摘　　要：利用模式搜索法求取了一个新的温度积分近似式,给出了相应的估算动力学参数的方程。新的温度积分近似式根据数值计算结果得到,可靠性高。讨论了新的近似式计算值与温度积分数值积分结果的偏差。与其它近似式相比,新的温度积分近似式的表达式简单,精确度更高,非常适合非等温过程的动力学参数的计算。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.
