摘要： A triboelectric nanogeneration module, and a combined wind turbine and a method thereof. The triboelectric nanogeneration module includes a rotating disc, and moving friction plates and fixed friction plates that are oppositely arranged outside the radial direction of the rotating disc. A nano-friction material layer is arranged on the surface of each of the moving friction plates and the fixed friction plates. Driving devices are arranged on the rotating disc in the circumferential direction at intervals. The driving devices are used for extruding the moving friction plates to move to the positions at which the moving friction plates are in contact with the fixed friction plates. The moving friction plates are connected to reset devices used for separating the moving friction plates from the fixed friction plates. The moving friction plates perform straight reciprocating movement under the action of the driving devices and the reset devices.

摘要： The present invention discloses an afterload device for ex situ heart perfusion, which includes an afterload energy storage module, a pressure regulation module and two flow rate regulators that are connected through a conduit. The afterload energy storage module includes a rigid closed container and a flexible container. The perfusion fluid flows into the flexible container from one side thereof through the conduit, and the perfusion fluid flows out from the flexible container at another side thereof as the flexible container is subjected to the action of the medium pressure in the rigid hermetic container. The pressure regulation module includes two pressure regulation valves and a compressible-medium source, for regulating the pressure range within the rigid hermetic container to be always maintained between the set diastolic pressure and the set systolic pressure.
