摘要
The purpose of this work was to utilize the Equivalent Point Method (EPM) for kinetic parameter estimation from dynamic thermal treatments. An assumption which was fundamental to the EPM, however, when found invalid led to the development of an alternative approach, the method of Paired Equivalent Isothermal Exposures (PEIE). The method provided conceptual simplicity and ease-of-use as well as improved accuracy and reproducibility. The fundamental assumption of the EPM was tested on a mathematical basis, and demonstrated with example calculations. Development of the PEIE method was explained and described with procedural steps. Sample calculations described implementation details of PEIE. The method successfully estimated Arrhenius kinetic parameters from realistic, arbitrary, dynamic thermal treatments.
