摘　　要：通过控制偏光显微镜的起偏镜旋转角度可以实现焦炭气孔壁平均最大反射率_(max)和平均双反射率bi的自动测定。经回归分析发现,_(max)和焦炭反应性CRI,以及反应后强度CSR之间存在显著的相关关系,相关系数r分别达到-0.926和0.949。_(max)和焦炭机械强度DI_(15)^(150)之间的相关性相对较弱,r为0.704。_(bi_和焦炭各强度指标之间没有发现明显的相关关系。The mean maximum reflectance R^-max and mean bireflectance bican be measured automatically by controlling the angle of polarizer of microscope. By means of regression analysis,significant the correlationships were found between R^-max and coke reactivity CRI,and coke strength after reaction CSR as well. The values of r were-0.926 and 0.949,respectively. The correlationship between R^-max and coke mechanical strength DI15^150 was weak obviously,the r of which was only 0.704. No obvious correlationship was found between R^-bi and any other coke property index.
