摘要/Abstract

摘要： 对于有特征热效应发生的化学反应,本文根据合理的动力学模型提出了二元线性回归解析DTA曲线,求取动力学参数的方法。该法的特点在于仅通过一次DTA实验及一次回归即得到多个动力学参数。结合实例详细说明了截取DTA数据的三次样条插值函数法及D-M分布函数法,并指出这两种计算方式求出的基本数据按二元线性回归法得到结果的一致性,可做为所求动力学参数正确与否的判据。

Abstract: In this paper, a method of quantitatively analyzing DTA curves by two de-mension linear correlation, with which the kinetic parameters are obtained, is put forward according to the reasonable, kinetic model for the chemical reaction with characteristic thermal effect. The characteristics of this method is that some kinetic parameters are obtained by once experiment of DTAand once calculation only.Two kinds of methods of obtaining the data of DTAare illustrated in detail by some examples, and it is put forward that identity of the results obtained by two demension linear correlation with the data from two kinds of calculated methods is used as the criterion whether the kinetic parameters are correct or not.The results are compared with that of other researchers methods.
