Abstract: Embodiments of the present disclosure relate to the technical field of batteries, and in particular to a battery cell and a battery. The battery cell is formed by winding a first electrode sheet and a second electrode sheet; the first electrode sheet and the second electrode sheet are separated by a separator; a head portion of the second electrode sheet is provided with an empty foil area which is not coated with an active substance; the empty foil area is provided with a first protection adhesive paper and second protection adhesive paper; the first protection adhesive paper and the second protection adhesive paper are located on two sides of an edge of a head portion of the first electrode sheet in a thickness direction of the battery cell.

Abstract: A response system and method for an integrated wind-solar-storage electric vehicle charging station during a thunderstorm are provided. Thunderstorm information of a region in which an integrated wind-solar-storage electric vehicle charging station and its power supply line are located is analyzed, and a tripping possibility of the power supply line of the integrated wind-solar-storage electric vehicle charging station is determined. Important electrical loads of the charging station and its power supply line are classified and counted. A demand response capability of the charging station is calculated, and a corresponding quantity of important loads are matched. When the power supply line trips, a location and an isolation status of a line fault point and power transmission waiting duration are determined, and the matched important load is adjusted accordingly. The charging station is enabled to participate in a demand response in the event of a thunderstorm and line tripping.

Abstract: Provided is a fermentation fungal substance of Astragalus membranaceus/Paecilomyces cicadae and its use. The fermentation fungal substance is obtained by solid fermentation with Astragalus membranaceus powder as a fermentation substrate and Paecilomyces cicadae as a fermentation strain. The fermentation fungal substance of Astragalus membranaceus/Paecilomyces cicadae in the present disclosure plays a significant role in treating hyperuricemia and/or hypertriglyceridemia.

Abstract: A multi-user uplink and downlink beam alignment method for asymmetric millimeter wave large-scale MIMO includes constructing an all-digital multi-directional beam for multiple-direction probing; performing multiple rounds of downlink beam training from the base station to the UE; controlling the UE to perform a beam decision according to the receiving signals, and determining a target downlink sending-receiving beam pair; performing data processing on the receiving signals to generate training data for predicting an uplink sending narrow beam, and performing training on a preset neural network; performing online real-time signal detection based on the trained network parameters and the receiving signals to predict a target uplink sending narrow beam; and controlling the UE to feedback an index of a target downlink sending narrow beam to the base station, and widening the target downlink sending narrow beam into a target uplink receiving beam according to the feedback index.

Abstract: A sample preparation mould and a sample preparation method for the triaxial test of MSW are provided. In the present invention, the cylindrical main mould comprises two curved steel pieces, and the two sides of each curved steel piece have a stretched connection part; the two curved steel pieces are connected with each other and clamped by two steel clamps; porous stones are arranged at two ends of the cylindrical main mould and fixed separately by a top limiting lantern ring and a bottom lantern ring; the top limiting lantern ring is detachably connected to the top hopper, from which MSW materials are input; the cylindrical main mould is radially constrained in four positions, and the two ends thereof are axially constrained, thereby significantly improving stability during compacting and hence ensuring the axial and radial sizes of the MSW sample.

Abstract: A safety gate for selectively covering socket holes of an electrical outlet comprises an upper slide plate comprising an upper space with an upper recessed platform on a first side and an upper slant on an opposed side. A lower slide plate comprises a lower space with a lower slant on a first side and a lower recessed platform on an opposed side. The upper and lower spaces allow load plug pins to pass through, and the intervals of the spaces correspond to the interval of load plug pins. The upper slide plate is stacked with the lower slide plate to overlap the upper recessed platform with the lower slant and the upper slant with the lower recessed platform. The upper slide plate slides relative to the lower slide plate. Load plug pins slide along the inclined slopes of the upper and lower slants to slidingly displace the upper and lower slide plates a distance that is no less than the thickness of a pin.
