本文提出了一种直接获得单模和双模压缩算符正规序形式的新方法。这种方法是基于“有序产品内的集成”技术。算子表达式推导出使用相干态表示以及坐标和动量表示。该方法非常简单，并且该方法具有直观的基础，使得压缩性质在一开始就显现出来。
A new method for directly obtaining the normally ordered form of single-and two-mode squeeze operators is presented. This method is based on the technique of ‘‘integration within an ordered product.’’The operator expressions are derived using the coherent-state representation as well as the coordinate and the momentum representations. The method is very simple, and the approach has an intuitive basis that makes the squeezing property manifest at the outset.
