【摘要】 对由大小胶球组成的系统,联合Monte Carlo方法与接受率方法研究了胶体系统中大胶球间的排空作用.通过对比4种不同半径比值的大胶球间的排空作用发现,当改变大小胶球的半径比时,大胶球间的排空作用是显著变化的,半径比大的排空作用强.更多还原

【Abstract】 The depletion forces in binary colloidal systems are studied by Monte Carlo simulations and acceptance ratio method.Compared with the depletion forces of 4 kinds of size ratio of large-to small-sphere,the numerical results show that the depletion interaction is affected by the size ratio: the larger the size ratio is,the stronger the depletion effect will be.更多还原
