摘　　要：对一种多模叠加态光场Ψ(2)〉q的不等幂次Nj次方H压缩特性进行了详细的研究.结果发现,当各模的压缩幂次数之和为奇数时,多模叠加态光场Ψ(2)〉q在一定条件下呈现出周期性变化的不等幂次Nj次方H压缩效应.The properties of unequal-power Nj-th power H-squeezing of a kind of multimode superposition state light field Ψ（2）〉q with the superposition of two states are studied in detail.It is found that,when the sum of the squeezing orders of each mode is even number,the multimode superposition state light field ｜Ψ^（2）〉q is always in Nj minimum uncertainty state;when the sum of the squeezing orders of each mode is odd number,under some conditions the multimode superposition state light field ｜Ψ^（2）〉q can also present Nj-th power H-squeezing that changes periodically.
