layer-sliding
1.A fixed-boundary-layer sliding mode controller using the msat function is designed to guarantee the robustness.
2.The controlling acton of stratigraphical dip angle on layer-sliding intensity in folding process is explained systematically.
7.The fatigue life of self-fluxing laser cladding coatings(7.21×106) was 15 % longer than that of carburized layer(6.29×106) under conditions of 2170 MPa contact stress, 12.5 % sliding difference and lubrication with 20# machinery lubricating oil, it was due to the effect of strain-induced martensite formed under contact stress.
9.A brief introduction to scientific research in the Three Gorges Project(TGP) and the applications of research achievements is given,which include treatment of newly slited layer on the foundation of the first stage earth-rock cofferdam,dumping bottom technique of river closure in deep water,construction of cut-off walls in the second stage earth-rock cofferdams,3-D computer simulation of river closure,concrete casting alternatives and selection of major construction equipment for the second stage construction optimization of durability of raw materials of concrete,deep sliding resistance and stability of the intake dam section,the section of the intake of the power station,the intake penstock of the power station,layout and hydraulics problems of shiplocks,stability of high slopes of shiplocks,and optimization of the system structural anchor bars to reduce the risk of cracking in the concrete wall and 700MW turbine generator units.
