摘　　要：本文由pegg-Barrentt的量子相位理论,研究了有限维空间谐振子相干态中的一对正交相位算符的压缩特性。According to pegg - Barnett' s quantum phase theory, the squeezing effects of quadrature phase operators in coherent states are studied. It is found than the coherent state exhibits higher- order squeezing effects.

关 键 词：相干态 正交相位算符 压缩效应 谐振子
