摘　　要：针对有限维Ｆｏｃｋ空间谐振子的奇偶相干态的高阶压缩特性。具体研究了在这种奇偶相干态中正交算符的任意阶压缩性质。研究结果表明，在特定条件下，正交算符在偶相干态中有２Ｎ阶压缩。In this paper, we investigate the higher order squeezing properties of even and odd coherent states of a harmonic oscillator in a finite dimensional Fock space. In particular, the arbitrary higher order squeezing of the quadrature operators in these states is studied. It is shown that in definite conditions, the quadrature operators in even coherent states have 2Nth order squeezing , and the different order squeezing exhibit their maximum squeezing under the same conditions.
