摘要
采用Barker-Henderson软核微扰理论的方法改进马丁-侯状态方程,在“多方阱”微扰势的基础上引入一简单的“软排斥”势,导出了方程体积参数b与温度的函数关系以及新的常数的计算公式。使马丁-侯方程各参数的物理意义得到进一步解释,初步计算表明改进后的马丁-侯方程的计算精确度有所提高。
Barker and Henderson′s soft core perturbation theory is used to improve the Martin Hou equation of state. In addition to multi square well perturbation potential a soft repulsion reference potential is employed and an approximate expression of soft core diameter as a function of temperature is obtained. The results calculated from the equation of state are in good agreement with experimental data.
