摘要
根据有效介质理论，研究了材料的孔隙度对其反射光谱的影响，发现随着孔隙度增加，多孔材料的红外反射光谱呈现下塌趋势，通过比较ＳｉＯ２玻璃与多孔ＳｉＯ２玻璃的红外反射光谱检验了这一规律．
By using the effective medium theory,the influence of porosity on IR reflection spectra of porous materials was investigated'It was found that for the reflection spectra of porous materials there emerges a tendency fo collapse with increasing porosity,which was examined by comparing the IR reflection spectra of SiO2 glass with that of porous SiO2 glass.
