摘　　要：应用氩模型理论微分方程和气体不平衡状态理论方程导出气体纯质的定压摩尔热容理论式,创立3个定理及一个定则(rule),特别是其中的1个定理:"n值相同的不同结构类型分子中>CH2的热容惯性因子值相等",在提高上述理论方程的理论水平和应用价值两个方面都有很大的作用。在很多情况下,仅须知道熔点Tm和沸点Tb就可快捷地准确预测C0pg。从理论上看,本法物理意义明确,适用范围广泛,优于文献中各式,从精确度看比国际上权威著作中推荐的的经验式高3倍以上。事实证明是一个实质性的进展与突破。A theoretical equation has proposed for calculation of gaseous heat capacity Cpg^0 which can be derived from the differential equation for a model of argon gas and from an theoretical equation for the nonequilibrium state of gases （TENSG）. Three theorems and one rule are obtained by logical reasoning. Especially, one theorem in them, that the value of inertia factor of heat capacity 〉 CH2 is equal cules, is great useful in the advance of the theoretical level and in the same value of n of different structural moleapplicable values above theoretical equation. In the most cases, the accuracy of calculating Cpg^0 require only values of melting point and normal boiling point. From the theory, the physical meaning of the method is clear and define. ZHANG Kewu＇s technique is the simplest broadly applicable method and far better than all other published methods. From the accuracy, these results are over 3 times higher than the most famous formula recommended in international and authoritative literatures. The present equation is of great significance in the development of statistical physics and an important breakthrough in basic
