从DTA曲线求反应类型为:固体(s_1)→固体(s_2)+气体(g)的反应级数和活化能,有多种方法.其中,有的方法从一个DTA曲线可得到反应级数,但必须做几个不同升温速率的DTA曲线才能得到活化能;有的方法虽然能从一个DTA曲线同时得到反应级数和活化能,但要求计算DTA曲线下的面积;有的方法从一个DTA曲线无需求算DTA曲线下的面积可以得到活化能,但不能同时得到反应级数.在以往的文献中,从一个DTA曲线同时得到上述反应的反应级数和活化能,而又无需计算DTA曲线下面积的方法还未见报导过.
From the DTA curve to find the reaction type: solid (s_1) → solid (s_2) + gas (g) of the reaction order and activation energy, there are a variety of ways in which there are some methods from a DTA curve available reaction series, However, it is necessary to do several DTA curves at different heating rates in order to obtain the activation energy. Although some methods can obtain the reaction order and the activation energy from one DTA curve at the same time, it is required to calculate the area under the DTA curve; Without calculating the area under the DTA curve, the activation energy can be obtained, but the reaction order can not be obtained at the same time.In previous literature, the reaction order and activation energy of the above reaction were obtained simultaneously from a DTA curve without calculating the DTA curve The method of area has not been reported yet.
