1·A method of calculating force field of polyatomic molecule with model potential function is presented.

本文提出了一套用模型势函计算多原子分子力场的方法。

2·This model can be applied to the polyatomic molecule in that there is a weakly bond, and after the reaction the molecule can be split into two parts.

这个模型适用于参加反应的多原子分子中有一个键较弱，且反应结束后可分为两部分的多原子分子。
