| 摘 要： | 基于相界面质量、动量平衡定理，对矿粒在气泡表面粘着行为进行了动力学分析，考虑了范德华作用力以及双电层作用力对粘着过程产生的影响，建立了感应时间模型，该模型与前人实验结果吻合较好。

| Abstract: | Based on jump mass balance and jump momentum balance, the hydrodynamic behaviour is discussed for adhesion of a mineral particle on a bubble, including the effects of London-van der Waals forces and electric double layer forces, and a model for induction time is developed. The predicted results are well compared with previous experimental data. |
