Abstract: This application discloses a data compression method and apparatus. The method includes: obtaining m data blocks in a data area of a readable and writable file system; compressing the m data blocks by using a preset compression algorithm, to sequentially obtain n compressed data blocks, where first capacities of the compressed data blocks are the same, and the first capacity represents a quantity of bytes of compressed data that can be included in the compressed data block; and establishing a first index of each of j data blocks corresponding to an ith compressed data block in the n compressed data blocks, and recording a mapping relationship between first indexes and the j data blocks. The first index is used to identify a storage location, in a storage medium, of each data block included in the j data blocks, and attribute information included in each of the j data blocks.

Abstract: Embodiments of this application disclose an incoming call alert method and a terminal. The incoming call alert method includes: receiving an incoming call request; and invoking an audio/video player of a system to play audio/video corresponding to the incoming call request. The audio/video player is disposed in a system of the terminal in the embodiments of this application, so that when the terminal receives the incoming call request, the system of the terminal can play the audio/video used for incoming call alert. In this way, the terminal can alert a user by playing the audio/video without occupying additional system resources. In addition, an animation of the video and a caller ID display interface that are displayed by the terminal are integrated in terms of a visual effect, thereby improving use experience of the user.

Abstract: An antenna includes a first element, a second element, and a reactance-adjustable component. The first element receives an excitation current through an electrical connection to an antenna feeder, and the second element generates an induced current through electromagnetic induction of the first element. The reactance-adjustable component is disposed at an end of the first element close to a reference plane, and/or the reactance-adjustable component is disposed at an end of the second element close to a reference plane. The reference plane uses a connection point between the first element and the antenna feeder as an origin point and is perpendicular to an axial direction of the first element. The reactance-adjustable component has an adjustable reactance value and is configured to adjust a phase difference between an excitation current and an induced current, where the phase difference has an association relationship with a target angle of radiation of the antenna.

Abstract: Embodiments provide a frequency selective surface (FSS). The FSS includes uniformly arranged FSS units. Each FSS unit includes a dielectric slab, a cross-shaped metal patch, and N square-ring metal patches. The cross-shaped metal patch is adhered to a first surface of the dielectric slab, and divides the first surface of the dielectric slab into four parts. Each part has a same size and a same quantity of the square-ring metal patches. The N square-ring metal patches are adhered to the first surface of the dielectric slab, and are arranged uniformly, and N is a positive integer power of 4. Lengths of the cross-shaped metal patch in two mutually perpendicular directions are equal, and both a length in each direction and a width of a gap between adjacent patches need to meet a specific condition.
