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。Classical trajectories of diatomic system N 2 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.
