摘要
以一阶分子连接性指数１χ为分布变量，研究了链烷烃ＳＲＫ状态方程参数与１χ的关系。结果表明这些参数与１χ有着良好的相关性，这些关系可用于石油馏分中链烷烃组成的预测和与链烷烃有关的连续热力学计算、研究及状态方程参数估值。
The relationships between parameters of SRK state equations and molecular connectivity index 1χ are studied with 1χ as distribution variables.The results indicated that there are good correlations between these parameters and 1χ .The correlations can be used to predict compositions of paraffins of petroleum fractions,studies and calculations concerned with the continuous dynamics of paraffins,and estimations of these state equation parameters.
