Abstract: This application discloses a method including a transmit end that generates and sends a physical layer protocol data unit (PPDU), and a receive end that receives the PPDU and parses the PPDU. An enhanced directional multi-gigabit (EDMG) modulation field in the PPDU includes a channel estimation field (CEF), the CEF includes a CEF sequence, and a length of the CEF sequence is m, where m is determined based on a quantity of bonding channels and a quantity of subcarriers included on a channel. When a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) technology is introduced into a 60 GHz WLAN standard, an applied CEF sequence included in a CEF can be determined, and DFT-S-OFDM transmission is further performed by using the CEF sequence. In this way, a PAPR of a WLAN system can be reduced while frequency division multiplexing for a plurality of users is supported.

Abstract: A display panel mainly comprises a substrate, a driving layer, a plurality of first electrodes, a light-emitting functional layer and a second electrode, wherein the substrate has a first pixel region and a second pixel region; the driving layer is arranged on one side of the substrate, and an orthographic projection thereof on the substrate covers the first pixel region and the second pixel region, and the driving layer located in the first pixel region is provided with recessed regions; the plurality of first electrodes are distributed in an array on the side of the driving layer that faces away from the substrate, both the first pixel region and the second pixel region are provided with the first electrodes, and the first electrodes and the recessed regions are distributed at intervals; the light-emitting functional layer covers the first electrodes; and the second electrode covers the light-emitting functional layer.

Abstract: Disclosed is a fitting structure of a water outlet device. The fitting structure comprises a fixed block, hoses, and joints. A peripheral of the fixed block comprises first position holes configured to be fixedly disposed with the hoses. The joints are fixedly connected to first ends of the hoses disposed above an upper surface of the fixed block, and each of the joints comprises a first water outlet passage and a second water outlet passage in communication with the first water outlet passage. An axis of each of the first water outlet passages and an axis of a corresponding one of the hoses is coaxial. The second water outlet passage is parallel to and is staggered with the first water outlet passage by a preset distance. The joints are staggered with the hoses by the preset distance in a radial direction and an outward direction of the fixed block.

Abstract: The present disclosure discloses a fixing device and a faucet installation device. The fixing device comprises a base and a pressing block mechanism. The pressing block mechanism comprises two pressing plates. The two pressing plates are respectively connected to a locking rod, and an inner side wall of the base protrudes to define two connecting bases. At least one of the locking rods is configured to move relative to the base between a working state and a movable state. Movement of the at least one of the locking rods between the working state and the movable state cooperates with the change of the pressing block mechanism between the unfolded state and the folded state.

Abstract: A coating material, including a bottom layer, a middle layer and a surface layer. The bottom layer is an epoxy mortar having a thickness of between 1 and 3 mm, the middle layer is an epoxy resin adhesive having a thickness of between 0.1 and 0.5 mm, and the surface layer is a nanomaterial-modified polyaspartic having a thickness of between 0.3 and 0.5 mm. The epoxy resin adhesive has a viscosity of between 50 and 200 mPa·s.
