改用均匀粒度粒子、标准燃烧曲线（型谱）试验测量一组低挥发澳大利亚煤的反应性．找出燃尽期间粒子收缩性与挥发分的函数关系，燃尽粒子表面积变化，发现５—８５％燃尽范围内活化能稳定。Ⅱ态燃烧的活化能随挥发分增加而减少，所测反应性值与其他报导高温载气燃烧同一煤的反应性值一致，但没介绍９００℃以上差示热重（ＤＴＧ）动力学值外推。
The average particle size was used and the standard combustion curve (type spectrum) test was used to measure the reactivity of a group of low-volatile Australian coal. Find the burnout period of the particle shrinkage and volatile as a function of the burnout particle surface area changes and found that the 5-85% burnout activation energy stability. The activation energy of Ⅱ state combustion decreases with the increase of volatile matter. The measured reactivity value is in agreement with that of other coal reported by high temperature carrier gas combustion, but no DTG kinetic value above 900 ℃ Push.
