摘　　要：通过Monte Carlo模拟,研究在巨正则系综和正则系综两种情况下胶体的排空作用,运用接受率法得到了一些数值结果.结果表明,在相同的平行板约束条件下,巨正则系综情况下胶体的排空作用和正则系综中胶体的排空作用都会受到系统的化学势影响,但巨正则系综情况下胶体的排空作用受到化学势的影响比正则系综情况下受到的影响大得多.In the grand canonical ensemble and the canonical ensemble,the colloidal depletion interactions was investigated through Monte Carlo simulation, and using acceptance ratio method,some numerical results was obtained.These numerical results shown that the colloidal depletion interactions are affected by the chemical potential of the grand canonical ensemble and the canonical ensemble in the same parallel plates constraint conditions,the effect from the chemical potential in the grand canonical ensemble are larger than in the canonical ensemble.
