标准摘要
[中文适用范围]： 本文件建立了一种基于等转化率原理的化学反应和相变模型无关的等转化率动力学分析方法。等转化率原理基于以下假设：在给定转化率下，反应速率仅取决于温度，即与扫描速率无关。本文件建立了一种测定反应或相变的活化能随转化率变化的方法。该方法适用于通过差示扫描量热法（DSC）或热重法（TG）进行的动态和等温温度程序测量。它也可适用于其他能够测定转化率曲线的测量技术。该方法适用于预测反应和相变的动力学行为，即使在实验无法触及的温度区域。该方法不适用于聚合物的玻璃态。 [外文原描述]： This document establishes a model-free approach for the isoconversional kinetic analysis of chemical reactions and phase transitions. The isoconversional principle is based on the assumption that the reaction rate at a given conversion depends solely on the temperature, i.e. is independent on the scan rate. This document establishes a method for the determination of the activation energy as a function of the conversion of the reaction or transition. The method is applicable to dynamic and isothermal temperature program measurements done by differential scanning calorimetry (DSC) or thermogravimetry (TG). It can be applicable to other measurement techniques, too, that enable the determination of conversion curves. The method is applicable to the prediction of the kinetic behaviour of reactions and transitions even in temperature regions that are not experimentally accessible. The method is not applicable in the glassy state of polymers.
