Abstract: The present disclosure provides a 6xxx-series aluminum alloy sheet for an inner panel of a hood, and a preparation method and use thereof. The aluminum alloy sheet includes the following compositions in percentage by weight: 0.75%-0.95% of Si, 0.15%-0.35% of Mg, 0.2%-0.4% of Fe, 0.05%-0.2% of Mn, 0.06%-0.2% of Cr, less than or equal to 0.15% of Cu, and less than or equal to 0.15% of inevitable impurities in total amount, where each inevitable impurity is less than or equal to 0.05%, the balance is Al, and an atomic ratio of Mg to Si is (0.18-0.54):1. The sheet has high formability hood. After baking, the sheet has low yield strength on the premise of maintaining strength slightly exceeding strength requirement of a support structure, and further has a low strain rate sensitivity coefficient, satisfying the pedestrian protection requirement. The aluminum alloy sheet is conducive to recycle and remanufacture.

Abstract: An in-situ tensile device for X-ray tests is provided, including: a frame including a connecting structure, where the connecting structure is configured to fixedly connect to a testing bench of a testing device; a stretching mechanism, disposed on the frame; a clamping mechanism, including two clamping assemblies arranged opposite to each other in a length direction; where the two clamping assemblies are configured to clamp two ends of a testing piece, the testing piece is provided with a testing surface, and the testing surface is disposed on surfaces of the two clamping assemblies; the stretching mechanism is drivingly connected to the two clamping assemblies to enable the two clamping assemblies to move synchronously in one of a direction approaching each other and a direction far away from each other; and the two clamping assemblies are detachably connected to the stretching mechanism. The device can improve the accuracy of test results.

Abstract: A bidirectional selecting method, between service objects and service providers, includes the steps of: after acquiring an expression data about a user, acquiring at least intentional object in a corresponding object database based on the expression data and a background information of the user to obtain a processing result; and outputting the processing result, wherein when the user is a service object, the object database is a service provider database, wherein when the user is a service provider, the object database is a service object database.

Abstract: A transaction management system includes an analysis module, analyzing a character requirement and a processing deadline of at least one transaction to be assigned, wherein the analysis module analyzes a working state of at least one character to obtain an available time, and an assignment module, communicatively connected with the analysis module to assign the character having available time before the processing deadline and meeting the character requirement to be at least one executor of the transaction.

Abstract: The present invention provides a project management method, which comprises the steps of: (A) analyzing a resource demand of the project according to a project view of at least a project; (B) analyzing an available time of the resources according to a resource view of at least a resource; (C) calling the resources to the project according to the resource demand and the available time of the resources.

Abstract: A matching inventors method, for confirming the contribution made by each inventor can be conveniently, includes steps of: I. Obtaining one of claims form a specification; II. Translating said claim to obtain a discriminated code which presents said claim; and III. Pairing said discriminated code with at least one inventor preset in at least one inventors database to determine the contribution of said inventor to said claim.
