| 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问的排空作用.通过对比4种不同半径比值的大胶球问的排空作用发现,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. |
| 关 键 词： | Monte Carlo方法 排空力 接受率方法 |

| 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. |
| Keywords: | Monte Carlo simulation depletion force acceptance ratio method |
