摘　　要：利用Barnett和Pegg提出的测量相位算符讨论了一种新的非线性相干态的压缩效应,得到了出现压缩的条件并给出了数值计算结果。The squeezing properties in a new kind of nonlinear coherent states are discussed via the measured phase operators introduced by Barnett and Pegg. The conditions of squeezing are found and the relations between the squeezing and the coherent parameters are shown by numerical calculation.
