摘　　要：烟煤奥亚膨胀度测定实验是直接测定烟煤粘结性的一种重要方法。它不仅能反映胶质体的量还能反映胶质体的质。是研究煤质、指导煤炭开发、生产、加工利用的重要方法。该方法可获得煤的最大膨胀度b值,最大收缩度a值,软化温度T_(1),始膨胀温度T_(2),固化温度T_(3)。《烟煤奥亚膨胀度测定实验》属于煤化工方向专业基础实验,重点是让学生掌握《煤化学》中学到的理论知识,让理论进一步升华为实践动手能力。The experiment of measuring the expansion degree of bituminous coal is an important method to directly determine the caking property of bituminous coal.It can reflect not only the quantity of colloid but also the quality of colloid.It is an important method to study coal quality and guide coal development,production,processing and utilization.By this method,the maximum expansion degree b,maximum shrinkage a,softening temperature T_(1),initial expansion temperature T_(2) and curing temperature T_(3) of coal can be obtained.The experiment of measuring the expansion degree of bituminous coal belongs to the basic experiment of Coal Chemical Industry,which focuses on making students master the theoretical knowledge learned in Coal Chemistry and further sublimating the theory into practical ability.
