原子相互作用势对弹性模量随压强变化规律的影响研究

摘要

Based on the interaction potential among particles and the isothermal bulk modulus ,we had discussed the rule of pres‐sure dependence of the isothermal bulk modulus with Born‐Mie potential and Born‐Mayer potential and Harrison potential .The conclusions shows that calculated results with Harrison potential were in good agreement with the available experimental data .%从体积弹性模量与原子相互作用势的关系出发，分别利用Born‐Mie势、Born‐Mayer势和 Harrison交叉排斥势函数来讨论弹性模量随压强变化的规律，结果表明，用Harrison交叉排斥势函数得到的理论预测值与实验结果吻合得很好。
