The possibility of using the model free isothermal prediction procedures for complex processes was critical analyzed. Such procedures based by isoconversional method suggested by Friedman, and three incremental isoconversional methods have been suggested and verified for simulated data corresponding to two first order parallel-competing reactions and two first order consecutive reactions. It has been shown that in order to obtain a satisfactory prediction, these procedures must include the initial stage of determining the range of heating rates at which the thermoanalytical date necessary for the application of these procedures must be recorded, and to consider that the apparent activation parameters depend on both the conversion degree as well as the temperature for which the prediction is made.

对复杂过程使用无模型等温预测程序的可能性进行了批判性分析。这种程序基于弗里德曼提出的等转化方法，并针对对应于两个一级平行竞争反应和两个一级连续反应的模拟数据提出并验证了三种增量等转化方法。已经表明，为了获得令人满意的预测，这些程序必须包括确定加热速率范围的初始阶段，在该范围内必须记录应用这些程序所需的热分析数据，并考虑表观活化参数取决于转换程度以及预测的温度。
