摘　　要：以H - (CH2 ) n-C≡CH型同系物结构重复单元数值连续变化为模型 ,获得了描述该同系物凝聚型物理性质递变规律的数学表达式 :P =(a0 +a1n +a2 n2 ) /(1 +b2 n2 )。通过非线性回归分析 ,得到回归方程 ,结果表明该同系物的凝聚型物理性质与重复结构单元数值之间满足上述关系式 。With the model that the number or repeating units of the H-(CH 2) n-C≡CH type homologous series varies successively,they were able to be described as the following equations:p=(a 0+a 1n+a 2n 2)/(1+b 2n 2).Significant correlation was found between the physical properties of homologous compounds and their number of repeating units in this model.
