摘要

摘要: 用统一的排列模型研究石墨在高压下的状态方程。能量由冷能、晶格振动和电子的热贡献三部分组成。利用上述模型计算了石墨的膨胀曲线及石墨的冲击压缩Hugoniot曲线，当V0＝5.29 cm3/mol时，计算结果与Morgan实验结果一致。

Abstract: In this paper we have studied equation of state of graphite and diamond under high pressure with a unified scaling model. Simple additivity of the energy terms is assumed and the cold pressure curve is a modified Birch form. The lattice thermal effects can be computed by the Einstein model while the electronic contributions are represented by the low temperature form of heat capacity and energy. Using the above model, we have determined the expansion curves and Hugoniot curves of graphite under different initial conditions.
