| 摘 要： | 中间相含量作为炭材料前驱体沥青的一项关键指标,在研究和制备中间相沥青时具有着重要的意义。图像处理法测定中间相含量在参考传统定量显微技术的基础上,结合计算机图像处理技术划分出偏光图像中的3个区域,有效地分辨出中间相和各向同性部分的灰度阈值,从而能较为便捷准确得出中间相含量。对比于选择性溶剂萃取法的结果,该法能更好地反映中间相的真实含量。

| Abstract: | The quantitative assessment of the me sophase content of pitches is one of the key indicators on studying and fabricat ing mesophase pitches.Reference to traditional quantitative optical techniques, a new image analysis technique was introduced to analyze the mesophase content, which was an image recognition and statistics computer program.According to th e new technique,polarization image was divided into three parts by gray level a nd the gray threshold was detected for distinguishing anisotropic and isot... |
