The repulsion between the electrons makes it energetically more favorable for the electrons to avoid each other . 电子间的排斥有力地促使电子反应回避。
2.
The catalyzing of the highly performanced catalysts made reaction a quasi four electrons process . the catalyst was applied in the electrochemical oxygen generator and the effect was very good 通过活性炭和la _ ( 1 - x ) sr _ xmno _ 3联合催化，完成氧气还原的二电子反应历程，实现了氧气的四电子转移；高性能的催化，使电极具有氧还原的类四电子反应历程。
