液体内电场对折射率的影响

从液体分子结构微观模型出发,首先利用诱导电偶极子的电场公式对液体分子所受到的内电场进行计算,计算得出修正系数K,对洛伦兹关系进行修正,从而得出液体分子排列的有、无序程度及排列方式与折射率的关系。从内电场角度解释热光系数的成因。

Influence of internal electric field of liquid on the refractive index

Based on the microscopic model of liquid molecular structure,this paper discusses the liquid dielectric polarization of optical frequencies.Adopting the electric field formulas inducing electric dipole,we calculated the inter electric field which affects the liquid molecular,and modified the Lorentz formula with the calculated result.K-factor’s estimated number is obtained;meanwhile,the relationship between the refractive index and the degree of orderly and disorderly arrangement of liquid molecular is partially drawn out.Moreover,this paper discusses the relationship between the thermo-optical coefficient and the orderly and disorderly arrangement of liquid molecular.
