摘要
本文采用中观观点,应用平均势能〈φ〉推出高温高压气体的物态方程,既可避免Haar-Shenker方程中某些含混之处,又可消除Lennard-Jones势能模型中某些决定性与随机性混淆的缺点,同时平均势能〈φ〉直接是温度和密度的函数,在计算上可以免除在不同密度区间选择不同势能的麻烦.
From the mezoscopic view of point and with the help of the average potential<φ>, this paper introduces theequation of state of gases at high temperature and pressure,which can not only avoid some ambiguity of Haar-Shenkerequation, but also eliminate the fault of mix-up of deterministicand stochastic in Lennard-Jones potential model .At the same time,the average potential<φ> is directly the function of temperatureaud density, avoiding the trouble of selecting different potentialsin various density intervals on calculation.
