摘　　要：以煤的基氏流动度实验作为研究胶质体性质的出发点,提出以加权平均流动度lgF_(wa)和最大流动度lgF_m分别代表整个阶段胶质体所体现的平均质量和最佳质量,并提出以软固温度区间T_r-T_s表征胶质体数量.在此基础上,以因子分析为综合评价胶质体性质的模型,建立一个全面表征胶质体性质的新指标——流动指数F,发现流动指数F较lgF_m与煤工艺性质有更密切的联系,具有更好的加和性,预测焦炭质量更准确,表明流动指数F作为黏结性指标可以全面反映胶质体的性质.Based on Gieseler fluidity test of coal as a starting point to research the fluidity property of coal, weighted average fluidity lgFwa and maximum fluidity lgFm are put forward respectively to represent the average and the best quality of gel in the whole stages , and the softsolid temperature range Tr-Ts is proposed as a parameter to reflect the amount of gel. Beside, a model of comprehensively evaluating the property of gel is proposed by factor analysis, as a re- suit, a new fluidity index F is reported. The relationships between index F and the properties of coal have better regularity than that of lgFm. Index F is verified to be a comprehensive reflection of the fluidity property for coal.
