Abstract: A pyram-shaped deep-sea pressure-resistance shell and a design method therefor. The shell comprises a conical shell, an annular combined shell, a cylindrical shell, a flange bolt, and a perforated thick plate; a bottom end of the conical shell is connected with a top end of the annular combined shell, the conical shell being in communication with an interior part of the annular combined shell; the perforated thick plate blocks the bottom end of the annular combined shell, the perforated thick plate and the annular combined shell being connected by means of multiple flange bolts; the cylindrical shell is disposed inside the annular combined shell, a lower end of the cylindrical shell being inserted in a gap between the annular combined shell and the perforated thick plate.

Abstract: Methods and computer systems for storing a query plan in a cache are provided. The method can include: determining a use frequency of the query plan; determining a target storage layer for storing the query plan based on the determined use frequency, wherein the cache includes at least two storage layers and each of the storage layers is associated with a compression level of query plans; processing the query plan according to the compression level of the target storage layer; and storing the processed query plan in the target storage layer.

Abstract: Provided are a method and apparatus for applet page rendering, an electronic device and a storage medium. The method for applet page rendering includes steps described below. Original incremental rendering is performed on an applet page based on a pre-obtained first drawing result of the applet page to obtain an original incremental rendering result of the applet page. Rendering is performed on the applet page based on the pre-obtained first drawing result of the applet page, the original incremental rendering result of the applet page and a pre-obtained initial incremental rendering result of the applet page.

Abstract: The technical solutions relate to the technical field of compilation of applications, and particularly to the technical field of mini programs. A developer tool constructs a first compilation result of the hosted APP before compilation optimization and a second compilation result of the hosted APP after the compilation optimization respectively based on a source code of the hosted APP, and uploads them to a management platform. The management platform sends the corresponding compilation results according to environment data of the hosted APP running environment provided by the host APP, so that the host APP uses the hosted APP running environment provided by the host APP to run the obtained compilation result.
