摘　　要：利用多模压缩态理论研究了一种非对称多模叠加态光场 |Ψ(ab)I 〉q的Nj次方H压缩特性 结果发现 :当各模压缩幂次数之和为偶数时 ,态 |Ψ(ab)I 〉q 的第一或第二正交分量可分别呈现出周期性变化的Nj 次方H压缩效应 。The properties of N j th power H squeezing in the first kind of asymmetrical multimode superposition state light field |Ψ (ab) I> q with the superposition of macroscopically distinct two quantum states are studied in detail.It is found that if the sum of squeezed power number N j of the all model is an even number, under some certain conditions the state |Ψ (ab) I> q can display the effects N j th power H squeezing that changes periodically, and post the foundation of producing degenerate squeezing
