In　order　to　put　numerous　experimental　data　of　drinking　water　treatment　into　practice,　effective　methods　are　studied.　The　article　uses　frame　representation　and　case-based　reasoning　to　construct　an　analysis　system.　The　resourcefulness　expert　software　developed　by　ourselves　combines　with　the　database　of　the　test　data　in　the　863　project,　which　can　analyze　experimental　data　and　apply　the　results　to　production.　The　result　shows　that　CBR　is　very　suitable　for　analyzing　experimental　data　of　the　water　treatment　field,　where　there　is　no　complete　theory.
