用热分析法研究聚合热降解或固体热分解反应动力学￣［１］，可用微分法和积分法进行数据处理。前者直接从热谱图上读取值，可能引入大的误差，故更多的是采用积分法。而积分动力学方程中有一个不可积项∫ｅｘｐ（—Ｅ／ＲＴ）ｄ＿Ｔ，为了求解，许多作者对该项作了近似处理。本文在以前近似式的基础上，提出了一个新的非等温动力学方程，并对各近似式在不同ｘ（ｘ＝Ｅ／ＲＴ）下与相应的∫ｅｘｎ（－Ｅ／ＲＴ）ｄ＿Ｔ积分值比较，得出各个近似式的误差范围，并以误差σ对ｘ作图。从结果可见，本文提出的方程在使用范围和精度上都有进一步的提高。
Thermal analysis of thermal degradation of polymer or solid thermal decomposition reaction kinetics ~ [1], the differential method and the integration method for data processing. The former directly from the thermogram to read the value may lead to large errors, so more is the use of integral method. However, there is an incoherent item ∫exp (-E / RT) d_T in the integral kinetic equation, and many authors have approximated this for solution. Based on the previous approximation, a new non-isothermal kinetic equation is proposed and the corresponding integrals of the approximations with the corresponding ∫exn (-E / RT) d_T under different x (x = E / RT) Compare, draw the error range of each approximation, and the error σ plotted on x. As can be seen from the results, the equation proposed in this paper has been further improved in terms of the range of use and accuracy.
