摘　　要：构造了任意两态叠加多模泛函叠加态光场|ψ(f2)〉q,利用多模辐射场广义非线性等幂次高次差压缩的一般理论,研究了态|ψ(f2)〉q的广义磁场分量的非线性等幂次N次方差压缩特性.得到了一般理论结果,讨论了两种特殊两态叠加多模泛函叠加态光场的差压缩特性.结果表明:1)当qN为偶数时,第一类两态叠加多模泛函叠加态光场和虚相干两态叠加多模泛函叠加态光场都不出现广义磁场分量的非线性差压缩效应,也不处于N-j最小测不准态;2)当qN为奇数时,在一定条件下,任意两态叠加多模泛函叠加态光场中,广义磁场分量呈现出周期性变化的广义非线性N次方差压缩效应.The arbitrary two-states superposition multimode functional superposition state light-field ｜Ψf^（2）〉q is constructed. The general theory of generalized nonlinear equal-power higher-power difference-squeezing of Multimode Radiation Light-Field is utilized to study the properties of equal-power N-power difference-squeezing of generalized magnetic-field component of the state｜Ψf^（2）〉q.The general theory result is obtained, the properties of equal-power N-power difference-squeezing in two special two-states superposition multimode functional superposition state light-field is discussed. It is shown that：1）When qN is a even-numbers, not appears as the properties of generalized nonlinear equal-power difference-squeezing of generalized magnetic-field component and not appears as N-j minimum uncertainty state in first kind two-states superposition multimode functional superposition state light-field and imaginary number coherent two-states superposition multimode functional superposition state light-field;2） When qN is a odd-numbers, generalized magnetic-field component of the arbitrary two-states superposition multimode functional superposition state light-field can display the effect of generalized nonlinear N-power difference-squeezing which changes periodically and alternatively under a series of fixed conditions.
