Abstract: A method is applied to an electronic device, and includes: obtaining content copied by a user on a first page, and determining a category to which the content belongs; obtaining a category of a second page; matching the category of the content against the category of the second page; and if a matching result is not empty, displaying at least one operation option on the second page, where the at least one operation option has a function of performing an operation for the content on the second page, so that the electronic device directly performs the function after the user selects the operation option.

Abstract: The method includes: displaying a screen projection window in at least a part of a display interface, where the screen projection window is a mirror of screen display content of a screen projection source end, and the screen display content includes a first edit box; receiving input start information from the screen projection source end, where the input start information is used to indicate that the first edit box has obtained an input focus; obtaining text content or an image that is input by an input device of the screen projection destination end, to obtain to-be-displayed content sending the to-be-displayed content to the screen projection source end; and updating the screen projection window, where an updated screen projection window is a mirror of updated screen display content of the screen projection source end, and the to-be-displayed content is displayed in the first edit box in the updated screen display content.

Abstract: A method is applied to an electronic device, and includes: obtaining content copied by a user on a first page, and determining a category to which the content belongs; obtaining a category of a second page; matching the category of the content against the category of the second page; and if a matching result is not empty, displaying at least one operation option on the second page, where the at least one operation option has a function of performing an operation for the content on the second page, so that the electronic device directly performs the function after the user selects the operation option.

Abstract: A method for service decision distribution includes obtaining, by a service distribution system, service data associated with a target service is triggered, where the service data includes service type information and user information, obtaining, by the service distribution system during a determining period of the target service, device capability information and device status information of a plurality of terminal devices associated with the user information, determining, by the service distribution system based on the service type information, the device capability information, and the device status information of the terminal devices, a target terminal device that is in the terminal devices and that is used to execute the target service or a target moment for executing the target service to implement service transfer among multiple terminal devices.

Abstract: A method is applied to an electronic device, and includes: obtaining content copied by a user on a first page, and determining a category to which the content belongs; obtaining a category of a second page; matching the category of the content against the category of the second page; and if a matching result is not empty, displaying at least one operation option on the second page, where the at least one operation option has a function of performing an operation for the content on the second page, so that the electronic device directly performs the function after the user selects the operation option.

Abstract: A human-computer interaction method is applied to an electronic device, and includes: obtaining content copied by a user on a first page, and determining a category to which the content belongs; obtaining a category of a second page; matching the category of the content against the category of the second page; and if a matching result is not empty, displaying at least one operation option on the second page, where the at least one operation option has a function of performing an operation for the content on the second page, so that the electronic device directly performs the function after the user selects the operation option. In the method, a category of copied text content is extracted and is matched against a category of a keyword, and a matched group is used as a prompt operation. The prompt operation is displayed in a form of a dialog box, to prompt a next action that may be performed by a user, so that complexity of user operations is reduced, and accuracy of pasting text information is improved.

Abstract: A defect imaging method for a lining anti-corrosion pipeline is provided, including following steps: loading an imaging excitation signal to the lining anti-corrosion pipeline under detection; acquiring an imaging excitation reflection signal and an imaging excitation transmission signal; obtaining bending mode guided waves of the imaging excitation reflection signal and the imaging excitation transmission signal respectively, and performing time reversal processing on the bending mode guided waves to obtain time-reversed signals; performing excitation reversal on the time-reversed signals to obtain excitation reversal data; performing temporal and spatial focusing processing on the excitation reversal data to obtain a vibration cloud diagram; and converting the vibration cloud diagram into a three-dimensional color point cloud diagram to image a defect of the lining anti-corrosion pipeline.
