运用晶体光学中光率体的理论，分析了非均质体宝石光学参数未定的刻面的光波振动方向及折射率值的变化规律，找到了仅由台面测定宝石未定光学参数的一种最简便的方法，为快速准确鉴定宝石奠定了基础
Based on the theory of optical body in crystal optics, the variation rules of the light vibration direction and the refractive index of the optical facets with indefinite optical parameters are analyzed. The most simple and convenient method Method, for the rapid and accurate identification of precious stones laid the foundation
