主　　题：two-mode displaced excited squeezed vacuum state Weyl ordering Wigner function marginal distribution entangled state representation 

摘      要：In this paper,two-mode displaced excited squeezed vacuum states (TDESVS) are constructed and theirnormalization and completeness are *** the entangled state representation and Weyl ordering formof the Wigner operator,the Wigner functions of TDESVS are obtained and the variations of Wigner functions withthe parameters m,n and r are ***,two marginal distributions of Wigner functions of TDESVS areobtained,which exhibit some entangled properties of the two-particle s system in TDESVS.
