| Zusammenfassung: | The utility model discloses a supporting flat plate structure which comprises a supporting flat plate, a central objective table is arranged at the bottom end of the inner wall of the supporting flat plate, a reflector mounting screw hole is formed in the central objective table, and air holes are symmetrically formed in the inner wall of the supporting flat plate and located on the two sides of the central objective table. And sight glass mounting screw holes are formed in the edge of the supporting flat plate. According to the utility model, the supporting flat plate structure can perform independent and stable reinforced connection on the positions of the reflecting mirror and the sight glass container assembly through the arranged reflecting mirror mounting screw hole and the sight glass mounting screw hole, so that the shooting stability of the cross section of the simulation cylinder sleeve is ensured during the characteristic test of the flow field of the air passage of the engine, and a large-size air |
