Abstract: A communication method and apparatus are disclosed for use in vehicle-to-everything (V2X) communications. The method includes: determining a first slot in a resource selection window, where the first slot is used to transmit a first reference signal, the resource selection window includes at least one slot, and the first slot is an unreserved slot, or the first slot is a slot reserved for transmitting a second reference signal; and sending first indication information indicating the first slot. Therefore, a same slot is not shared with a resource for data transmission, so that transmission of the first reference signal in the first slot does not interfere with data transmission in the first slot, thereby ensuring reliability of data transmission.

Abstract: The embodiments of the present disclosure provide a video processing method and apparatus, and an electronic device. The video processing method includes: acquiring a first video and first information, where the first information is used for generating a second video, and the first information comprises an identifier of an audio and editing information; acquiring the audio in a content delivery network based on the identifier of the audio; and generating the second video based on the first video, the audio, and the editing information.

Abstract: A Taiji fishway structure includes fishway pool chamber units arranged sequentially along a water flow direction, each fishway pool chamber unit includes an curved side wall, an curved deflector, and a first longitudinal side wall, a fishway vertical partition plate, and a second longitudinal side wall provided on the same side of the fishway. A head end of the curved deflector of the i-th fishway pool chamber unit connects to a head end of the curved side wall in the (i+1)th fishway pool chamber unit, and forms a fish passage vertical slot that matches target fish body size with an end of the fishway vertical partition plate in the (i+1)th fishway pool chamber unit, and water flow of the i-th fishway pool chamber unit is ejected toward the curved side wall in the (i+1)th fishway pool chamber unit through the fish passage vertical slot.

Abstract: The present application discloses a fishway with a pool head and pool tail in the field of fishway technology. The fishway includes a pool head, a main fishway, and a pool tail arranged sequentially from an upstream to a downstream. The main function of the pool head and the pool tail is to adapt to the fluctuation of the upstream and downstream water levels, so as to avoid the impact of the upstream and downstream water level changes on the main fishway. To achieve the above purpose, an upstream maintenance gate, a double-gate and dual-control working gate (dual control refers to flow control and fish passage effect control), an upstream steep-slope fishway, and fish guiding facilities are set at the pool head. A downstream steep-slope fishway, a water replenishment channel, and a downstream maintenance gate are set at the pool tail.

Abstract: The present application relates to the field of lithium ion batteries, and in particular, to a waste lithium ion battery electrolyte solution recycling method and apparatus, an electronic device and a computer readable storage medium. The waste lithium ion battery electrolyte solution recycling method includes the steps of: crushing a waste lithium ion battery; cleaning with an organic solvent; performing first filtering; performing vacuum distillation; performing first thermal decomposition; dissolving by adding an acid solution; adding soluble carbonate and/or carbon dioxide for reaction; and performing second filtering. By means of the treatment of the steps, the solvent in the electrolyte solution can be obtained from the waste lithium ion battery, and the electrolyte is recycled in the form of phosphorus pentafluoride and lithium carbonate.
