Уравнение состояния, разработанное на основе анализа поведения изобарной теплоемкости в критической области

Abstract

On the basis of the phenomenological theory of critical phenomenas and a Benedek hypothesis the scale equation of state in variables density and temperature for an asymptotic neighbourhood of a critical point is output. The offered equation of state meets all requirements of a scale hypothesis and coincides on the structure with the scale equations of state constructed within the limits of a method of pseudo-critical points. As gauge at build-up of a nonparametric scale equation of state for the first time it is offered to use scaling component of an isobar heat capacity. The offered equation of state meets all requirements of a scale hypothesis and coincides on the structure with the scale equations of state constructed within the limits of a method of pseudo-critical points. Use as independent variables of density and temperature allows to use the offered approach for build-up of the wide-band equations of state satisfying to a scale hypothesis.

На основе феноменологической теории критических явлений и гипотезы об одинаковом характере поведения изобарной теплоемкости на критической и околокритических изохорах в асимптотической окрестности критической точки выведено масштабное уравнение состояния в переменных плотность и температура. В качестве масштаба при построении непараметрического масштабного уравнения состояния впервые предложено использовать скейлинговую составляющую изобарной теплоемкости. Предложенное уравнение состояния удовлетворяет всем требованиям масштабной гипотезы и совпадает по своей структуре с масштабными уравнениями состояния, построенными в рамках метода псевдокритических точек. Использование в качестве независимых переменных плотности и температуры позволяет использовать предложенный подход для построения широкодиапазонных уравнений состояния, удовлетворяющих масштабной гипотезе.
