Abstract: Provided are a method and a device for acquiring a temperature and a computer-readable storage medium. The method for acquiring a temperature includes: building a temperature acquisition model, wherein the temperature acquisition model is configured to acquire, based on an operating parameter of the radioactive substance treatment system input to the temperature acquisition model, a temperature of different parts of the radioactive reactant in the radioactive substance treatment system under a condition of the parameter; inputting a current operating parameter of the radioactive substance treatment system into the temperature acquisition model during the treatment for the radioactive substance; and acquiring a current temperature of different parts of the radioactive reactant in the radioactive substance treatment system output by the temperature acquisition model.

Abstract: Provided are a bovine rotavirus fusion protein and calf diarrhea multivalent vaccine. The bovine rotavirus fusion protein contains a VP6 fragment, wherein the VP6 fragment contains an amino acid sequence as represented by SEQ ID NO. 4, and at least one loop region of the following (a)˜(c) is substituted with an antigenic epitope derived from bovine coronavirus and/or an antigenic epitope derived from E. coli: (a) amino acid residues of sites 168-177; with an amino acid sequence as represented by SEQ ID NO. 1; (b) amino acid residues of sites 194-205; with an amino acid sequence as represented by SEQ ID NO. 2; and (a) amino acid residues of sites 296-316, with an amino acid sequence as represented by SEQ ID NO. 3, The bovine rotavirus fusion protein contains a plurality of antigenic epitopes, and can enable a host to generate a plurality of antibodies after immunizing the host.

Abstract: Embodiments of the present application relate to polymers used as polymeric polyvalent hubs for liquid phase oligonucleotide synthesis. Methods for making an oligonucleotide by liquid phase oligonucleotide synthesis using the polymers are also provided.

Abstract: A method for deep treatment of household waste leachate by a biochemical process is provided, including: arranging one anoxic tank and two aerobic tanks in series; introducing the household waste leachate into the primary anoxic reactor, and diluting the household waste leachate to an concentration acceptable to microorganisms; introducing the diluted household waste leachate into the primary aerobic reactor, and subjecting the diluted household waste leachate to an pre-nitrification reaction to obtain a reactant; introducing the reactant into the secondary aerobic reactor, and subjecting the reactant to a main nitrification reaction to convert ammonia nitrogen into nitrate nitrogen and nitrite nitrogen by nitrification of nitrobacteria; refluxing the nitrification liquid to the primary anoxic reactor, converting the nitrate nitrogen and nitrite nitrogen into nitrogen gas by denitrobacteria in the primary anoxic reactor, and discharging the nitrogen gas into atmosphere, thereby finishing an denitrification pr
