摘要
用碰撞理论、活化能和过渡状态理论说明了三分子反应很少见的原因，并阐述了三分子反应的作用过程，列举了部分三分子反应，说明存在三分子反应。
Using the Theory of Collision and Activated-energy and Transition state illustrates the reason of seldom-seen of trimolecular reaction. And the paper expatiates on function process of trimolecular reaction and enumerates parts of trimolecular reaction and it proves the existing of trimolecular reaction.
