Abstract: A method for controlling stability of gas flow at the periphery of a blast furnace, including the following steps: constructing a database; and selecting blast furnace operating parameters satisfying a first preset condition from the database to generate an instruction for setting the blast furnace operating parameters for a next operating stage. The first preset condition includes: PD<a preset value PD0, and the blast furnace operation parameters corresponding to a minimum value of PU are selected when the condition is satisfied.

Abstract: A determination method for a chroma intra prediction mode includes: performing a simple RDO calculation on a luminance value of each pixel of an image block to obtain multiple luminance candidate modes; determining multiple chroma candidate modes according to one of the luminance candidate modes and a chroma simple RDO result calculated by performing a simple RDO calculation on a chroma value of each pixel of the image block; performing a full RDO calculation of the multiple luminance candidate modes on the luminance value of each pixel in the image block to select a luminance target mode; performing a full RDO calculation of the multiple chroma candidate modes on the chroma value of each pixel of the image block to a obtain chroma full RDO result; and determining a chroma target mode according to the luminance target mode and the chroma full RDO result.

Abstract: This application discloses a trip sharing method and apparatus, a device, a storage medium, and program product, and relates to the field of computer and the Internet technologies. The method includes displaying, shared information of a first trip created by a first user account in the mini program in a display interface of the social networking application, the first trip being a trip created by a car owner and waiting for participation by a passenger; displaying a trip detail interface of the mini program in a case that the mini program determines, after receiving the trip presentation instruction, that a second user account has permission to participate in the first trip; and displaying a trip confirmation interface in the mini program in response to an operation on the trip participation control, the trip confirmation interface displaying trip information of the participated first trip.
