【摘要】 以有机同系物结构重复单元数值连续变化为模型,得到同系物性质递变的两个基本规律:P=a+bn和P=c+kln((n+a)/(n+b)),a,b,c人均为常数,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。更多还原

【Abstract】 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.更多还原
