The　Chinese　and　international　development　status　and　study　results　of　particle　damping　technology　are　summarized,　and　similarities　and　differences　among　non-obstructive　particle　damping　(NOPD)　,　bean　bag　damping　(BBD)　and　piston-based　particle　damping(PPD)are　given.　According　to　the　type　of　particle　damping,　its　interaction　mechanism,　computing　models,　dissipated-energy　effect　factors　and　some　other　questions　have　been　demonstrated　systematically,　and　advantages　in　application　and　its　superiority　over　viscous　damping　&　mechanical　damping　have　been　pointed　out　to　prove　its　bright　prospect　in　application　and　development　potential.　Meanwhile,　some　problems　to　be　solved　in　present　computing　model,　actual　application　and　design　of　particle　damper　have　also　been　indicated　,　and　the　research　and　development　orientation　of　particle　dampers　is　suggested　in　future.
