长寿命轨线形成的模式识别研究

设计了6个参数来定量表征共线势能面的几何特征，并寻48个具有不同几何特征的LEPS型势能面，在以7个参数表征的不同的动态条件下应用Venus94程序进行准经典轨线(QCT)计算。随后，应用模式识别研究了势能面的特征及动态因素对长寿命轨线形成的影响，初步证实了若干知的并发现了若干新的影响长寿命轨线形成的主要影响因素并据此建了长寿命轨线形成的定性预测模型。

Pattern reacgnition study on the fromation of long -lived trajectory

48potential energy surfaces (PES) based on LEPS molde have been designed, which are parameterized with 6 geometry characters and 240 samples are calculated by QCT method (1 000 trajectories in each sample), according to the different reaction conditions, which had been parameterized with 7 dynamical characters. Then, the methodolgy of pattern recognition is used to analyze the relationship between the observables and the PESs and the reaction conditions. After this analysis, some known rules and new informations about the formation of long -lived trajectories are obtained. By using the discriminate equation obtained through pattern recognition, the behavior of unknown samples can be predicted.
