摘　　要：构造了真空场注入三态叠加多模泛函叠加光场态|ψ0(IR)(αj〉q。利用多模压缩态理论,对态|ψ0(IR)(αj)〉q的广义电场分量的等幂次高次振幅压缩特性进行了详细研究,并仔细分析了介质的增益或吸收损耗作用对该电场分量压缩特性的影响。结果显示:增益介质中上述电场分量的压缩幅度和压缩强度减弱;而在损耗介质中,随着系数|αj|的增大,该电场分量的压缩幅度和压缩强度将随之增大,并且介质的吸收越强,光场的压缩幅度和压缩强度越大。It is constructed that three-state-superposition multimode Functional Superposition state light-field Iψ0^（IR）（αj〉q with injected multimode vacuum field along X direction spreading in the gain medium and absorb medium. The muhimode squeezed state theory is used to system research the effect of equal-power high-power ampli- tude-squeezing of the generalized electric-field component on Iψ0^（IR）（αj〉q state, then the influences of the gain and absorb spoilage effect of medium to equal-power amplitude-squeezing of the generalized electric-field component are analyzed in detail. It is pointed out that both the squeezed amplitude and the squeezed intensity of amplitude-squeezing mentioned above will diminish within the gain medium; both the squeezed amplitude and the squeezed intensity of amplitude-squeezing will increase if coefficient ｜αj｜ is increase within the absorb spoilage medium, and absorption effect is increasingly strong, then the squeezed amplitude and the squeezed intensity is increasingly big.
