摘要: 采用辛算法和R-K法计算了N2双原子系统的经典轨迹。结果表明,辛算法保持系统的辛结构和固有性质不变,与实验和理论一致;R-K法则与实验和理论不符。

Abstract: Classical trajectories of diatomic system N2 are calculated by means of both Symplectic and R-K algorithms.It is shown that Symplectic algorithm keeps Symplectic structure of the system and its intrinsic qualities unchanged and consistent with the theory and experiment. R-K approach is not the case.

Key words: Diatomic system, Classical trajectory approach, Symplectic algorithm
