    首先给出坐标本征态的Fock表象,然后推导出真空投影算符0〉〈0的正规乘积形式,最后利用IWOP技术导出了单模压缩算符S=∫∞-∞（dx/u（1/2）~2│x/μ〈x│=e-（a＋2/2）thλe（a＋a＋1/2）Insechλe（a2/2）thλ,并分析了其压缩特性。

    In this paper, the Fock representation of the coordinate eigenstate is gived. The normal ordering form of the vacuum projection operator is derived. The single-mode squeezing operator is derived using IWOP technique, and the compression properties are analysed.
