光笔图象分析系统的问世,使岩矿分析人员从大量的统计工作及复杂的计算工作中得到解脱.同时也极大地提高了薄片粒度测定的效率与质量.为进一步扩大使用,使其为岩石结构学提供更多的信息,本文讨论了如下问题:仪器使用原理;测试中应注意的问题;线段百分比程序的使用;地质效果举例.

Since the establishment of light pen-image analysing system, the per-sonnel involved in rock and mineral analysis have been extricated from large amount of statistical and complex computation, and the efficiency and quality of the measurement of particle size have been greatly improved. In order to extend the range of application of the method, and to provide more data for petrofabric, the following problems a e discussed. Operational principles of the instrument; Noticeable problems during testing; Usage of the program of line-section percentage; Case study of the application.
