗粒泥沙的絮凝度Ｆ１与泥沙粒径的关系。
Based on the experiment on flocculation nonuniform fine sediment in the water from natural river and model sediment in the city water of Beijing area,the relationship between the size of fine sediment particle and flocculation intensity F, is given. This relation has important reference value to sediment transport mechnics and physical model.
