Abstract: The present application discloses a method and an apparatus for solar power generation through gas volumetric heat absorption based on characteristic absorption spectrum. A radiation energy conversion device absorbs concentrated solar radiation and converts radiation energy into thermal energy; the thermal energy is transferred to the other side of the radiation energy conversion device and then is converted into radiation energy; and the energy is transferred in a receiver cavity. The working gas from the outlet of a recuperator flows into the receiver cavity and absorbs the radiation energy. The heated working gas with high temperature flows into a turbine, doing shaft work through expansion. The expanded working gas flows through the recuperator to exchange heat. The working gas flows into a cooler, a compressor and the recuperator in sequence, and then flows into a receiver cavity to be heated volumetrically, completing a thermal power cycle.

Abstract: Disclosed is a piston device, comprising a piston body and a baffle plate of which the surface is provided with openings, wherein the baffle plate is arranged in the piston body and divides the piston body into an upper first area C and a lower second area B. Further disclosed is a pressure regulator which comprises the piston device. The piston device is beneficial for improving the stress balance of the first area and the second area, thereby improving the stability of the overall system.

Abstract: A method of receiving a file including receiving a file and receiving at least one tag path associated with the file. The tag path has a lowest node and a highest node and each the node having a tag vector. The method also includes selecting at least one storage path for which a similarity between the tag vector of the lowest node and the tag vector of the highest node exceeds a predetermined threshold and storing the file under the storage path.

Abstract: Apparatus and method for transmitting file and apparatus and method for receiving file. The apparatus for receiving a file includes: a receiving device configured for receiving a file and at least one tag path associated with the file; a path selection device configured for selecting from candidate paths at least one path where a similarity between the tag vector of the lowest node and the tag vector of the highest node in each of the tag path exceeds a predetermined threshold, as a storage path; and a storage device configured for storing the file under the storage path.
