A　scheme　for　remote　preparation　of　a　two-atom　entangled　state　is　presented,　which　is　based　on　the　simultaneous　nonresonant　interaction　of　atoms　with　a　single-mode　cavity　field.　In　view　of　the　fact　that　two-particle　entanglement　is　more　easily　generated　than　three-particle　entanglement,　the　scheme　prepares　a　two-atom　entangled　state　via　two　pairs　of　two-atom　entangled　state　as　the　quantum　channel.　Let　two　identical　atoms　Alice　possesses　interact　with　a　single-mode　cavity　field　simultaneously.　Alice　knows　the　state　she　wants　to　prepare.　She　selects　a　proper　interaction　time,　measures　the　states　of　the　atoms　she　possesses,　and　informs　Bob　of　her　measurement　through　a　classical　channel.　Bob　introduces　an　identical　auxiliary　atom　and　a　single-mode　cavity　field　in　vacuum　state　to　achieve　the　scheme.　The　scheme　is　insensitive　to　the　cavity　field　states　and　cavity　decay.　The　preparation　can　be　achieved　in　a　simple　way.　Based　on　current　cavity　quantum　electrodynamics　technique,　the　scheme　can　be　realized　experimentally.
