Abstract: A rocker polishing apparatus for full-aperture deterministic polishing of a planar part includes a control system, a substrate, a lifting plate, a polishing module and a measuring module. The polishing module and the measuring module are arranged on the substrate. The lifting plate is arranged between the polishing module and the measuring module. The polishing module includes a rocker mechanism, a polishing pad surface dressing mechanism, a polishing pad surface profile measuring apparatus and a continuous polishing pad mechanism. The apparatus allows the material removal rate distribution of the planar part and the surface profile of the planar part be in the normalized mirror symmetry relationship by controlling the material removal rate distribution on the surface of the planar part, thereby implementing the deterministic polishing of the planar part and ensuring the efficient convergence of the surface profile of the planar part in the polishing process.

Abstract: A floating breakwater and wind energy integrated system used for offshore aquaculture. The system contains the wind turbine system, the floating breakwater system, and offshore aquaculture system. The combination of wind turbine, floating breakwater system and offshore aquaculture system makes full use of the floating breakwater, thus decrease the wave load on the floating cage. In addition, the floating breakwater offers a supporting platform to the floating wind turbine, which effectively reduces the costs of the wind turbine. Meanwhile, a power autarkic offshore aquaculture system may be realized by using the electrical energy generated by the turbine. Compared with the simple offshore aquaculture system, the utilization rate of the sea per unit becomes even higher while the costs of the floating wind turbine becomes even lower.
