引言 矿物学家和岩石学家在研究岩石薄片时,常用偏光显微镜测定矿物的光学性质,其中重要的一项就是矿物之间或矿物和周围介质之间的折射率差别。为此,本世纪初以来就使用了Becke和Schroeder Van der Kolk的经典方法。
Introduction Mineralogists and petrochemists often use polarized light microscopy to determine the optical properties of minerals when studying rock flakes. An important part of this is the difference in refractive index between the minerals or between the minerals and the surrounding media. For this reason, classical methods by Becke and Schroeder Van der Kolk have been used since the beginning of this century.
