1　引言　　原子在强激光场中的稳定现象 1984年曾首次被理论预言和描述 [1 ,2 ] ,实验验证则仅仅是最近的事 [3 ,4]。原子稳定思想并不对应于原子电离速率随激光场强度增加这一简单直觉。根据定义 ,稳定意即依赖于强度 I或场强ε,从某些临界值 Ic或εc开始 ,电离速率Γ或总电 1 INTRODUCTION The stabilization of atoms in a strong laser field was first predicted and described by theory in 1984 [1,2], and experimental verification is only the most recent one [3, 4]. The idea of ​​atomic stability does not correspond to the simple intuition that atomic ionization rate increases with laser field intensity. By definition, the stability is either dependent on the intensity I or the field strength ε, starting from some of the critical values ​​Ic or εc, the ionization rate Γ or the total electricity
