摘　　要：利用多模辐射场广义非线性不等幂次差压缩的一般理论，研究了任意两态叠加多模泛函叠加态光场的广义电场分量的非线性不等幂次差压缩特性。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）当前q模压缩次数和与后q模压缩次数和都为偶数时，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电场分量的非线性差压缩效应；2）当前q模压缩次数和与后q模压缩次数和都为奇数时，在一定条件下，任意两态叠加多模泛函叠加态光场中，广义电场分量呈现出周期性变化的广义非线性Nj次方差压缩效应；3）没有发现“奇怪压缩现象”。The general theory of generalized nonlinear unequal-power difference-squeezing of Multimode Radiation Light-Field is utilized to study the properties of unequal-power difference-squeezing of generalized eiectric-field component of the arbitrary two-states superposition multimode functional superposition state light-field.The general theory result is obtained, the properties of unequal-power difference-squeezing in two special two-states superposition multimode functional superposition state light-field are discussed. It is shown that 1）When sum of squeezing power on front q mode and sum of squeezing power on latter q mode is a even-numbers, not appears as the properties of generalized nonlinear unequal-power difference-squeezing of generalized electric-field component in the first kind of two-states superposition multimode functional superposition state light-field and imaginary number coherent two-states superposition multimode functional superposition state light-field; 2） When sum of squeezing power on front q mode and sum of squeezing power on latter q mode is a odd-numbers, generalized electric-field component of the arbitrary two-states superposition multimode functional superposition state light-field can display the effect of generalized nonlinear Nj-power difference-squeezing which changes periodically and alternatively under a series of fixed conditions; 3） ＂The phenomenon of strange squeezing＂ has not been found.
