研究化学或物理过程中发生的反应机理是化学家、物理学家和化学家感兴趣的课题。本文评述了两种研究者感兴趣的情况，这些研究者通常借助于反应理论[1-5]来分析非等温数据。[6-10]第一个是指当等温和非等温时间的含义混合时引入的误差，第二个是我提出了一种分析非等温数据的通用方法，避免了对特定反应模型和反应初始温度T0的考虑。我的第一个观察是关于一些参考文献中从等温和非等温过程推导出的数学方程的模糊混合。[11]虽然反应速率模型的转化动力学基本方程表示为反应或转化分数的分数范围相对于时间t的导数，但显然它是一个函数（T，t），T是温度。
The study of the reaction mechanisms occurring during a chemical or physical process is a subject of interest for chemists, physicists, and metallurgists. In this article, I comment on two situaions of interest for the researchers who usually resort to the reaction theory [1–5] to analyze nonisothermal data.[6–10] The first refers to the error introduced when the meaning of isothermal and nonisothermal times are mixed, and in the second, I propose a generic way to analyze nonisothermal data, obviating the considerations regarding specific reaction models and the initial temperature of reactin, T0.My first observation concerns the ambiguous mixture of mathematical equations deduced from isothermal and nonisothermal processes in some references.[11] Although the basic equation for the kinetic of transformation from reaction rate models is presented as a derivative with respect to time t of the fractional extent of the reaction or transformed fraction, it is obvious that is a function (T, t), T being the temperature.
