The depletion interactions of colloidal suspensions in grand canonical ensemble

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.
