Description of phase equilibria line in critical condition region
Annotation
The analysis of the modified Yang-Yang on the basis of mutually agreed lines of equations of elasticity and the saturation line, satisfying the scale theory of the critical point. For example, describe the pressure and density of argon in the saturated state approved scheme search system parameters mutually equations and show that the modified model of Yang-Yang allows you to play back line of phase equilibrium from the triple point to the critical with an error not exceeding the initial error of the experimental data. Detailed description of the algorithm and experimental work with tabular data, on the basis of which the search for the coefficients of the equation. Resulting in the system of equations can be used to calculate the reference curve for the development of large-scale and common equations of state.
