摘要：

We propose a perturbative modification of the Carnahan-Starling equation of state for a binary hard-sphere mixture which brings its virial coefficients into better agreement with recent numerical findings. The resulting analytic equation of state predicts a demixing transition whose spinodals and binodals are in qualitative agreement with recent numerical and experimental findings.
