Abstract: An information processing method includes receiving a user input, the user input representing a trajectory, performing recognition on the trajectory to obtain a matching result based on matching in a database, recording the trajectory to generate an image including the trajectory, and outputting a candidate option. The candidate option includes the matching result and an identifier of an image.

Abstract: An electronic cigarette, an atomization assembly and an atomization component for the same. The atomization component comprises a porous base, a first film, and a second film. The porous base material comprises an atomization surface. The first film and the second film are sequentially formed on the atomization surface. At least one of the first film or the second film is used for generating heat when charged, so as to heat and atomize an e-liquid on the atomization surface.

Abstract: A method for recovering description information, or a method for caching data in a database, includes: judging whether a database is closed normally after the last operation; if the database is not closed normally, traversing each data block in a level-2 cache, where corresponding disk location information is saved in a header of each data block; obtaining a data block in a disk according to the disk location information; and when the obtained data block in the disk is the same as a corresponding data block in the level-2 cache, establishing description information according to location information of the data block in the disk and location information of the data block in the level-2 cache, where the description information is used to describe correspondence between the location information of data in the disk and the location information of data in the level-2 cache.
