The invention discloses a rectal in-situ gel for antipyretic and a preparation method thereof, which comprises the following components in terms of mass fraction: 1-20% of antipyretic drug, and 5-30% of in-situ gel matrix , 0.1-10% of tackifier, 0.1-10% of lubricant, 0.1-10% of preservative, 0.1-10% of transdermal absorption regulator, and the balance is water. The rectal in-situ gel for antipyretic provided by the present invention not only has no drug dead angle, but also enhances the adsorption capacity and prolongs the drug effect by adding bioadhesive substances, and reduces the excretion of the drug caused by the stool caused by the solid preparation; it has good Inclusiveness, it can be either a specific medicinal ingredient or an active ingredient of a traditional Chinese medicine extract.

The invention relates to an alloy for recovering a polyethylene glycol terephthalate / acrylonitrile-butadiene-styrene copolymer and a preparation method thereof. The method comprises the following steps of: recovering 60-90% of PET (Polyethylene glycol Terephthalate), 2-30% of ABS (Acrylonitrile Butadiene Styrene) resin, 3-30% of an enhancer, 1-5% of a compatilizer, 0.1-0.5% of an antioxygen, 0.1-0.5% of rare-earth metal salt, 0.1-2% of a molecular weight modifier and 0-2% of other assistants in percentage by weight; uniformly mixing by a high speed mixer; adding into an extruder to obtain material strips, wherein the processing temperatures of the extruder from a feed inlet to a grinding mouth are sequentially 180 DEG C, 185 DEG C, 190 DEG C, 195 DEG C, 200 DEG C, 205 DEG C, 210 DEG C and 215 DEG C, and the rotating speed of a main machine of the extruder is 80-120r / min; and carrying out water cooling and dicing on the material strips to obtain the modified aggregates. Compared with the prior art, the alloy provided by the invention has the advantages of industrial production in batches, excellent tensile strength, high impact strength, mobility, chemical stability and the like.

The invention provides an imidazole sulfonate ionic liquid flame retardant containing a DOPO structure. The chemical structure of the flame retardant is as shown in formula , wherein X is alkyl, phenyl or DOPO group; Y is alkyl, vinyl, phenyl or p-methylphenyl. The invention further provides a preparation method of the flame retardant and application of the flame retardant in the preparation offlame-retardant materials. The ionic liquid flame retardant is simple in preparation method, free of halogen, wide in raw material source, low in cost, excellent in flame retardance to epoxy resin, low in adding amount, good in compatibility with the epoxy resin, low in influence on the mechanical performance of the epoxy resin, and the like.

The invention discloses a text classification model construction method and device and a text classification method and device, and the method comprises the steps: obtaining training text data and a plurality of pieces of preset label attribute information corresponding to a field to which the training text data belongs; inputting the training text data and a plurality of pieces of preset label attribute information into a reading understanding model to obtain text interaction representation between each piece of training text data and each piece of preset label attribute information; inputting each text interaction representation into the feature extraction model to obtain text key features; inputting the text key features into an initial classification model for classification and identification to obtain a probability value of each piece of training text data belonging to each piece of preset label attribute information, and obtaining a classification result according to the probability value; and training model parameters of the initial classification model according to a classification result until a loss function value of the initial classification model meets a target condition to obtain a target text classification model.

The invention relates to a preparing method for electrostatic type air purifier dust collecting plates. The preparing method comprises the steps that 1, polypropylene plastic plates are subjected to surface oxidation processing through a potassium permanganate / sulfuric acid solution, and then acid pickling, deionized water cleaning and stoving are conducted; 2, the polypropylene plastic plates are immersed into an aniline solution and a hydrochloric acid solution for processing for 10-30 min and dropwise added with an ammonium persulfate solution under the stirring condition with the temperature being 5-15 DEG C, and the stirring reaction lasts for 18-30 hours; the polypropylene plastic plates are taken out, cleaned and dried in the air at the room temperature, and polypropylene plastic plates with a conductive material on the surfaces are obtained; and 3, the obtained polypropylene plastic plates are overlapped in an up-down mode and arranged in the direction of the conductive material in a staggered mode, and the two ends of each polypropylene plastic plate are connected through conducting wires or conductive plates. The preparing method for the electrostatic type air purifier dust collecting plates is mild in condition, safe and environmental friendly, adopted polyaniline is used as the conductive material on the surfaces of the plastic plates, the cost is low, and safety and environmental protection are achieved; the dust collecting plates are good in dust collecting effect and long in service life, and the electrostatic dust collecting plates can play a role in an air purifier effectively.
