| 摘 要： | 采用伪谱展开和保结构算法数值求解了强激光场中的一维含时Schroedinger方程，本征谣中的分立谱和连续谱分别应用辛-打靶法与保Wronskian行列式的辛-算法得到。最后方法被用于计算强激光场中原子的电离，得到的结果与物理理论分析一致。

| Abstract: | In this paper one-dimensional time-dependent Schroedinger equation in intense laser field is numerically solved based on the pseudo -spectrum expansion and structure- preserving algorithm, and the Symplectic Scheme- shooting Method and the Wronskian- preserving Algorithm are adopted to solve the eigenvalues and eigenfunctions of the discrete spectrum and continuum spectrum included in one - dimensional time - independent Schroedinger equation. Finally the process is used to compute the ionization of the atom in intense laser field, and the result is identical to the physical meaning. |
