摘要 对Hamilton系统的辛Runge-Kutta-Nystrm方法的阶条件和阶特性作了进一步讨论,证明了单对角隐式辛Runge-Kutta-Nystrm方法的最高可能阶为6. In this paper, we investigate the order conditions and the order characterizations of symplectic Runge- Kutta-Nystrom (RKN) method on the Hamihonian system, make a study of the order of singly diagonally impletic symplectic RKN method and prove that the highest possible order is six.
