【摘要】 从碱卤晶体总相互作用势能出发，得到了一个状态方程。在不存在压致转变的压力范围内，该方程能够很精确地描述室温时碱卤晶体在高压下的等温压缩行为。还进一步讨论了体积弹性模量和其压力导数之间的关系。计算结果与实验结果符合得很好。更多还原

【Abstract】 In this paper,starting from the total interaction potential function among ions,theequation of state and the relations between B_o and B’_o,B"_o are derived for alkali halide crystals.Thecalculated value is in good accord with the experimental value. The results show that the equationof state is suitabie to describe the isothermal compressing behaviour of alkali halide crystals atroom temperature and high pressure in the state without pressure-induced transitions.更多还原
