摘要
参照GB2293──80“煤沥青喹啉不溶物测定方法”，对煤焦油类物料和煤沥青炭化产物QI测定方法进行了适当改进，并与德国DIN51921──1985标准进行了比较。结果发现DIN5192──1985测试结果偏低，为两类炭素物料的QI含量快速准确测定提出了建议。
with reference to GB 2293──80, the method for determining QI in coal tarry materials and the earbonization products of coal pitch was modified properly and compared with DIN 51921──1985.The QI value determined by DIN 51921──1985 is lower.The suggestion on the rapid and accurate deterination of QI contents of two kind of carbonaccous materials is offered here.
