摘要：
Entanglement properties of two-mode squeezed coherent states in the radiation field are investigatedaccording to the entanglement criterion [Phys.Rev.Lett.84 (2000) 2722].The dependence of entanglement on squeezeangle and squeeze parameter is discussed.It shows that the system evolves into entangled states and entanglement doesnot increase persistently with the increase of squeeze angle and squeeze parameter.There only exists a certain squeezeangle in which the entanglement exists continuously.
