应用两体扰动势，成功地构造了线性三原分子CO_2平衡态及通道反应的三原子 体系相互作用解析热。势函数不但定量地描述了CO_2平衡态的临界特性，而且势能 面正确的描述了O(~1D)+CO(X~1∑+)→CO_2→C(~3P)+O_2(X~3∑-_g)通道反应的性 质。理论分析与实验推测结果非常吻合。

Linear three-atom molecule CO_2 equilibrium state and interaction analytic potential of the pathway reaction of three-atom system have been successfully constructed by using the two-body perturbation potential. The potential function quantitatively describes the critical characters of CO_2 equilibrium state, and the potential energy surface correctly describes the characters of pathway in O(~1D) + COCX~1Σ~+ )→CO_2→C(~3P) + O_2(X_3Σ_g~- ) reaction. The theoretical analysis is in good agreement with the experimental results.
