Abstract: The present disclosure discloses a method for automatically identifying south troughs by improved Laplace and relates to the technical field of meteorology. The method includes the following steps: acquiring grid data of a geopotential height field; calculating a gradient field of the geopotential height field in an x direction; searching for a turning point where a gradient value turned from being negative to being positive, and cleaning the gradient field; calculating a divergence of the x direction to obtain an improved Laplacian numerical value L?; performing 0,1 binarization processing on the L? to obtain a black-and-white image and a plurality of targets of potential troughs, merging the black-and-white image and the plurality of targets of the potential troughs by expansion, recovering original scale through erosion, and selecting an effective target through an angle of direction of a contour and an axial ratio.

Abstract: A liquid dispenser sensing distance self-learning method includes in response to a self-learning request, entering a self-learning mode. The method also includes, in the self-learning mode, determining a shortest distance between a reference object and a sensing component; determining and storing a sensing distance based on the shortest distance; and identifying, by a first indication device, a state of the self-learning mode. The method also includes, in response to a sensing request, entering a sensing mode; obtaining a detected distance between the reference object and the sensing component; comparing the detected distance with the sensing distance; and identifying, by a second indication device, a comparison result of the detected distance and the sensing distance.

Abstract: A patching method includes generating an original image through compilation for a plurality of files. If a first file in the plurality of files changes, a new index mode of the first file or new data of the first file may be appended to an end of an original image to update the first file to obtain a new image.

Abstract: An application icon moving method and an electronic device, where after a first application is installed in the electronic device, the electronic device displays an interface including an icon of the first application, when receiving a second operation from a user on the icon of the first application, the electronic device displays a management menu around the icon of the first application, where the management menu includes one or more of an identifier of a sub-screen of a home screen of the electronic device or an identifier of a folder included in a sub-screen. The electronic device receives a third operation from the user on a first identifier included in the management menu, and move, in response to the third operation, the icon of the first application to a sub-screen or a folder corresponding to the first identifier.

Abstract: A terminal device displays a first interface including a preset icon (301), where the preset icon is displayed in a floating manner; the terminal device displays a first application list when detecting an input first user operation on the preset icon (302); the terminal device divides a screen of the terminal device into two or more subscreens when detecting an input second user operation on a first application in the first application list, and the terminal device displays the first interface and the first application on a first subscreen and a second subscreen respectively, where the first subscreen and the second subscreen are included in the two or more subscreens. A display screen can be quickly divided into a plurality of subscreens, and different content is displayed on different subscreens.

Abstract: When a repair problem exists in a case of a fully loaded partition, or when a feature of a terminal device needs to be expanded but there is no remaining space in a related partition, the terminal device may search for and download a patch file from a server, and a compressed empty device (loop) is used to expand the feature. In some conditions, the empty loop device and the fully loaded partition may be combined to form a new device. In some other conditions, based on a packaging technology in a disk block dimension, a changed file is repackaged in the disk block dimension.
