The Hamiltonian operator of a system of V-type three-level atomic Bose-Einstein condensate interacting with two-mode squeezed coherent light field is analyzed in terms of the lattice-liquid model. It is indicated that the contribution of the interaction between atoms to the Hamiltonian in the literature is unreasonable,so the Hamiltonian operator is improved and the squeezing properties of two-mode squeezed field interacting with V-type three-level atoms are studied. The results show that two quadrature comonents of light can be squeezed periodically and that maximum depth of squeezing is closely related to the initial squeezing parameter of light and that the duration is determined by the frequency of two-mode field.
