The specification provides a vector graph index merging method and device, the method comprising: obtaining a plurality of vector graph indexes to be merged; wherein each node in the vector graph index represents a vector, and each edge represents that the vectors represented by the nodes connected by the edge are similar; for each target vector in each target vector graph index, determining the vectors similar to the target vector from each vector graph index based on an approximate nearest neighbor search algorithm to form a cross-graph candidate neighbor set of the target vector; based on the cross-graph candidate neighbor set of each vector in the plurality of vector graph indexes, constructing a global neighbor graph; wherein each node in the global neighbor graph represents each vector in the plurality of vector graph indexes, and each edge represents that the vectors represented by the nodes connected by the edge are similar; and converting the global neighbor graph into a merged graph index that can be used for approximate nearest neighbor search.

The application relates to the technical field of accelerators, and particularly discloses a beam merging system based on a double-beam deflection iron, which comprises first solenoids, a second solenoid and a double-beam deflection device; the first solenoids are arranged in parallel and each has a first beam channel; the second solenoid has a second beam channel; the double-beam deflection device is arranged between the first solenoids and the second solenoid and is configured to receive beams emitted from the first solenoids and the second solenoid; the double-beam deflection device has two third beam channels corresponding to the first beam channels one by one, and is used for deflecting the two received beams to the central axis direction of the second beam channel; and the second solenoid is used for merging the beams emitted from the third beam channels; the beam merging system based on the double-beam deflection iron can efficiently and accurately merge two beams.

This invention provides a method and related products for converting payload files in heterogeneous databases. The method includes: in response to a conversion command, obtaining a payload file from the heterogeneous database; parsing the payload file to obtain a parsing result; obtaining an ordered index list corresponding to a target file in a local database, the target file being used to store the converted payload file; determining the target file to be written based on the ordered index list; converting the parsing result to obtain a conversion result recognizable by the local database; and writing the conversion result to the target file. This method enables the conversion of payload files between heterogeneous databases, thereby supporting further processing of payload files by domestic databases.
