Abstract: An anaerobic-AO-SACR combined advanced nitrogen removal system for high ammonia-nitrogen wastewater, in which high ammonia-nitrogen wastewater first enters an anaerobic reactor to remove most of organic matters from the wastewater, effluent water enters an AO reactor for nitrogen removal by pre-denitrification in an anoxic zone and for removal of the remaining organic matters and nitrification of ammonia nitrogen in an aerobic zone, and then the effluent water enters an intermediate pool. Meanwhile, under the control of a water quality testing device and a PLC controller, a part of raw water is introduced into the intermediate pool to adjust the carbon nitrogen ratio of the wastewater.

Abstract: Provided are a display panel, a detection device therefor, and a display device. In an embodiment, the display panel includes an array layer, along a thickness direction of the display panel, the array layer including first and second conductive layers, and at least an insulating layer being located between the first and second conductive layers; a light-emitting element located at a side of the array layer facing a light-exiting surface of the display panel; and a first through-hole. In an embodiment, the first and second conductive layers are connected to each other through the first through-hole, and at least one first through-hole is reused as an alignment connection hole; and/or, along the thickness direction of the display panel, orthographic projections of at least two first through-holes onto a plane of the light-exiting surface of the display panel have different shapes.

Abstract: The technology of this application relates to a high electron mobility transistor, including a substrate and a GaN channel layer and an AlGaN barrier layer that are sequentially stacked on the substrate. Two through holes that are spaced apart from each other are opened in the AlGaN barrier layer. Each of the through holes penetrates the AlGaN barrier layer along a thickness direction of the AlGaN barrier layer, and a hole wall of each of the through holes has at least one stepped structure. Each of the through holes has an upper opening away from the substrate and a lower opening close to the substrate. The high electron mobility transistor further includes a source and a drain, where the source and the drain each fill up a through hole and are directly in contact with and connected to the GaN channel layer.

Abstract: A method for link fault detection and recovery based on Address Resolution Protocol (ARP) interaction, including: configuring an IP address and a mask code, a strategy routing or static routing module and an ARP module for network devices of a home terminal and an opposite terminal; the strategy routing or static routing module regularly inquiring whether an ARP entry to which a next hop corresponds exists, if the ARP entry exists, a link being available, otherwise, notifying the ARP module to perform keepalive on the next hop; and the ARP module performing a process of keepalive on the next hop, and after performing keepalive on the next hop, notifying the strategy routing or static routing module to judge whether the link is available. Further, a device for link fault detection and recovery based on ARP interaction.

Abstract: The present invention provides a distributed method for implementing Link Aggregation Control Protocol (LACP) standard state machines, wherein the method includes: after receiving a message, a physical port transmits it to a receive machine; the receive machine, a periodic transmission machine, a multiplexer (MUX) machine, and a transmit machine are triggered to operate in turn; the selection logic on a master controller is triggered to operate, and the processing of the message is completed according to the physical link selection state of the selection logic on the master controller; wherein, the receive machine, periodic transmission machine, MUX machine, and transmit machine operate on the link card at which the physical port is located, and the selection logic operates on the master controller.

Abstract: A device-level redundancy protection method and system based on Link Aggregation Control Protocol (LACP), wherein the method includes: configuring same parameters for the Link Aggregation Group (LAG) on a first device (LAGP1) and the LAG on a second device (LAGP2), and transmitting an LACP Data Unit (LACPDU) message carrying the parameters to the LAG on a customer edge (LAGC). After receiving the LACPDU message, the LAGC adds physical links respectively connected with the LAGP1 and the LAGP2 into the same Aggregator on the customer edge (AGGC). The LAGP1 and the LAGP2 respectively add physical links connected with the LAGC into the Aggregator of themselves to form a virtual Aggregator (AGGV). The customer edge performs message interactions with a server via the AGGC and AGGV.
