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次方Y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-Y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次方Y压缩效应。By using the theory of multimode squeezed state,the property of generalized nonlinear equal-order N-th power Y-squeezing in the multimode superposition state light field ｜Ψ^((2))〉_q with the superposition of arbitrary two quantum states is studied.It is evinced that the state ｜Ψ^((2))〉_q separately stayed equal-order N-Y minimum uncertainty state、present the effect of 'half coherent state'、the first quadrature component or the second quadrature component present the properties of N-th power Y-squeezing in different conditions.
