“…Note that these EOS based on a Taylor series expansion are restricted to a narrow range of compressions unless higher terms are taken into account. [9] As shown by Gaurav et al, [10] the first two terms of the Taylor expansion of the Eulerian strain and natural strain are identical, hence both EOS should yield identical results for low compression. Note that neither of the two series is convergent for n → ∞ which may cause serious problems for high compression.…”

“…2 и 3, можно согласиться с этим в случае Ar, но не в случае Ne. В работе [11] анализируются 5 феноменологических уравнений состояний [7,8,45,49,50] для твердых тел (Ne, Ar, Cu, Al, LiH и MgO) при очень сильном сжатии, причем больше всего критикуется EOS [45], как метод его получения, так и результаты расчета.…”

“…При комнатной температуре уравнение состояния кристаллического Ne экспериментально изучалось с ис- Теоретические описания изотерм в широкой области давлений основываются на полуэмпирических уравнени-ях состояния с параметрами, определяемыми при нор-мальном давлении [7][8][9][10][11][12][13][14][15]. Наиболее успешным считается уравнение состояния Винета [8], для которого необходи-мо знание 4 параметров: 1) изотермического объемного модуля при нулевом давлении; 2) его производной по давлению; 3) объема при p = 0 и 4) термического расширения при p = 0.…”

“…The Vinet equation of state (EOS) [1] based on the Rydberg potential function [2] has been widely used [3][4][5][6][7][8][9][10][11] in spite of its main shortcoming regarding the extreme compression behaviour of solids in the limit of infinite pressure [12,13]. This shortcoming was rectified [10,14] by generalizing the Vinet-Rydberg EOS.…”
