摘要
将张克武提出氩模型微分方程创立的气体不平衡状态理论方程推广应用于液体,导出液体定压比热理论方程。经以极性与非极性等32种结构类型220种纯质986个实验数据检验,平均误差仅0.85%,显著优于前人公式,有重要的理论意义与广泛的应用价值。
A Theoretical equation for nonequilibrium state of gas is here extended to the liquid. Thus a theoretical equation of isobaric liquid heatcapacity is proposes as C P1 =k c[T 1.47 /(T+140)] n(5) this equation can be applied to both poalr & nonpolar liquids. The average error from 986 experimental data is 0.85%, based on 220 compounds of 32 structural types. Its accuracy is about 10 times than that of Rowlinson-Bondi method which is optimal in this area & recommended by Reid et al. It is far better than all other methods in the interature. The physical essence of Eq.5 is clear & definite so that we can obtain 4 rules by logical reasoning. these results show that our work is important break through in basic research.
