摘要
对固体矿物和粉末矿物反射光谱进行了比较分析，并基于比值导数光谱法对石膏与绿帘石粉末混合物进行了光谱定量反演，提取出端元矿物的强线性波段，结合矿物特征吸收谱带信息，从反射率光谱、比值光谱及比值导数光谱等不同角度总结强线性波段的分布特征，初步判定强线性波段分布于端元矿物特征吸收谷附近的陡坡以及反射率光谱交点处.
Abstract
The spectra of mineral powder and mineral rock were compared and analyzed. A quantitative inversion based on DRS was performed on powder mixtures of plaster and allochite to extract the strong linear bands of each component separately. Combining with the absorption characteristics of endmember minerals, the distribution characteristics of strong linear bands on the reflectance spectra, the ratio spectra and the derivative of ratio spectra were discussed.
