摘　　要：在FOCK空间建立了一类新的非线性相干态.采用数值计算方法,对其压缩和反聚束等量子统计特性进行了研究.这些结果表明,在|α|范围内,这种新型的奇偶相干态在X2方向出现了压缩效应和反聚束效应.In the paper,a new kind of even and odd nonlinear coherent states is constructed in the Fock space. Using numerical method,their quantum statistical properties such as amplitude-squeezing and anti-bunching are investigated. The results show that in the range of ｜α｜,amplitude-squeezing effect and anti-bunching effect appear in the direction X2 in the new kind of even and odd coherent states.

关 键 词：非线性奇、偶相干态 压缩效应 反聚束
