摘　　要：　用MonteCarlo方法模拟了带电胶球系统,采用接受率方法获得该体系的耗尽势,再对耗尽势取数值微分得到耗尽力,通过对耗尽力与库仑力的对比分析,初步建立起在两带电大胶球比较靠近范围内耗尽力仍起明显作用的带电胶球模型.The depletion potential of charged colloidal system is studied by the Monte Carlo method through the Acceptance Ratio method, and the depletion force can then be calculated by numerical differentiation of the depletion potential. Based on the simple charged colloidal model presented, the numerical results show that the depletion forces are still play an important role between the charged spheres.
