金属矿物的反射率有如透明矿物的折射率一样,是鉴定及研究矿物时极其重要的光学常数。但目前在实际工作中还没有得到应有广泛的应用。虽然企图单凭精确的反射率来作为鉴定矿物的唯一依据是不可能的。因为不同的矿物,可具有相近似的反射率数值,同时不同产地和生成条件,特别是含有不同杂质的同一种矿物的反射力却有差异。可是毫无疑问金属矿物的反射力在鉴定和研究工作中应被列为首要的地位。因为既获知未知矿物的精确反射率时,便可使之局限在为数不多的其反射率极相近似的矿物行列中,只 The reflectivity of metallic minerals, like that of transparent minerals, is an optical constant that is of paramount importance in identifying and studying minerals. However, at present, it has not been widely used in practical work. Although it is not possible to attempt to rely solely on accurate reflectivity as the only basis for identifying minerals. Because different minerals may have similar reflectance values, the same time, different producing areas and generating conditions, especially with different impurities of the same kind of mineral reflectivity are different. However, there is no doubt that the reflection of metallic minerals should be paramount in the identification and research work. Because both know the exact reflectivity of unknown minerals, it can be limited to one of the very close ranks of the mineral reflectivity, only
