| 摘 要： | 利用多模压缩态理论，对介质中两态叠加多模叠加态光场｜ψ^（α）〉q的不等幂次Nj次方和压缩特性进行了详细的研究．结果发现当各模压缩幂次数之和为偶数时，介质中多模叠加态光场｜ψ^（α）〉q恒处于不等幂次Nj最不测不准态；而当各模压缩幂次数之和为奇数时，多模叠加态光场｜ψ^（α）〉q在一定条件下呈现出周期性变化的Nj次方和压缩效应．

| Abstract: | By using the theory of multimode squeezed states, the properties of unequal-power Nj-th power sumsqueezing of muhimode superposition state light field ｜ψ^（α）〉q with the superposition of two quantum states in medium was studied. It was found that when the sum of the squeezing power of each mode was even number, the multimode superposition state light field ｜ψ^（α）〉q was always in Nj minimum uncertainty state; when the sum of the squeezing orders of each mode was odd number, under some conditions, the multimode superposition state light field ｜ψ^（α）〉q could also present Nj-th power sum-squeezing that changed periodically in medium. |
