本研究中进行了间歇絮凝实验，以测试先前开发的粒度分布变化模型。在每个实验中，时间是唯一的自变量。在实验之间，速度梯度、颗粒浓度和化学条件是独立变化的。对粒度分布进行了详细测量，并对每个变量引起的变化程度进行了量化。如果模型中允许部分沉淀，则时间、浓度和化学条件的影响得到了合理的解释。该模型大大高估了速度梯度的影响，表明目前对流体运动引起的粒子碰撞的理解很薄弱。 包括23个参考文献、图表。

Batch flocculation experiments were performed in this study to test a previously developed model for the changes in particle size distribution. Within each experiment, time was the only independent variable. Between experiments, the velocity gradient, particle concentration, and chemical conditions were varied independently. Detailed measurements of the particle size distribution were made, and the extent of change caused by each variable was quantified. The effects of time, concentration, and chemical conditions were reasonably well explained if partial sedimentation was allowed in the model. The effect of the velocity gradient was greatly overestimated by the model, suggesting that current understanding of particle collisions caused by fluid motion is weak.
