将矿石制成光片在反光显微镜下进行研究,是地质研究工作的重要方法之一。因此,光片的质量对科研工作的进行有很大影响。本文介绍近年来在制备光片过程中的一些体会和有关技术方法,以供有关同志参考和交流经验。一、光片的种类和质量要求 1.普通光片一般大小为40×30×10立方毫米,根据具体情况和要求可略大或小。对其形状不严格限制,但必须有两个大平面。对光片的质量要求是:(1)按研究者的划线要求切割;(2)光洁度强,表
It is one of the important methods for the geological research to make the light made of ore under the reflective microscope. Therefore, the quality of light film has a great influence on the research work. This article describes some of the experience in the process of preparation of light films in recent years and related technical methods for the comrades to reference and exchange of experience. First, the type of light film and quality requirements 1 ordinary light film size is 40 × 30 × 10 cubic mm, according to the specific circumstances and requirements can be slightly larger or smaller. Its shape is not strictly limited, but there must be two large planes. Light quality requirements are: (1) according to the researchers crossed the cutting requirements; (2) good finish, the table
