By means of numerical calculations,squeezing effect of the field in the system of two-mode entangled coherent states interacting with a Λ-type three-level atom is investigated.The influences of the degree of entanglement of two-mode entangled coherent state optics field and mean photon numbers of two-mode optics field on squeezing effect are discussed.The results show that squeezing effect strengthens with increasing of the the degree of entanglement of two-mode entangled coherent state optics field and weakens with increasing of mean photon numbers of two-mode entangled coherent state optics field.
