Abstract: The invention relates to the technical field of agricultural planting, in particular to a controlled-release bacterial fertilizer for peanuts and a preparation method of the special controlled-release bacterial fertilizer. The special controlled-release bacterial fertilizer is composed of an inner layer and an outer layer; after the outer layer is released completely, the inner-layer network structure gradually absorbs water and preserves moisture, and has good slow release and controlled release properties, thereby achieving the gradual release of the inner layer, high fertilizer utilization rate, exerting the efficacy of the microbial agent and facilitating the large-area promotion.

Abstract: A display substrate, comprising a base substrate and a scan drive control circuit which is disposed in a non-display area of the base substrate. The scan drive control circuit comprises an input circuit, an output control circuit, and an output circuit. The output control circuit is connected to the input circuit and the output circuit. The output control circuit comprises a first node control capacitor and a second node control capacitor. The length of the first node control capacitor in a first direction LC1k, the length of the second node control capacitor in the first direction LC2k and the length of the scan drive control circuit in the first direction LY satisfy the following formula: L C ? 1 ? k L Y < L C ? 2 ? k L Y ; L C ? 1 ? k L Y < 0.2 .

Abstract: A bionic pectoral fin propelling device based on a planetary gear train, including a frame, a power source (1), a propelling part (2), left and right maneuvering parts (3), a fixed support plate (4), a movable support plate (5), a left pectoral fin (6), a right pectoral fin (7), a fish body (8), and a tail fin (9). The fixed support plate (4) and the movable support plate (5) are installed on the frame parallel to each other; the fixed support plate (4) is located in front of the movable support plate (5); and the left and right maneuvering parts (3) are located between the fixed support plate (4) and the movable support plate (5). The present invention solves the problem that the two pectoral fins are not synchronized, realizes variable speed propelling and left/right maneuvering, facilitates increasing the bearing capacity of the propelling device, and is particularly suitable in limited space applications.

Abstract: The described method and system provide an efficient routing of data packets protocol in an event-driven and delay-constrained WSN (wireless sensor network) that optimizes the sleep/wake schedule of nodes to maximize the lifetime of the WSM, subject to a constraint on the source-to-sink delay. Online forwarding techniques may be used to transfer data reports from monitoring nodes to the sink. A delay-constrained and energy-efficient routing protocol (DCEER) for asynchronous WSNs may be used to maximize the lifetime of the WSN while remaining within the maximum allowable delay requirements. With DCEER, each node may maintain the historical cost of forwarding a packet from itself to the sink as its virtual coordinate, and packets are forwarded in the direction of descending coordinates. The cost-based coordinates may change dynamically with a time-varying channel or topology.
