摘    要:将由氩模型微分方程出发创立的气体不平衡状态理论方程推广应用于凝聚态物理学性质的研究中,导出液体定压热容Cp,1理论方程,并创立3个定理,据此在很多情况下,仅需纯质的熔点Tm,沸点Tb就能准确地计算出Cp,1.是百年来凝聚态物质热容理论研究中的重大突破.公式的精度比2001年Poling教授,Praunitz院士推荐的国际科技界最优公式(含CSP correlation等)高10倍以上,经极性与非极性等42种结构类型289种纯质的1086个实验数据检验,平均误差为0.82%,显著优于前人公式,有重大的理论意义与广泛的应用价值.

关 键 词:氩模型理论  气体不平衡状态理论方程  液体定压热容理论方程

Abstract:The theoretical equation for nonequilibrium state of gas derived from the differential equation for a model of argon gas is extended to the research of condensed matter physical properties. A theoretical equation of isobaric liquid heat capacity C_(p, 1) and 3 theorems are presented. So, in plenty of cases, C_(p,1) can accurately calculated by only using the boiling temperature point and the melting temperature point of the substance. It is important breakthrough in the theoretical research of heat capacity of condensed material. This equation can be applied to both polar and nonpolar liquids with an average error of 0.82% from 1086 experimental data, 229 compounds of 42 structural types. Its accuracy is about 10 times higher than that of one of the best methods(including CSP correlation, etc.), recommended by Pro. Poling, Academician Praunitz in international science and technology field. It is far better than all other published methods.
Keywords:a model theory of argon  theoretical equation of nonequilibrium state of gas  theoretical equation of isobaric liquid heat capacity
