摘　　要：讨论了ｑ形变玻色算符的广义逆算符作用于ｑ－相干态所得到的两类量子态的数学及量子统计性质。结果表明，ｑ－相干态的光子激发态不存在压缩但呈现反聚束效应，而ｑ－相干态的光子湮灭态却存在压缩但不呈现反聚束效应。The mathematical and Quantum properties of two kinds of quantum states generated by repeated application of the q analogue  boson inverse operators on the q coherent  state are discussed. It is shown that the excited states of q coherent  state show antibunching effect but no squeezing. However for the photon depleted states of q coherent  state there is squeezing but no antibunching for all finite q values. 
