摘要： This application relates to a method and an apparatus for identifying a topology of a power line low-voltage transformer area. The method may include: A primary node obtains characteristic data, where the characteristic data includes: first characteristic data between any two secondary nodes that have a direct connection relationship in a plurality of secondary nodes in the low-voltage transformer area. The primary node identifies the topology of the low-voltage transformer area based on the characteristic data, where the characteristic data includes at least one of delay data or channel quality data, the delay data is a first delay for transmitting information on a power line between the two nodes that have a direct connection relationship, and the channel quality data is quality of a power line channel between the two nodes that have a direct connection relationship. In this application, a capability requirement on each node is reduced. Costs are low, and universality is high. In addition, the delay data or the channel quality data does not depend on load of a power grid. This improves identification reliability and accuracy. Moreover, there is no need to send a disturbance current. This avoids interference to a power environment.

摘要： A photographing method in a long-focus scenario and a terminal are provided, and relate to the field of terminal technologies. A moving direction and a moving distance of a framing range of the terminal can be controlled, so that a target photographing object accurately moves into the framing range, to improve efficiency of interaction between a user and the terminal. The method specifically includes: When a zoom magnification used by a terminal is greater than or equal to a preset magnification, a photographing interface displayed by the terminal includes a first viewfinder frame and a second viewfinder frame. The first viewfinder frame is used to preview an image captured by a long-focus camera. A framing range of the second viewfinder frame is greater than a framing range of the first viewfinder frame, and a framing range the same as that of the first viewfinder frame is marked in the second viewfinder frame. A user can adjust the framing range of the first viewfinder frame by using the second viewfinder frame and an adjustment control without moving the terminal.

The box (11) includes a first cover body (117), a second cover body (118), and a cover plate (13). A first chamber is formed between the sounding unit (12) and the inner bottom wall of the first cover body, and a sound hole (113) is disposed in the first cavity (111). A second cavity (112) is formed between the sound generation unit (12) and the second cover body (118). The sound generation unit (12) includes a diaphragm (123). A resonant cavity (114) with a through hole (116) on one side is formed in the first cover body (117), the cover plate (13) covers the through hole (116), and a microhole (115) is disposed. Airflow enters the second cavity (112) through the microhole (115), so that the diaphragm (123) does not collide with a magnetic part (125) in the sound generation unit (12) during vibration.
