	2	SYMPLECTIC RK METHODS AND SYMPLECTIC PRK METHODS WITH REAL EIGENVALUES显示文摘Properties of symplectic Runge-Kutta (RK) methods and symplectic partitioned Runge-Kutta (PRK) methods with real eigenvalues are discussed in this paper. It is shown that an s stage such method can't reach order more than s+1. Particularly, we prove that no symplectic RK method with real eigenvalues exists in stage s of order s+1 when s is even. But an example constructed by using the W-transformation shows that PRK method of this type does not necessarily meet this order barrier. Another useful way other than W-transformation to construct symplectic PRK method with real eigenvalues is then presented. Finally, a class of efficient symplectic methods is recommended.

	5	BOUNDEDNESS AND ASYMPTOTIC STABILITY OFMULTISTEP METHODS FOR GENERALIZED PANTOGRAPH EQUATIONS显示文摘In this paper, we deal with the boundedness and the asymptotic stability of linear and one-leg multistep methods for generalized pantograph equations of neutral type, which arise from some fields of engineering. Some criteria of the boundedness and the asymptotic stability for the methods are obtained.	Cheng-jianZhang GengSun	2004	Journal of Computational Mathematics2004，22，3：	0
