The rate of a process is based upon the energy barrier required to cross the corresponding saddle point, and a harmonic prefactor.

越过马鞍点和前因子所需的能量决定该过程的速度。

Even Enrico Fermi apparently did not bother to read Hasenöhrl's papers properly before concluding wrongly that the discrepant 3/4 prefactor was due to the electron self-energy identified by Abraham.

就连恩里科·费米显然也没有下功夫好好拜读哈泽内尔的著作，才会错误地将3／4前因数的误差归咎于亚伯拉罕的电子自能。

And the prefactor is 96.3 3 when you want to get a result in kilojoules per mole.

当使用千焦每摩表示键能3,时前因子为96。
