A novel composite model is put forward for humidity-sensitive material based on Maxwell-Garnett and effective medium theory. The analytical expression of the relation between effective refractive index and relative humidity is shown with different absorption factors and porosities. The larger the absorption factor is, the higher the refractive index is.

As a result, if the iridescence is produced by thin-film interference, not only the thickness of lamellar structure must be defined within a certain nanometer, but also the refractive index need to be different between lamellar structure. In other words, the chemical composition, refractive index and thickness of exsolution lamellae need form to trinity, such as labradorite, albite, andradite and orthoamphibole. If the iridescent color is produced by grating-diffraction, the lamellar structure just needs to be arrayed regularly, the spacing of the edges of lamellar structure needs to be regular and narrow, but not necessarily within the range of the wavelength of visible light, such as shell of abalone, pearl and opal.

So , it comes to the conclusion that the value of the natural refractive index should be inputted in data processing if possible and a value larger than 2.0 should be believably chosen as the inputted refractive index if the natural refractive index of the measured particles is unknown .

Analyses show that refractive index changeinduced by thermal effect is similar to the change induced by other effects for linearabsorption,if laser pulse width is far less than the characteristic time of sample,i.e.refractive index change is directly proportional to spatial part of incident pulse laserintensity,so time averaged nonlinear refractive index can be defined.

Based on the molecular topological theory, a modified group dyeing indexL is introduced. It is used in the study of refractive index of the ketones and ethers. Relationship between the refractive index and molecular structure of 57 ketones and ethers is studied by using quantitative structure-property relationship technique. The reasonable molecular modeling equations are obtained by multiple regression for the prediction of the refractive index of ketones and ethers.
