摘要
用显微镜描绘技术在绘图纸上绘出线条清晰，反差很大的岩石薄片手绘图像，再将手绘图像通过电视摄像机（ＣＣＤ）输入到计算机自动图像系统中处理，可以取得组成岩石主要矿物的密度分布、粒度、形状及空间分布模式，揭示岩石特征，为岩石学定量研究提供参数。
With the help of the technique of microscope description, the manual image of rock thin sections with clear lines and large contrast can be delineated on the drawing paper. After the image is processed in the auto image system by feeding the image into CCD, the density distribution, grain size, shape, and spatial distribution of main minerals in a rock are obtained, which can be used to reveal the characteristics of the rocks and to supply parameters for the quantitative study in petrology.
