the energy that an atomic system must acquire before a process (such as an emission or reaction) can occur
The binary gasless SHS processes with large overall activation energies were studied. 对具有大活化能的二元无气SHS过程进行了研究。
Moreover,the reaction path,activation energies and equilibrium constance during the tautomerized reaction involving hydrazone form and azo form are obtained. 此外,还计算了醌腙式和偶氮式结构在互变过程中,反应路径、正逆反应活化能以及化学平衡常数。
The activation energies of the reaction in the absence of catalyst and in thepresence of zinc chloride were 51.3 and 8.3kJ/mol respectively. 求得无催化剂及以氯化锌作催化剂时的反应活化能
The apparent activation energies for propagation were 54.4, 42.9 and 24.9 kJ/mol when DPE/n-BuLi were 1.0, 5.0 and 10.0, respectively. 当 DPE/n-BuLi分别为 1.
The corresponding activation energies Ezn and Epb are 16.39 and 34.10 kcal when the pressure is 13.3Pa and the melt is not stirred. 在熔体无搅拌
