This invention discloses a multi-layered tooth with a carious pulp chamber and its fabrication method. The method involves sequentially molding a simulated dentin crown with an upper pulp chamber, a simulated enamel with a caries-receiving groove covering the outer side of the simulated dentin crown, and a simulated caries portion within the caries-receiving groove through multiple in-mold injection molding processes. A simulated dentin root with a lower pulp chamber and simulated root canals is then formed by injection molding or 3D printing. The inner walls of the upper and lower pulp chambers and the simulated root canals are coated with simulated pulp dye. The simulated pulp is then placed into the lower pulp chamber and the simulated root canal. The simulated crown is then fixed to the upper end of the simulated dentin root by bonding or welding to form the simulated tooth. This invention's simulated tooth has a caries-like structure and reproduces the anatomical morphology of a real tooth, which helps improve students' clinical experience during practical training. The highly realistic tooth model of this invention can be used to explain different course content, improving teachers' teaching efficiency.

The application discloses instant flower glue with high elasticity and high glycosaminoglycan retention rate and a preparation method thereof. After cleaning and steaming of the flower glue, the flower glue is soaked in water below 20 DEG C, then mixed and dissolved with donkey-hide gelatin instant powder, milk and granulated sugar, sealed, filled and sterilized, and finally cooled by water cooling, with the cooling rate controlled within 10-15 DEG C / min, so that the center temperature of the product is steadily decreased to 25+ / -0.5 DEG C, and the instant flower glue is prepared. The instant flower glue prepared by the method has excellent texture characteristics, Q elastic and smooth, and does not stick to teeth. The flower glue has good water retention, and the proportion of free water is as high as 85% or more. Most importantly, the method maximally retains glycosaminoglycan in the flower glue, and the degradation of active ingredients such as chondroitin sulfate is reduced, and the dry base content is high.

This invention relates to the field of water treatment technology, specifically disclosing a hydraulically driven continuous flow aerobic granular sludge-membrane filtration integrated device and its application. The device includes an influent system, an effluent system, a reactor shell, a membrane module, and an aeration module. A first baffle is installed inside the reactor shell, dividing the interior into an anoxic zone and an aerobic zone. A multi-stage flow guiding mechanism is vertically arranged within the anoxic zone to change the flow direction of the sludge-water mixture. The aeration module is located at the bottom of the aerobic zone, enabling the sludge-water mixture to circulate between the anoxic and aerobic zones. The membrane module is located within the aerobic zone and positioned above the nano-aeration disc. This invention achieves favorable hydraulic conditions under continuous flow, creating a driving force for granulation and enabling rapid formation and stable operation of aerobic granular sludge. The combination of aerobic granular sludge and membrane module filtration improves effluent quality, reduces membrane fouling, shortens the process flow, and reduces floor space requirements.
