越过马鞍点和前因子所需的能量决定该过程的速度。
The rate of a process is based upon the energy barrier required to cross the corresponding saddle point, and a harmonic prefactor.
随着转化率的增加，活化能和指前因子也随着增加。
With the increasing of conversion, activation energies and pre-exponential factors were also increased.
分析了其绝热分解的过程，计算了表观活化能、 指前因子和反应热等参数。
Thermal decomposition results were analyzed, and kinetics parameters such as apparent activation energy, pre-exponential factor and reaction heat were calculated.
结果表明：反应物的粒度对反应的速率常数、 反应级数、表观活化能和指前因子均有较大的影响；
The results show that there are obvious effects of the sizes on the rate constant, the reaction order and the activation energy;
