The physical substantiation is given the new equation of state used for calculation of equilibrium characteristics of supercritical fluids. Feature of the given method is, first, possibility to use it in all working area, including area of strongly developed fluctuations of density, secondly, simplicity of the settlement scheme. Last circumstance is caused by that the equation of a condition underlying the settlement scheme, unlike the known equations of a condition satisfying to a scale hypothesis, does not contain nonlinear individual parametres.
