摘　　要：发现用Weyl编序以及有序算符内的积分技术可以直接推导出异质量两粒子的纠缠态表象,其纠缠特性可以通过Schmidt分解得以显现.用此表象给出了一类新的单-双模组合压缩态以及相应的压缩算符.It was found that the entangled state representation of two particles with unequal masses can be directly derived by the Weyl correspondence and the technique of integration within an ordered product of operators.The entanglement properties can be achieved through its Schmidt decomposition.With this representation,a kind of new one-and two-combination squeezed state and corresponding squeezing operator was obtained.

关 键 词：异质量的纠缠态表象 Schmidt分解 压缩态
