| 摘 要： | 有机同系物的折光率ｎＤ与其分子量Ｍ和重复单元数ｎ的关系可表示为Ｍ／ｎＤ＝ａ＇＋ｂ＇ｎ．其中ａ＇、ｂ＇为经验常数，将有机同系物测定折光率ｎＤ代入上式，进行（Ｍ／ｎＤ）－ｎ线性回归分析，结果表明，４１个有机同系列的回归方程，相关系数ｒ全部大于０．９９９。

| Abstract: | It can be expressed as M/nD=a'+b'n for the relationship among the refractivity(nD),molecular weight(M)and number of repeating unit(n)in an organic homologs,where,the a'and b'are empirical constants. Making linear regression analyses between the M/nD and n with the experimental refractivity of organie homologs,we got the result that the correlation coefficients r all are more than 0.999 for the 41 organic homologous series. |
