Abstract: An application upgrade method of a mobile terminal includes: acquiring an update installation package of an application required to be upgraded; modifying a unique identification of an application having a latest version; installing the application having the latest version, and generating a prompt window after a preset time for prompting whether to use the application having the latest version; if yes, controlling the application having an old version to be uninstalled and retaining the application having the latest version; and if no, controlling the application having the latest version to be uninstalled and retaining the application having the old version, when it is decided not to use the application having the latest version. A storage device and a mobile terminal are also provided.

Abstract: A screen capturing method for an electronic device is provided and includes: acquiring and parsing interface information currently displayed in an electronic device to obtain information about all view controls for a specified window; parsing the information about view controls, constructing all view controls for the specified window into a view control tree, and building a presentation interface including image views corresponding to all view controls; receiving a click instruction from a user for clicking one of the image views, removing the image view clicked by the user from the presentation interface, and saving the current presentation interface when a save instruction is received; and capturing an image of the presentation interface in the current screen and saving the captured image.

Abstract: Disclosed are a communication information hiding realization method and realization system. The method comprises: monitoring a communication information database for storing communication information in real time, and judging whether there is newly added communication information in the communication information database; when there is newly added communication information in the communication information database, acquiring a communication number of the newly added communication information, and comparing the communication number to a pre-set communication number set needing to be hidden; and when the communication number exists in the communication number set needing to be hidden, deleting or hiding the communication information corresponding to the communication number in the communication information database.

Abstract: The present disclosure provides a terminal, a view character copying method thereof, and a storage apparatus. The copying method may include: receiving a triggering operation of a user, and determining a view of which character copying needs to be executed according to the triggering operation; invoking a bottom layer interface to set an attribute of the view to be editable; receiving a clicking operation performed to the view and copying characters between a start position and an end position. Based on this method, the present disclosure may allow users to copy and paste characters in the view at will, improving user experience.

Abstract: A method and a system for disabling a non-deletable application in a mobile terminal includes detecting that an application icon on a screen of the mobile terminal is long-pressed, determining whether the application is a non-deletable application or not; when the long-pressed application is a non-deletable application, determining whether the non-deletable application is a system application or not; and prompting a user, via a prompt box in the screen, to confirm whether to disable the application or not, when the non-deletable application is not a system application but is an application in a preset core application list; responsive to confirming to disable the application, disabling the application and hiding the application icon on the screen.

Abstract: A chemical-electromagnetic hybrid propeller with variable specific impulse. Fuel gas ejected out from a spraying tube of the chemical propeller through chemical propulsion enters an ionization chamber through a first magnetic mirror tube for ionization. The fuel gas after ionization is heated up by radio-frequency ion cyclotron waves in an ion cyclotron wave heating chamber so as to improve the kinetic energy. Then a second magnetic mirror tube is used, so that ions in the fuel gas after the ionization are heated up many times in a reciprocating manner between the magnetic mirror tubes, and ejected to generate forward propulsion force. By means of the propeller, the propulsion force and the specific impulse are greatly increased.

Abstract: A method for electroplating a substrate having an aluminum alloy surface comprises: applying a zinc layer onto the aluminum alloy surface; electroplating a first copper layer onto the zinc layer from an alkaline copper electroplating solution; electroplating a second copper layer onto the first copper layer from an acid copper electroplating solution; electroplating a Cu—Sn alloy layer onto the second copper layer from a Cu—Sn electroplating solution; and electroplating a chromium layer onto the Cu—Sn alloy layer from a trivalent chromium solution. The alkaline copper electroplating solution is substantially free of cyanide ion.
