指前因子
pre-exponential factor
- 最后用速率常数法计算了两种硝铵炸药的活化能E和指前因子A。
Finally, the activation energy E and frequency factor A were calculated by the velocity constant method. - 通过对实验数据的回归，求取了反应动力学速率常数，反应活化能和反应的指前因子。
Rate constants, frequent factors and activation energies parameters were estimated according to the experimental data. - 随着反应物粒径的减小，反应的表观活化能和指前因子减小而速率常数和反应级数增大；
The results show that: there are obvious effects of the reactant particle diameter on rate constants, reaction order, apparent activation energy and pre-exponential factor in the reactions;
