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 同時也說明在研究多原子參與的化學(xué)反應(yīng)中, svrt模型是一種實際可行的方法,值得應(yīng)用到更一般的多原子分子反應(yīng)體系中去。
