摘　　要：使用Ｖｏｇｅｌ方法和介质的色散关系，计算有机化合物在各波长的折射率ｎ（λ）．用Ｖｏｇｅｌ方法把化合物分子分解成碎片，加和得到化合物在某几个波长的折射率．假设化合物在所计算的波长范围内为正常色散关系，使用Ｖｏｙｅｌ方法得到的两个折射率，通过Ｃａｕｃｈｙ公式得到色散曲线，从而得到各波长的折射率ｎ（λ）．通过对有机化合物芪盐和高分子材料聚苯乙烯的各波长折射率进行计算，并与材料在某一特定波长的实际折射率对比，证明了计算结果比较准确．并对双折射液晶材料的折射率计算进行了探索．Using Vogel method and the dispersion relation, the refractive indices of the organic compound in all wavelength are calculated. The compound is decomposed to the pieces with Vogel method. And a few of refractive indices can be gotten by the sum of the constants of these pieces. Supposing the dispersion relation of the compound is the normal one, the dispersion curve can be gotten from Cauchy formula and two refractive indices,then the refractive indices in the all wavelength can be calculated. With this method, the refractive indices of the stilbazium salt compound and the polystyrene polymeric material in all wavelength has been calculated. Comparison between calculating and the real value of a refractive index at same wavelength shows that the calculating value is accurate.Furthermore the refractive indices of the liquid crystal having the character of two refraction have been calculated.
