Аннотация:The supercritical domain of the phase diagram of a substance is investigated. The dependence of the line of the stability minima and of the line of the particle number fluctuation maxima on the isotherms on the type of equations of state is determined. The connection between the fluctuation value near the critical point and the value of the compressibility at the critical point is found. This analysis showed that the Van Laar type of equation is the most effective among three-parameter equations of state for the description of the supercritical domain.
