摘　　要：利用多模压缩态理论 ,研究了文献 [1]构造的两类多模叠加态的广义非线性振幅不等幂次压缩特性。结果找到了这两类态存在振幅不等幂次压缩效应的条件、发现两类态之间呈现“相似压缩”和“简并压缩”现象 ,表明它们是典型的多模非经典光场 ,文献 [1]是本文在一定条件下的特例。By utilizing the theory of multi-mode squeezing state,the author of the present paper studied the properties of generalized nonlinear amplitude unequalled-power squeezing in the two types of multi-mode superposition state constructed in document .It is found both some certain conditions which the two types of multi-mode superposition states display amplitude unequalled-power squeezing effect and the new phenomena of similitude squeezing and degenerate squeezing.The results show that those are two kinds of typical multi-mode unclassical light fields.These mentioned above demonstrate that the document is only the specific example of this paper under the certain conditions.
