摘要 用Monte Carlo方法对处于两平行带电硬板约束下的大小带电胶球系统进行了模拟,根据对大胶球表面小胶球密度的统计,由密度积分方法获得大胶球所受的排空力。其所受的库仑力,用有效截距法做了处理。通过排空力和库仑力的对比分析,发现排空力和库仑力的合力存在长程吸引。 The depletion force between two big charged colloidal spheres in charged colloidal system which under charged geometrical confinement is investigated by using local density integration method through Monte Carlo simulations, and the Coulomb force between the two big spheres would be deal with truncation method. The numerical results show that sum of the two effective interactions long-range attractions exist.
