Anderson-Grneisen参数、热膨胀系数与压强的普遍关系

THE PRESSURE DEPENDENCE OF THE EXPANSIVITY AND OF THE ANDERSON-GRNEISEN PARAMETER IN THE GENERAL CONDITION

本文首先从理论上导出A derson-Gruneisen参数与体积弹性模量对压强的一阶导数之间及体积弹性模量与压强之间的普遍关系。然后在此基础上进一步导出Anderson-Gruneisen参数、热膨胀系数与压强之间的普遍关系。

In this paper, the general relations between the Anderson-Gruneisen parameter and the first derivative of the bulk modulus with respect to pressure and between the bulk modulus and pressure are derived theoretically. And from these relations, we further obtain the pressure dependence of the Anderson-Gruneisen parameter and of the coefficient of thermal expansion under general conditions.
