Abstract: A structural design method of a product is provided. The method includes obtaining a preliminary design of a subsurface mesh structure by filling a body model of the product with spherical cells at preset positions of the body model and performing an finite element analysis and optimization; and optimizing, through a design method for optimizing functions, filling features of the spherical cells based on a simulation analysis so that the structure of the product satisfies a preset target.

Abstract: A method and device for predicting a number of confirmed cases of an infectious disease, an apparatus, and a storage medium. The method includes obtaining a number of historical confirmed cases corresponding to each of multiple historical time periods adjacent to a time period to be predicted, adding a number of historical confirmed cases corresponding to a current historical time period with numbers of historical confirmed cases corresponding to previous target historical time periods to determine a historical cumulative number corresponding to each current historical time period, determining a predicted cumulative number corresponding to the time period to be predicted based on the historical cumulative number corresponding to each current historical time period, and determining a differential value between the predicted cumulative number corresponding to the time period to be predicted and a historical cumulative number corresponding to current target historical time period adjacent to the time period to be predicted, and taking the differential value as a predicted confirmed number of the time period to be predicted.

Abstract: A method for arranging an emergency rescue station includes obtaining coordinates of at least one rescue center, coordinates of at least one hospital, and coordinates of at least one object to be rescued within a preset range; determining the number of remaining beds in the at least one hospital, and determining a rescue number corresponding to the at least one object to be rescued; determining whether the rescue number is less than or equal to the number of remaining beds; and in response to the rescue number being less than or equal to the number of remaining beds, determining coordinates of a newly added rescue center based on the coordinates of the at least one rescue center, the coordinates of the at least one hospital, and the coordinates of the at least one object to be rescued.

Abstract: The present application discloses a method for preparing optical metasurfaces, wherein the method is performed based on nano-imprinting, and the template used in the method is an imprinting template with patterns of meta-atoms. The method for preparing optical metasurfaces provided by the present application can replace the electron beam lithography method used in fabricating meta-atoms, greatly reducing the costs, and greatly reducing the production time. The method provided by the present application significantly improves the production cost and the production time, achieving a low-cost, large-scale fabrication of metasurface-based optical elements within a short time, and having good industrialization prospects.
