摘要：
We present a new scaled equation of state adequately describing the P-ρ-T data for fluids near the vapor-liquid transition point and compare this equation to the Schofield parametric equation of state. A comparative analysis of the approximation of data for He4, C2H4, and H2O in the critical region shows that both these equations correctly describe the behavior of thermodynamic functions asymptotically close to the critical point.
