摘　　要：采用德国耐驰公司的TG209热重分析仪,针对在不同粒度、不同供氧浓度和不同升温速率的实验条件下,开展热重分析实验研究。通过对煤样氧化过程失重和失重速率曲线的分析,表明特征温度点可以从宏观上反映出煤样氧化微观过程中外界条件对反应过程的影响,并研究了不同实验条件对特征温度点和失重值的影响规律。The thermogravimetric analysis on the coal sample was conducted in the test conditions of different partical size , different oxygen density and heating rate by the TG209. By analysing the weightlessness and its rate curve of coal oxidation process ,it shows that the characteristic temperature can refleet the influence of external conditions on coal oxidation process from a macro point. The influential law of characteristic temperature and weightlessness value in different experimental conditions is studied.
