摘　　要：利用BarbettS M和PeggD .T提出的测量相位算符 ,研究有限维偶奇相干态中测量相位压缩性质。着重讨论了Hilbert维数s对偶奇相干态中测量相位压缩的影响。结果表明 :在有限维偶奇相干态中 ,cosmφ存在CS类压缩 ,压缩的深度与Hibert维数s、|α| 2 及δ有关。The properties of the phase squeezing in even and odd coherent states of a finite-dimensional Hibert space have been studied via the measured phase operators introduced by Barnett S M and Pegg D T.The influences of dimensional size of Hilbert space on squeezing of measured phase operarors have been discussed emphatically.It is shown that the cos mφ has squeezing in the CS type in even coherent states,and the degree of squeezing is relevant to s,|α|2 and δ.
