本文研究了高电荷不对称胶体悬浮液中粒子-反离子团簇的形成过程。这种聚集的发生是通过颗粒的电泳迁移率来探测的，即，借助于传输特性。结果表明，在外加电场作用下表现出来的有效电荷是将Debai-Huckel-Bjerrum理论推广到高电荷态胶体的重整化电荷。
The formation of particle-counterion clusters through electrostatic interaction is studied in this work for a highly charge asymmetric colloidal suspension. The occurrence of such clustering is probed by the particle electrophoretic mobility, i.e., with the aid of a transport property. The results show that the effective charge manifesting under the presence of an external electric field is the renormalized charge predicted by an extension of the Debye-Huckel-Bjerrum theory to the fluid state of highly charged colloids.
