在G2（B3LYP／MP2／CC）水平上对NCO+O反应体系进行了ab initio理论计算。得到了反应势能面上的各物种的优化构型参数和能量，并对可能的反应通道进行了计算和分析。

A detailed analysis of the experimental results implied that the attractive forces play a main role in the collisional quenching processes of NCO by the quenchers studied in this work, and for some quenchers, the quenching of NCO is probably controlled by the entrance-channel and might be ascribed to the contribution of chemical reactions.

这一加成过程是一个入口势能面属于纯吸引型的无垒过程，故是NCO+O反应的主要通道。二是O原子攻击NCO分子的O原子得到中间物tran-NCOO，再通过C-O键的断裂生成产物CN+OO。该产物通道由于是吸热的，故很难发生。

The secondary ion yield has a maximum value when the projectile kinetic energy is...

分析表明，这是势能沉积作用与线性级联碰撞过程协同作用的结果。

Of simplicity, the ELJP model predicts the VLE for HCFC/HFC as well as other weak polar binary systems accurately. However, its parameters are determined by fitting vapor pressure and liquid density data of the pure substance over a temperature range of interest, and are, therefore, temperature dependent.

其缺点是分子的势能模型未能直接反映分子的极性，其参数须随温度而变，且这些参数又是由纯物质的一系列饱和蒸汽压和液相密度的实验数据回归得到，故存在一定局限性。
