    摘要: A screen is disclosed which, in certain aspects, has screening material between opposed frame sides and one or more lower strips beneath the screen. In one aspect these strips are only inteconnected via their ends and not along their lengths. In certain aspects, a plurality of lower strips are bonded to the screen and extend across the screen from one frame side to the other. In one aspect one or more of the strips has one, two, or more humps or ridges corresponding to one or more corrugations in a corrugated perforated plate and/or corrugated screen assembly which is on the plate or, with no plate present, on the strips. In another aspect instead of the strips a solid corrugated perforated plate is used. In one aspect openings or perforations through the plate are triangular. In one aspect the screen is undulating screening material and lower portions of the screening material are bonded to a plate or to strips. Optionally screen mounting hooks or frame edges or screen edges may be used with such screens. A screening apparatus or shale shaker is disclosed which uses such plates and screens.
