摘要
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。
The relationship between vibration direction of light wave and refractive index at the polished faces of anisotropic gems were analysed by using the optical indicatrix theory. A simple methed for measuring undetermined optic parameters from a single plate of gems is suggested and makes it possible to determine gems more fast and accurately.
