摘要：

During the past few years, considerable effort has been devoted to understanding the character of the particle-solution interface using electrokinetic methods. Recent experimental work has uncovered striking discrepancies between experiment and the classical theory. Ion migration behind the shear surface is one mechanism postulated to explain matters. Accordingly, the theory was extended to include this mechanism and a numerical methodology was developed to solve the equations for particles in an oscillatory electric field. The results show considerable promise. Comparisons between theory and experiment indicate that allowing for surface transport can reconcile measurements of the mobility of individual particles with measurements of the dielectric behavior of a dilute suspension.
