摘　　要：本文利用玻色子湮灭算符构造了含时单、双模玻色系统的非厄密不变量。证明了广义含时相干态为非厄密不变量的本征态，讨论了这些态的压缩效应并推广了广义含时相干态概念。The non hermitian invariants of time dependent one or two mode Boson system are constructed by using Boson annihilation operators. The results show that the time dependent generalized coherent states are the eigenstates of these non hermitian invariants.The squeezing effect of these states is discussed and the concept of time dependent generalized coherent state is extended.
