4.Experimental results indicate the efficiency and feasibility of DCO, and also show that DCO can overcome the SPSE (space-performance saturation effect) of materialized views in some degree.
5.Aim at the complexion of national research focus on the outer layer control, the paper introduce the Space Vector Pulse Width Modulate and deadbeat control into the active power filter’s inner layer control, and analyses its’ principium and simulate its’ controlled method. The result indicate the Space Vector Pulse Width Modulate and deadbeat control not only be prone to realize digital computer control, but also can excel the traditional method in the aspect of performance.
9.The researches into the Bohaiwan basin indicate that the structural slope_break zone in the fault subsidence lacustrine basin constrained the change in the accommodation space of the basins, controlling the development of the depositional sequence and the distribution of the depositional system tracts and the sand bodies.
