摘　　要：利用多模压缩态理论,研究了任意两态叠加多模叠加态光场|Ψ(2)〉q的广义非线性等幂次N次幂H压缩特性。结果表明,在不同的条件下,态|Ψ(2)〉q分别处于等幂次N-H最小测不准态、呈现"半相干态"效应,第一正交相位分量或第二正交相位分量可分别呈现出等幂次N次幂H压缩效应。并且说明了多模偶相干态光场、多模奇相干态光场、多模复共轭偶相干态光场、多模复共轭奇相干态光场等中N次幂H压缩都是笔者研究的任意两态叠加多模叠加态光场的等幂次N次幂H压缩效应的特殊情况。By using the theory of multimode squeezed state,the property of generalized nonlinear equal order N order H squeezing of the arbitrary twostate superposition mulitmode superposition state light field is studied firstly in detail.It is found,under different conditions,that the state is stayed in equal order NH minimum uncertainty state,and played in 'half coherent state' effect,and played in equal order N order H squeezing effect.Besides,it shows that the conclusions in the multimode even coherent state,mulitmode odd coherent state,mulitmode complex conjugation even coherent state,mulitmode complex conjugation odd coherent state and the like are some special circumstances which have been.
