Abstract: Disclosed is a secret-key provisioning (SKP) method and device based on an optical line terminal (OLT), which can generate an SKP queue according to key requests received; generate at least one secret-key according to the SKP queue; and store the at least one secret-key in key pools (KPs) of corresponding ONUS. A non-transitory computer-readable storage medium is also disclosed.

Abstract: An electrode plate, an electrode assembly, and a secondary battery are provided. The electrode plate includes a current collector, an active material layer arranged on one surface of the current collector, and an electrical connection member electrically connected to the current collector. The active material layer is arranged on a main body portion of the current collector, the electrical connection member and the current collector are connected to each other by welding at an edge of the current collector, the welding connection region is referred to as a transfer welding region, and the current collector includes a support layer and an electrically conductive layer arranged on one surface of the support layer. The electrode plate further includes a first insulation layer arranged on a further surface of the current collector and covering at least the entirety of the transfer welding region when viewed in a thickness direction of the electrode plate.

Abstract: A method of preparing a flavor composition containing D-allulose includes: (1) weighing D-allulose, mogroside, steviol glycoside and trichlorosucrose in parts by weight, and mixing them evenly to obtain a mixed powder; (2) degassing, compressing, and rolling the mixed powder, and extruding the raw materials into flakes; and (3) crushing and granulating the shaped flakes to obtain the flavor composition. D-allulose is used as the main raw material, and added high-intensity sweeteners as auxiliary raw materials. After the raw materials are mixed evenly, dry granulation is adopted, and the powder is degassed and pre-compressed by using the crystal water in the raw materials, and squeezed by a hydraulic roller to form a bonding force between the various sweetener molecules to form flakes, and the flakes are processed by processes such as crushing and granulating to obtain the flavor composition granules containing D-allulose with the various sweeteners integrated uniformly as a whole.

Abstract: Disclosed is a control device for adhesion and detachment, including a base, an actuator, and a movement mechanism including a bearing unit, a peeling unit, and an adhesion unit. The peeling unit is a thin sheet with a high elastic modulus and has a first side and a second side that are opposite to each other. An upper surface of the peeling unit is fixed on a lower surface of the bearing unit. The actuator is fixed to the first side of the peeling unit. The adhesion unit is arranged on a lower surface of the peeling unit. The peeling unit bends and elastically deforms from the first side towards the second side under an action of the actuator in such a manner that the adhesion unit moves synchronously. The peeling unit is in a flat state upon a recovery from the elastic deformation.

Abstract: A method for vacuum smelting and variable pressure solidification forming aluminum alloy piece with ultra-thin wall and high gas tightness is provided, in which an induction heating furnace is set in a vacuum tank, a quartz crucible with thickness of 5˜8 mm is used; a preheated aluminum alloy ingot is placed in the crucible, side doors of the tank is closed, and a vacuuming processing is performed for the tank; the melt is filled from the bottom layer of the casting; when the melt reaches to the top, the main valve and the air-release valve are turned on until the inside and outside pressures are consistent, and then the casting is taken out. The requirement of high air tightness for vacuum tank is reduced, and aluminum alloy casting with high quality can be obtained at lower cost.

Abstract: The present invention relates to an electrochemical method for continuously producing a pure-oxygen gas and an oxygen-lean gas from an oxygen-containing gas mixture. At least two water electrolyzer units and two power supply units are used, of which each former solely corresponds to each latter, respectively. The two power supply units are at least one power supply unit of recycling hydrogen energy and an externally-connected power supply unit. The power supply unit of recycling hydrogen energy consists of hydrogen fuel cells, and the externally-connected power supply unit is comprised of at least one of the following cells and/or power supply, e.g. (a) solar cell(s), (a) direct methanol fuel cell(s), and/or an AC grid. In terms of the electrical circuit, each power supply unit is solely connected with the corresponding water electrolyzer unit.
