Abstract: A composite fiber includes a porous silicon phase including elemental silicon and a porous carbon phase including elemental carbon. The silicon phase and the carbon phase form an intertwined network structure in the composite fiber such that each of the silicon phase and the carbon phase is interconnected and continuous throughout the composite fiber. The silicon phase and the carbon phase together constitute at least 50 wt % of the composite fiber.

Abstract: Disclosed are an audio and video data processing method, a live streaming apparatus, an electronic device, and a storage medium. A media stream is acquired, a difference value between a current media frame timestamp and a previous media frame timestamp in the media stream is acquired, and an upper and lower limit range of the difference value is acquired; the current media frame timestamp is output when the difference value is within the upper and lower limit range; a standard media frame interval of the media stream is acquired if the difference value is not within the upper and lower limit range. The problem of abnormal playback of a player caused by an inhomogeneous timestamp of an audio and video frame is solved. An accumulation error is also balanced through forward compensation and reverse compensation, so as to prevent the accumulation error from accumulating and increasing.

Abstract: A composite fiber includes a porous silicon phase including elemental silicon and a porous carbon phase including elemental carbon. The silicon phase and the carbon phase form an intertwined network structure in the composite fiber such that each of the silicon phase and the carbon phase is interconnected and continuous throughout the composite fiber. The silicon phase and the carbon phase together constitute at least 50 percent by weight of the composite fiber.

Abstract: The present invention relates to an encoder with touch screen. It includes a shell body, and a printed circuit board (PCB board) is disposed in the shell body. The shell body is provided with a touch screen, and the PCB board is provided with a processor, an audio decoder, a video converter, a 4G module, a Flash memory and a memory module. The present invention can be touch controlled by adopting the touch screen; the heat dissipation effect is good; and the working is stable.
