摘要：
In terms of Lie theory the evolution of a time-dependent quantum system can be described by the dynamics of its generalized coherent state and its phase properties can be investigated by an Hermitian phase operator constructed from a generalized phase state we introduced. Two illustrative examples of SU(1,1) and SU(2) groups are presented. (C) 2002 Elsevier Science B.V. All rights reserved.
