折射率色散 meaning in English

dispersion of refractive index

The dispersion caused from the chromatic aberrations of lens is smaller than that from diffraction effects of it
与衍射效应产生的色散相比，透镜本身的折射率色散很小。
The results indicate that ( a ) before heat treatment , with the increasing of substrate temperatures , content of lower valency ( tij + ) decreases , the stoichiometric proportion of o / ti in all samples is about 2 ; the films have amorphous incompact columnar fiber structure , and with the increasing of substrate temperature , the size of columnar fiber increases ; the films have good hyalescence in visible range and great absorbability at the wavelength of 350nm ; optical constants of the films are calculated from the transmittance spectrums in visible range by mathematical analysis of the orders of interference , the results show that the refractive ind
研究结果表明， ( a )热处理前，随着基片温度的增加，薄膜中的低价氧化钛含量逐渐减少，化学计量比趋于o ti = 2 ；薄膜具有非晶态不致密的柱状纤维结构，柱状纤维的尺寸随基片温度的升高而增加;薄膜在可见光范围内透明，在波长为35onzn时严重吸收，利用干涉级次法分析了薄膜的光学常数，结果表明，薄膜的折射率随基片温度的升高而增加，根据计算结果得到了tioz薄膜在不同基片温度下的折射率色散曲线。
