準確地測定矿物折光率是鑑定透明礦物的最重要最簡便的方法。拉森與貝滿所著透明矿物显微鑑定(1934)一書中,即將各種礦物依光性和折光率大小的順序排列。测定了矿物的折光率,即可由此檢索礦物的種類或名稱。关於矿物折光率的測定法一般光性礦物學著作中,如溫切爾的光性礦物學綱要(1937),羅傑士與克爾的光性矿物學(1942),瓦魯斯仇母的光性結晶學(1951)等,雖有論及,可是對测定方法和理論根據,皆語焉不
Accurately determining the refractive index of minerals is the most important and easiest way to identify transparent minerals. Larson and Pui Man by the transparent mineral microscopic identification (1934) a book, the various minerals according to the order of light and refractive index. Determination of the refractive index of minerals, which can be retrieved from the type of mineral or name. Determination of mineral refractive index General photothermographic writings, such as Winchell’s light mineralogy outline (1937), Rogers and Kerr of light mineralogy (1942), the light of the mother of Varus Sexual Crystallography (1951), etc., although discussed, but on the measurement methods and theoretical basis, are not Yan
