文摘In this paper, a molecular aggregation function which represents the degree of molecular aggregation is derived based on statistical mechanic method. Then,a truncated vinal equation is modified by the molecular aggregation theory. The proposed extended equation of state gives good representation of the PVT properties of saturated vapors for some strong polar fluids including water, alcohols and carboxylic acid etc.
