摘要/Abstract

摘要：在受两平行硬板约束，其中一块板带电且大胶球靠近带电板一侧的弱带电胶体系统中，采用四维超球面法计算系统的能量，通过接受率方法计算胶球与板之间的排空作用，并与不带电的硬球系统中相应结果进行分析对比，结果发现静电势能增强带电胶球与约束硬板之间的排空作用.

Abstract: In the colloidal systems confined by two parallel plates (one of which is weak charged),the author uses 4D hyper-spheres method to calculate the energy of the system and uses the acceptance ratio method to calculate the depletion interactions between a charged large-sphere and the plate.By analyzing and comparing with the results of the hard sphere system,it is found that electrostatic interactions can strengthen depletion interactions between the charged large-sphere and the confined plate.

Key words: colloid, hyper-sphere method, acceptance ratio method, depletion interaction, Monte Carlo simulations
