摘　　要：本文研究了由属于不同表示的两个双模ＳＵ（１，１）相干态线性迭加的压缩增强效应．发现相干态的线性迭加，以及的线性迭加均可产生增强的压缩。且当时，后者的压缩增强程度要大于前者，并对此时产生这两类送加态的物理机制进行了讨论。In this paper,we investigate the enhanced squeezing via superpositions of twomode SU(1, 1) coherent states from two different representations.It is shown thatthe linear combinations of two mode SU(1,1) coherent states|ξ;K> and|ξ;K, and the linear combinations of|ξ;K| and |ξ;k + 1>can be more highly squeezed than the single coherent state |ξ;k> .Furthermore, when k =, the second classof superposition states exhibits a greater degree of enhanced squeezing than thefirst one. Physical mechanisms for generating such two classes of superposition states for this case are also studied
