摘　　要：以H-(CH_2)_n-CN型同系物结构重复单元数值连续变化为模型假定,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=(α_0+α_1n+α_2n^2)/(1+b_2n^2),其中α_0、α_1、α_2、b_2均为常数,n为结构重复单元数值,P为同系物的凝聚型物理性质。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单元数值之间满足上述关系式,显示优良的相关性。With the model that the number of repeating units of the H - (CH2)n- CN homologous series varies successively, the condensed - type physical properties of this homologous series can be described by the following equations:p= (a0 + a1n + a2n2)/(1 + b2n2), where a0、a1、a2、b2 all refer to the constants, n to the number of repeating units, p to the condensed- type physical properties of homologous compounds. Significant correlation was found between the condensed- type Physical properties of homologous compounds and their number of repeating units in this model.
