摘　　要：研究了偶奇q-相干态的振幅N次方（N≥2）压缩特性，发现偶奇q-相干态与通常的偶奇相干态有着不同的振幅高次方压缩特性，在一定条件下振幅奇次方压缩效应都可在这两种畸变态中出现。Properties of the amplitude Nth-power (N≥2) squeezing of even and odd q-coherentstates (q-CSs) are discussed. It is shown that the amplitude Nth-power squeeingproperties of even and odd q-CSs are very different from those of the usual even and oddCSs. It is found that the amplitude odd-power squeezing may appear for both even and oddq-CSs.
