摘　　要：利用煤焦显微分析系统测定了不同温度热解兰炭、纯工业兰炭及其所用原煤的反射率分布,并进行了兰炭掺煤实验。结果表明,通过镜质组随机反射率分布可辨别兰炭中掺混煤粉情况。通过测定兰炭的镜质组反射率分布区间可以判断兰炭的热解程度均匀性,分布区间越大,热解程度越不均匀。The reflectance distribution of pyrolysis char and industrial char at different temperatures and the raw coal used were measured by coal char microscopic analysis system. The results showed that it can be identified whether pulverized coal is mixed in the char through the distribution of the random reflectance of the vitrinite. The uniformity of pyrolysis degree of char can be judged by measuring the vitrinite reflectance distribution area of char. The larger the distribution interval, the more uneven the degree of pyrolysis.
