【摘要】 采集崆峒山白垩系斑马状泥岩样品,通过扫描电镜(SEM)结合Matlab软件处理技术和色差测量,得到了不同颜色泥岩样品的颗粒分布分形维数、表面灰度信息维数以及颜色参数值Lab。研究结果表明,赤灰与绿灰色为主的泥岩(取样剖面上部)的分形维数最小,灰绿色为主的泥岩(剖面中部)的分形维数最大;颜色越偏红、偏黄、偏亮,其分形维数越小;颜色量化值Lab与分形维数呈负相关。更多还原

【Abstract】 The Cretaceous zebra-like mudstone samples from Kongtong Mountain was collected. Using scanning electron microscope(SEM)with Matlab software processing and color-difference measurement, the partical distribution fractal dimension, the gray information dimension and Lab values of mudstone samples were obtained. The results show that the fractal dimension of red-gray and gray-green mudstone(the upper section of sampling section) is the smallest, and the gray-green mudstone(middle section) has the largest fractal dimension. The more reddish, yellowish, the smaller the fractal dimension. Quantified values Lab of the color are negatively correlated with the fractal dimension.更多还原
