, which frequently occurs in non-isothermal thermal analysis, are presented. A series of the approximations for the temperature
integral with different complexity and accuracy are proposed from the procedure. For commonly used values of m in kinetic analysis, the deviation of most approximations from the numerical values of the integral is within 0.7%, except
the first approximation (within 4.0%). Since they are simple in calculation and hold high accuracy, the approximations are
recommended to use in the evaluation of kinetic parameters from non-isothermal kinetic analysis.
