摘　　要：根据化学反应动力学中的反应速度与温度关系的阿累尼乌斯(Arrhenius)经验公式,巧妙地将反应速度处理成温度变化率(上升率),测试出均匀粒度(0.22～0.45mm)无烟煤的挥发物着火的实验活化能。反应性值进一步通过数学手段处理成反应指数T_(15) 可反映煤中挥发物可燃质的量。In accordance with Arrhenius experience formula of relationship beivveen reaction velocity and temperature in the chemical reaction dynamics, technically reaction velocity was turned into temperature variation and experimental activation energy of igniting anthracite volatile particles (0. 22-0. 45mm)were measured. Reactivity value was further turned into reactivity index T15by mathematics method which can reflect quantity of combustible volatile in coal.
