摘要

本文指出,由于忽略了牛顿冷却定律以来已知的热惯量的影响,用铸态差热分析曲线的简单分割来计算活化能的传统方法是错误的。这种误差交织在使用热测量的所有方法中。当使用缺少的项时,方法派生将得到升级。

Piloyan Method to Determine the Activation Energy from DTA is Defectivein Addition to other Methods which do not take into Account the ThermalInertia
The paper displays that the traditional method of kinetic evaluation of activation energies by simple portioning of the as-cast DTA curves is erroneous because is missing the impact of thermal inertia which is known since the Newton cooling law. This error is interwoven into all methods using thermal measurements. The method derivation is upgraded when using the missing terms.
