悬浮粒子动力学是流体力学和胶体科学交叉边缘处的新兴交叉学科，有广泛的应用前景．本文对在许多工业生产中有重要应用价值的悬浮粒子的沉降与悬浮粒子的碰并（即聚集、团聚、聚沉、凝并）．做了系统的总结。重点在作者本人的工作． Suspended particle dynamics is an emerging interdisciplinary field at the intersection of fluid science and colloidal science, and has wide application prospects. In this paper, the sedimentation of suspended particles, which have important application value in many industrial processes, collide with the suspended particles (ie, aggregate, agglomerate, aggregate, coagulate). Made a systematic summary. Focus on the author’s own work.
