摘　　要：利用多模辐射场(简称MRLF)广义非线性不等幂次高次差压缩的一般理论,研究了由2q模相干态与其相反态线性叠加构成的两态叠加多模叠加态光场|ψ1(2)〉2q的二阶不等幂次高次差压缩(即Nj次幂x压缩)特性。结果发现:该多模叠加态光场在某些条件下呈现Nj次方x压缩效应。The general theory of generalized nonlinear unequal - power higher - power difference- squeezing of Multimode Radiation Light- Field （abbr. MRLF） is utilized to study the property of second- order unequal - power higher- power difference- squeezing（namely, Nj -th power X-squeezing） of two-state- superposition multimode superposition state light- field ｜Ψ1^（2） 〉2q, which is composed of 2q- modes coherent state and its contrary state according to the state superposition principle in quantum mechanics. It is found that under some certain and fixed conditions, the multimode superposition light- field mentioned above can display the effect of Nj - th power X - squeezing.
