And it also shows some microscope dynamics mechanism of the system . the present results also demonstrate that the svrt model for atom - polyatom reaction provides a practical and accurate approach for studying chemical reactions involving polyatomic molecule 同时也说明在研究多原子参与的化学反应中， svrt模型是一种实际可行的方法，值得应用到更一般的多原子分子反应体系中去。
