摘要：

We investigate the structure of colloid-polymer mixtures by calculating the structure factors for the Asakura-Oosawa model in the PY approximation. We discuss the role of potential range, polymer concentration and polymer-polymer interactions on the colloid-colloid structure. Our results compare reasonably well with the recent experiments of Moussaid et al. (MOUSSAID A., POON W. C. K., PUSEY P. N. and SOLIVA M. F., Phys. Rev. Lett., 82 (1999) 225) for small wave number k, but we find that the Hansen-Verlet freezing criterion is violated when the liquid phase becomes marginal.
