Abstract: Disclosed are a method and device for evaluating damage caused by secondary stress to a vacuum vessel, a terminal device, and a medium, to perform following steps: obtaining secondary stress of a vacuum vessel that passes a primary-stress failure evaluation; obtaining structural damage parameters of the vacuum vessel when determining, based on evaluation parameters for the primary-stress failure evaluation of the vacuum vessel and the obtained secondary stress, that the vacuum vessel meets a precondition for a progressive deformation; and determining, based on the obtained structural damage parameters, whether the vacuum vessel meeting the precondition for the progressive deformation experiences structural damage due to the progressive deformation. In this way, a vacuum vessel of a nuclear fusion reactor can be evaluated based on damage caused by the secondary stress.

Abstract: The present invention provides a method for preparing graphene, including reacting graphite in an acid solution in which an oxidant is present so as to obtain a graphene. Compared with the prior art, the advantages of the present invention reside in that, the graphene prepared by the method of the present invention has excellent quality and substantially increased yield and production rate, as compared with mechanical stripping, epitaxial growth, and chemical vapor deposition; and the graphene prepared by the method of the present invention has significantly improved quality, substantially reduced structural defects, and significantly increased conductivity, as compared with oxidation-reduction preparation in the solution-phase; besides, the method is also advantageous for a simple process, mild conditions, low cost, and very easy for scale production.

Abstract: A method and system reuse data logs generated from testing of programmable devices in order to provide an input file of parameter values and settings for use in automatically configuring a device simulator. The programmable device testing process generates a data log output with data formatted so that parameter data are associated with unique variable labels. The data log output file is processed in a parser operation that filters out private and unnecessary information, organizes the data and generates a simulation input file in a format compatible with the simulator. The process can be fully automated.
