| Abstract: | A new approximation for temperature integral is proposed by using pattern search method. The corresponding equation for the evaluation of kinetic parameters has also been obtained. The validity of the new temperature integral approximation has been tested with data from numerical calculating. And its deviation from the values calculated by numerical integrating was discussed. Compared with several published approximate formulae, this new one is much superior to all other approximations and is the most suitable solution for the evaluation of kinetic parameters from non-isothermal kinetic process. |
