In　Wenchuan　8.　0　earthquake,　the　420　stations　of　China　Digital　Strong　Motion　Seismic　Network　in　19　provinces　and　autonomous　regions　have　obtained　1　257　three-component　acceleration　records　of　the　main　shock.　The　preliminary　waveform　and　records　are　statisted,　and　the　results　show　that　some　records　are　incomplete,　leaving　out　the　beginning　and　the　end.　From　the　waveform　characteristics　of　strong　motion　records,　equipment　start/stop　trigger　thresholds,　and　before/after　event　storage　time,　the　reasons　for　the　above　phenomenon　are　analyzed,　and　the　prestored　reasonable　digital　strong　motion　parameters　are　proposed.　The　preliminary　studied　results　can　provide　a　reference　of　setting　parameters　for　the　digital　strong　motion　accelerographs.
