经典哈密顿力学的辛算法

The Symplectic Method of The Classical Hamilton Mechanics

辛算法具有长时间的稳定性和跟踪能力,所以,运用辛算法求解哈密顿系统,尤其在长时间、步数多的计算中和保持系统整体结构上较其他非辛算法显示出明显的优越性。本文考虑辛算法的优点,论述了辛算法在强场物理、非线性物理、天体物理中的应用。

Symplectic method have stability of a long period and tracking capability.Therefore,we solves the Hamilton system by using the Symplectic algorithm,especially in the long time,step many computations and neutral maintain overall construction of the system,than the other non-Symplectic algorithm demonstrate superiority of the obvious.This article considered that the merit of the Symplectic algorithm,elaborated that application of the Symplectic algorithm in the strong field physics,nonlinear physical and the heavenly body physics.
