The radiation squeezing effect in the interaction process between the single mode squeezed vacuum field and a moving two-level atom is studied by means of solving the Schrdinger equation and numerical calculations.The results are as follows: with the increasing of the atom's speed and the parameter of field model structure,the time evolution curve rises noticeably;with the rising of the probability breadth of the atom ground state,the squeezing depth of the radiation field increases,otherwise it decreases,even there is no squeeze;the phase angle effects the time evolution curve's change like the probability breadth of the atom ground state;during the process that the compression factor becomes larger,the radiation field can not squeeze firstly,then it squeezes partially,finally the squeeze gradually disappears.
