The determining factors of the rate ratio come from the joint contribution of the activation enthalpy and activation entropy. 活化熵对反应速率常数比值的贡献是不可忽略的.
The apparent active energy, active enthalpy and active free energy of relaxation process of WPC are smaller than control wood, and those of WMC are greater than control wood. WPC较木材的表观活化能降低，活化焓和活化自由能减小，而WMC表观活化能、活化焓、活化自由能增加。
The parameters of Andre's equation were modified and a new method used to estimate the viscosity of LGP at low temperature was developed by way of the combination of the activation enthalpies of viscous flow with those of glass transition. 并与玻璃化转变的活化焓结合起来，对由普通方法得到的安德烈方程的几个参数进行修正，从而发展了一种改进的预测液体发射药低温粘度的方法。
The great discrcpeney in activation enthalpies might indic-cate that the differences were in the response to change and tension strength of the substrates and active center of catalases when active complexes were formed through soil catalases. 活化焓差别较大,说明各土壤过氧化氢酶形成活化络合物时,底物与酶活性中心在应变和扭曲强度上的差异。
