有机同系物性质的递变规律研究

以有机同系物结构重复单元数值连续变化为模型，得到同系物行质递变的两个基本规律：P=a+bn和P=c+kln(n+a/n+b),a,b,c,k均为常数，n为结构重复单元数值，P为同系物的物性。一般地，加和型性能遵守直线变化规律，而结构型和凝聚型性能遵守同系对数线性规律。

Regularity of physicochemical properties for homologous organic compounds

With the model that the number of repeating units of the homologous series varies successively, two fundamental relationships have been developed:P = a bn and P = c kln n a/n bwhere a,b,c,k all refer to the constants, n to the number of repeating units, P to the properties for ho-mogolous series. Generally, additive type properties conform to the linear relationship, and the structural - type properties and condened - type properties to the homologous logarithmic linear relationship.
