摘　　要：研究了一初始处于基态的二能级原子与迭加态光场相互耦合的ｋ光子Ｊａｙｎｅｓ－Ｃｕｍｍｉｎｇｓ模型中场的振幅Ｎ次方压缩特性。结果表明，当迭加态的光子数ｎ≥ｋ时，场不仅可存在振幅ｎ次方压缩，而且当ｎ为偶数时还存在振幅的ｎ／２次方压缩。The properties of the amplitude- Nth powered squeezing of the field in the k-photonJaynes-Cummings medel of an atom initially in the ground state coupling with the superpositionstates are investigated in this paper. The results show that,under the condition of the photon numbern≥k of the suporposition states , the field exhibit not only the nth powered squeezing of theamplitude but aiso the(n/2)th powered squeezing of the amplitude when k is even。
