| 摘 要： | 构造了有限维希尔伯特空间非简谐振子广义相干态，利用了Barnett和Pegg提出的测量相位算符，讨论了该量子态的测量相位算符的压缩效应，给出了压缩条件与参数之间的关系，理论计算表明该量子态存在测量相位算符的压缩效应。

| Abstract: | Generalized coherent states in a finite-dimensional Hilbert space is constructed. Its squeezing properties are discussed via the measured phase operators introduced by Barnett and Pegg. The conditions of squeezing are found. Theoretical calculation shows that it presents squeezing effect. |
