用光学方法测定斜长石,主要就是测定随着成分和结构状态的变化而引起其光学常数和光性方位的变化。因此,准确测定折射率、消光角和光轴角,是斜长石鉴定中的主要光学数据。三轴旋转针台则是精确测定上述光学数据的最有效的测试手段。笔者和施加辛工程师合作,在当前有关测试仪器的基础上,研制出了三轴旋转针台(照片1、2)。笔者认为:三轴旋转针台改进和完善了费氏旋转台的操作、测试方法,使用各种
Optical determination of plagioclase, the main is to determine the composition and structure of the state changes caused by its optical constants and optical orientation changes. Therefore, the accurate determination of refractive index, extinction angle and optical axis angle is the main optical data in plagioclase identification. Three-axis rotary needle Taiwan is the most accurate measurement of these optical data the most effective means of testing. The author and the applied Xin engineers, based on the current test equipment on the basis of the development of a three-axis rotary needle Taiwan (photos 1,2). The author believes that: three-axis rotating needle table to improve and improve the Fei’s rotary table operation, test methods, using a variety of
