摘　　要：采用Brown-Ladner法计算出沥青的结构参数,通过中间相热转化试验获得转化的特征温度和所得生焦的光学显微组分来分析精制沥青的结构对中间相热转化过程的影响。The structural parameters of refined pitch were calculated by Brown - Ladner equation. The effect of the structure of refined pitch on the process of mesophase conversion was investigated using the characteristic temperature and optical micrographs of semicoke gained through mesophase thermal conversion.
