摘　　要：利用显微图像采集软件,在计算机下进行粒度分析是一种新的尝试,可以改变传统的粒度分析在显微镜下工作易疲劳、操作繁杂等缺点,将薄片图像转移到计算机上,具有准确的标记已检测区域、明晰粒度数据、采集并保留测试图像资料等诸多优点。文章简述砂岩计算机下薄片粒度分析思路与测试方法,应用1/250000阿亚克库木湖幅的10个薄片,并将测试结果与已知数据进行了对比,粒度参数数据基本一致,认为此方法具有科学性和实用性。在计算机下进行粒度分析工作的方法,是结合科技发展的新思路。With complex operations, it is accepted that work on microscope is easy to cause fatigue. It is a new attempt to conduct grain analysis on computer through microscopic image acquisition softwares. Compared to traditional ways, it delivers the thin section images to computer, which makes it possible to mark the detected area accurately and clear the granule size data, furthermore, by this way researchers could reserve image data as reference for future, etc. In this paper, a brief description of ideas and testing methods about sand- stone grain size analysis on computer is added. Applying analysis on 10 thin sections from 1/250000 Ayakkum Lake Map Sheet, a comparison of testing results and known data is gained, which shows the grain size parame- ter are almost consistent, the method used has scientificity and utility. Doing grain size analysis by computer is a new thought that accompanies with the development of science and technologies.
