| 以表3所示110種硅烷和硅氧烷化合物作為樣本，采用基團貢獻法研究分子結(jié)構與摩爾折射度和摩爾體積之間的關系。利用實驗數(shù)據(jù)計算各化合物的摩爾折射度和摩爾體積，對每一樣本化合物分別采用式（3）和（4）以描述官能團種類和數(shù)量與化合物摩爾折射度和摩爾體積之間的關系，采用“麥夸特法+通用全局優(yōu)化法”的算法分別對摩爾折射度和摩爾體積方程組進行非線性回歸，得到各基團摩爾折射度貢獻值Gi和摩爾體積貢獻值Vi（表2）。利用回歸得到的各基團摩爾折射度的貢獻值和硅烷、硅氧烷或聚硅氧烷的分子結(jié)構，可計算得到各化合物的摩爾折射度。 |

As shown in profile 3 , and 110 kinds of silane and siloxane compounds as sample, The relationship between molecular structure and molar refraction and molar volume was studied by the group contribution method . the molar refraction and molar volume of all kinds of compounds were calculated by using the experimental data. the relationship between functional groups of species and quantity of compounds with molar refractivity and molar volume, were describled by type (3) and (4) for each sample compounds respectively. using "Marquardt + universal global optimization method" algorithm, for the molar refraction and molar volume equations are nonlinear regression respectively, the molar refraction contribution value Gi and molar volume contribution value Vi (Table 2) were obtained. Molecular structure by using the regression results of the molar refractivity contribution value and silane, silicone or silicone, can be calculated by the compounds of the molar refraction. |

| As shown in table 3 110 kinds of silane and silicone compound as a sample, the research group contribution molecular structure and molar refraction and the relationship between the molar volume. Use experimental data to calculate the compound molar refraction and molar volume, as well as for each of this compound were used respectively to type (3) and (4) to describe the functional group type and quantity and compound molar refraction and molar volume, the relationship between the use "wheat quarts method + general global optimization method" algorithm respectively on molar refraction and molar volume equations are nonlinear regression, obtains each group molar refraction contribution value Gi and molar volume contribution value Vi (table 2). Using the regress each group molar refraction contribution value and silane, silicone or gather any of molecular structure, we can calculate and gained the compound molar refraction. |
