摘　　要：目的研究一种两态叠加多模叠加态光场|Ψ(ab)〉q的奇次幂Y压缩特性。方法利用多模压缩态理论计算,分析,归纳,总结。结果得到多模叠加态光场|Ψ(ab)〉q的奇次幂Y压缩特性。结论当压缩幂次数Nj为奇数时,态|Ψ(ab)〉q在一定条件下总可呈现出奇次幂Y压缩效应。Aim The properties of even-power Y-squeezing in the multimode superposition state light field ｜ψ^（ab）〉q with the superposition of distinct two quantum states are studied in detail. Methods Account analytical induction and summarization by utilizing the theory of multimode squeezed states. Results The properties of even-power Y-squeezing is found in the multimode superposition state light field ｜ψ^（ab）〉q. Conclusion The squeezed power number Ni is an even number, under some certain conditions the state I ｜ψ^（ab）〉q can display the effects of even-power Y-squeezing.
