Abstract: Disclosed are an interactive information processing method, an electronic device and a storage medium. The method includes establishing a correspondence between a multimedia data stream and a display text generated based on the multimedia data stream; presenting the multimedia data stream and the display text based on the correspondence; and in response to detecting a triggering operation triggering a display content in the display text, adjusting, based on a timestamp corresponding to the display content and the correspondence, the multimedia data stream to navigate to a playback position corresponding to the display content; the display content comprises a text corresponding to speech in the multimedia data stream; and the display text and the multimedia data stream are displayed on different display areas of a page respectively, and a display area occupied by the display text is not superimposed on a display area occupied by the multimedia data stream.

Abstract: Disclosed are an interactive information processing method, an electronic device and a storage medium. The method includes establishing a position correspondence between a display text generated based on a multimedia data stream and the multimedia data stream; and presenting the display text and the multimedia data stream corresponding to the display text based on the position correspondence.

Abstract: A quasi-macroscopic cold field emission electron gun and a manufacturing method thereof are provided, which includes a filament device and an electron gun base, wherein the filament device includes a cold cathode filament and a conductive capillary tube, the cold cathode filament passes through one end of the conductive capillary tube and is crimped through a pressing groove device, the other end of the conductive capillary tube is connected to the electron gun base, and the end of the cold cathode filament is the electron emission end. Through the coaxial nesting and pressing deformation of quasi-macroscopic carbon fiber and metal tube and using of the non welding electrical connection method, this technology avoids the problem that it is not easy to form a reliable electrical connection during the welding process due to the poor wettability between carbon fiber and metal.
