The invention discloses a method for establishing a canine distemper sensitive cell line based on a Nectin4 receptor. The method comprises the following steps: (1) extracting total RNA of a sample andsynthesizing cDNA; (2) amplifying and cloning Nectin4; (3) modifying Nectin4; (4) connecting and converting dNectin4-Hatag and extracting recombinant plasmid; (5) packaging recombinant slow virus; abd (6) transfecting cells and screening positive cell line. The Vero-Nectin4 established according to the method disclosed by the invention can stably express the Nectin4 receptor and is high in universality; the CDV virulent strain is capable of growing in the cell line and acquiring obvious CPE lesion; and the method is suitable for wide application in culturing or separating the canine distempervirus.

The invention discloses a production process of a degradable lunchbox. The production process includes the steps of firstly, preparing master batch and auxiliary materials, wherein the master batch comprises chaff, straw and sugar residues according to the weight ratio of (1-1.5):(11-1.5):(0.6-1), and the auxiliary materials comprise lithopone, adhesive, coagulant such as alum, and waterproofing agent according to the weight ratio of (3-3.5):(2-2.5):(0.5-0.7):(0.4-0.6); secondly, casting a mould under 200-220 DEG C after material cutting; thirdly, applying the adhesive, and baking under 90-100 DEG C for 9-10 minutes to obtain the degradable lunchbox. The production process has the advantages that the degradable lunchbox produced by the production process is a disposable degradable lunchbox produced by raw materials conforming to national food sanitation and environment standards and is nontoxic, harmless, clean and free of pollution, environmentally friendly, easy to recycle and treat, easy in absorption and capable of being easily absorbed by natural environments.

The invention relates to the technical field of grain boundary diffusion type neodymium iron boron component analysis, and discloses a component analysis sample preparation method of grain boundary diffusion type neodymium iron boron, which comprises the following steps of S1, neodymium iron boron pretreatment, S2, grain boundary diffusion type neodymium iron boron preparation, S3, grain boundarydiffusion type neodymium iron boron selection, S4, cleaning and drying, S5, sample crushing, and S6, sample analysis and sample preparation. According to the component analysis and sample preparationmethod of the grain boundary diffusion type neodymium iron boron, component analysis and sample preparation are conducted on the grain boundary diffusion type neodymium iron boron through six steps ofS1, neodymium iron boron pretreatment, S2, grain boundary diffusion type neodymium iron boron preparation, S3, grain boundary diffusion type neodymium iron boron selection, S4, cleaning and drying, S5, sample crushing and S6, sample analysis and sample preparation, the step process is simple, and operation is easy. Meanwhile, the flaky sample is converted into powder in the step S5, digestion treatment in the step S6 is facilitated, the sample digestion process is more sufficient, the time is shorter, and the component analysis and sample preparation time is greatly shortened.
