The invention relates to the technical field of automobile seats, and provides an automobile seat partition rapid temperature control and fatigue awakening device and method. The device sequentially comprises a coating layer, a flexible soaking layer, a thermoelectric module array, a micro-channel liquid cooling plate, a heat insulation supporting layer, a sponge substrate, a pressure sensor array, a temperature sensor array, a control unit, a liquid cooling circulating pump and an air conditioner heat exchanger. The thermoelectric module array at least comprises two semiconductor thermoelectric modules which are respectively arranged in the cushion area and the neck area; the control unit controls the corresponding semiconductor thermoelectric module and the liquid cooling circulating pump to perform top-speed heating or top-speed cooling; and when a fatigue state signal of the vehicle-mounted DMS system is received, the semiconductor thermoelectric module at the neck is controlled to output high-frequency pulse current so as to generate rapid temperature difference jump. The thermoelectric module is coupled with an air conditioner liquid cooling loop through the micro-channel liquid cooling plate, the heat dissipation bottleneck of a traditional semiconductor seat is solved, and dynamic temperature control of each partition is achieved by generating a body pressure cloud picture.

The application belongs to the field of food preservation technology, and relates to a chitosan-gelatin composite preservative solution based on plasma-activated water modification and a preparation method and application thereof. First, PAW is used to prepare chitosan solution and gelatin solution respectively, and the composite preservative solution is obtained after mixing and homogenizing. The coating is dehydrated to form a preservative film. The PAW is prepared by treating deionized water with low-temperature plasma, and is rich in active ingredients such as hydroxyl radicals and hydrogen peroxide, which can effectively modify chitosan and gelatin, enhance intermolecular crosslinking, and form a composite film with a dense network structure. The composite film can be applied to fish preservation through coating or immersion, can effectively inhibit the growth of microorganisms, and can improve the color of fish fillets. In addition, the composite film has the function of delaying protein degradation by inhibiting endogenous protease activity, thereby maintaining the muscle tissue structure and prolonging the shelf life of chilled fish fillets. The application has the advantages of simple process, green safety, remarkable preservation effect, and wide market application prospect.

This invention discloses a method for preparing N-doped β"-AlON solid electrolyte powder, which includes the following steps: (1) Slurry preparation: weigh anhydrous ethanol and dispersant, add the dispersant to anhydrous ethanol and stir evenly to obtain a mixed solution, then weigh aluminum source powder, lithium source powder, sodium source powder and nitrogen source powder to obtain a mixed powder, add the mixed powder to the mixed solution and stir thoroughly until the mixture is evenly mixed to obtain a mixed slurry; (2) Grinding to prepare precursor slurry: grind the mixed slurry thoroughly to obtain a precursor slurry; (3) Spray drying: spray dry the wet-ground precursor slurry to obtain spray-dried powder; (4) Calcination: calcine the spray-dried powder in a nitrogen atmosphere, and keep warm after calcination to obtain N-doped β"-AlON powder.

This invention discloses a high-functionality defatted rice bran, its preparation method, and its applications. The method includes: stabilizing fresh rice bran with saturated steam to inactivate lipase, obtaining stabilized rice bran; then using the stabilized rice bran as raw material, extracting and defatting it with supercritical CO2 to separate rice bran oil and high-functionality defatted rice bran.
