在岩矿鉴定工作中,迫切须要准确的测定矿物的光学数据,尤其是矿物的准确折光率数值更属重要。但就薄片内直接测定矿物折光率的问题迄今尚存在一定困难。在此拟就弗氏台上利用薄片内矿物的裂隙或解理测定均质体矿物折光率的方法探讨如下: 在弗氏台上利用矿物全反射角来测定折光率 In rock and mine appraisal work, it is urgent to accurately measure the mineral optical data, especially the accurate refractive index of minerals is more important. However, the direct determination of mineral refractive index within the sheet so far there are still some difficulties. Here on the Freescale stage on the use of thin-film minerals in the cracks or cleavage method of determination of the refractive index of the homogeneous body minerals are discussed as follows: Refractive index
