将辛算法推广到复辛空间 ,指出了辛算法保定态 Schrodinger方程的 Wronskian守恒。将辛算法应用于强场一维模型的计算中 ,并与 Runge-Kutta法作了比较。结果显示 ,辛算法保持定态Schrodinger方程的 Wronskian守恒 ,适合于在充分远空间上计算线性无关解 ,是计算强激光场一维模型的合理的数值方法 The symplectic algorithm is generalized to complex symplectic spaces, and the Wronskian conservation of the Poisson Schrodinger equation is pointed out. The symplectic algorithm is applied to the calculation of one-dimensional model of strong field and compared with Runge-Kutta method. The results show that the symplectic algorithm preserves the Wronskian conservation of the stationary Schrodinger equation and is suitable for calculating the linearly independent solution over a sufficiently far space, which is a reasonable numerical method for calculating the one-dimensional model of a strong laser field
