摘　　要：本文研究了光子消灭算符α的任κ次幂算符α~κ的正交归一本征态的高阶压缩特性。研究结果表明:光子消灭算符α的偶数次幂α~κ的正交归一本征态一定不存在N<κ,但N≠κ/2的第2N阶压缩,只可能存在第κ阶压缩和N≥κ的第2N阶压缩;光子消灭算符α的奇数次幂α~κ的正交归一本征态一定不存在N<κ的第2N阶压缩,只可能存在N≥κ的第2N阶压缩。In this paper, the high-order squeezing characteristic of orthonormalization eigenstates of a fourth power of photon annihiation operator were studied. It is pointed that 2N(N<κ, N=κ/2) order squeezing can not exist when κ is even but κ-order squeezing and 2N-order squeezing may exist; the 2N(N<κ) order squeezing can not exist when κ is odd, but the 2N(N>κ)-order squeezing may exist..
