【摘要】 本文对Ｋｅｒ偶奇相干态及其非经典性质进行了研究．结果表明：Ｋｅｒｒ偶相干态可呈现周期性的二阶压缩效应，Ｋｅｒｒ奇相干态则不存在这种压缩效应；但两者均可呈现周期性的振幅平方压缩效应，这与通常偶奇相干态的情形有所不同．更多还原

【Abstract】 In this paper,the Kerr even and odd coherent states and their nonclassical properties are investigated.It is shown that the normal squeezing can be only exhibited in Kerr even coherent state,and no squeezing will be observed in Kerr odd coherent state.It is also shown that the amplitude squared squeezing can be exhibited both for Kerr even and Kerr odd coherent states.This is different from the case of usual even and odd coherent states.更多还原
