直链饱和一元醇物理性质递变规律研究

摘要

With the model to the effect that the number of repeating units of the homologous series varies successively, they are described as the following equations: P＝(a0+a1n)/(1+b1n)，where a0, a1,b1 all refer to the constants, n to the number of repeating units, P to the physical properties of homologous straight-chain single fatty alcohols compounds series. Significant correlation is found between the physical properties of homologous straight-chain single fatty alcohols series and their number of repeating units in this model.%以直链饱和一元醇同系物结构重复单元数值连续变化为模型假定，获得了描述直链饱和一元醇同系物物理性质递变规律的数学表达式:P＝(a0+a1n)/(1+b1n)，其中a0, a1,b1均为常数，n为结构重复单元数值，P为直链饱和一元醇同系物的物理性质. 通过非线性回归分析，得到回归方程，结果表明直链饱和一元醇同系物的物理性质与重复单元数值之间满足上述关系式，均显示优良的相关性.
