摘要:

利用减压渣油及其超临界流体萃取分馏馏分的基本性质数据，由多元线性回归分析法得到了结构参数的关联式。并给出了在缺乏元素分析的条件下，渣油氢含量的预测式。模型简便可靠，有较大的实用价值。

Abstract:

By multivariate linear regression analysis method, the correlation of structural parameters was obtained from the basic property data (H/C atomic ratio, molecular weight, density) of residues and their fractions under ultra - critical condition. The predi
