A　simplified　scheme　is　proposed　for　the　test　of　quantum　nonlocality　of　the　type　described　by　Hardy　[Phys.　Rev.　Lett.　71　(1993)　1665].　In　the　scheme　two　appropriately　prepared　atoms　are　simultaneously　sent　through　a　cavity　and　dispersively　interact　with　the　cavity　field.　Then　state-selective　measurements　are　performed　on　these　atoms,　which　may　reveal　quantum　nonlocality　without　using　Bell　inequality.　We　also　propose　a　simple　scheme　for　the　generation　of　multi-atom　entangled　states.
