本文用尖点型突变统一模拟基元反应势能剖面的拓扑性质,用58个独立的基元反应系统分析了4种典型情况(可以通过坐标变换变成两种类型),得到的主要结果如下:(1)探讨了活化能概念;(2)发现反应O+CO→CO_2应属于反应类型Ⅳ,而不属于反应类型Ⅰ;(3)α1和α2之间可能存在某种特殊的相关。就有关结果进行了讨论。 In this paper, we use the sharp-point mutation to simulate the topological properties of potential energy profiles of the elementary reaction, and analyze four typical cases (which can be transformed into two types by coordinate transformation) using 58 independent elementary reaction systems. The main results are as follows: (1) discussed the concept of activation energy; (2) found that reaction O + CO → CO_2 should belong to reaction type Ⅳ, but not reaction type Ⅰ; (3) there may be some special correlation between α1 and α2. The results were discussed.
