Associated features, including a narrow reflectance minimum for a wide range of angles of incidence, are potentially useful.

这种材料的一些相关特性具有潜在的应用，例如对于较大入射角范围的窄边最小反射率。

The local maximum and minimum in reflectance spectral curve, corresponding to reflectance apex and Absorption apex, can be used to retrieval also, but effective matching strategy should be adopted.

基于光谱特征的检索可以通过提取反射和吸收光谱、光谱特征匹配的方法进行；
