摘　　要：本文讨论了以往强激光诱导自电离理论所忽略的二阶以上的高阶离化效应,得到了自电离谱的解析表达式,详细研究了高阶离化的影响。结果表明,当激光场足够强时,高阶离化使自电离谱和自电离态的缀饰态产生显著变化。High-order ionization processes, which have been ignored previously in the studies of intense laser-field induced autoionization, are discussed. After obtaining the analytic solution for autoionization spectrum, we investigate in detail the effects of high-order processes. These processes, as shown in the present paper, will affect drastically the autoionization spectrum and the dreesed states of the autoionization state.
