The invention belongs to the field of high-polymer materials, and discloses a preparing method of a full-cell polymer foaming material and the foaming material prepared through the method. The methodincludes the following steps of firstly, selecting a non-water-soluble thermoplastic polymer or a mixture of the non-water-soluble thermoplastic polymer and a water-soluble thermoplastic polymer to prepare a blank; secondly, coating the surface of the blank with a water solution of the water-soluble thermoplastic polymer to prepare a protection blank; thirdly, conducting supercritical fluid foaming on the protection blank to prepare a foaming blank; fourthly, conducting leaching and drying on the foaming blank to prepare the finished product. The size of cells in the surface of the prepared foaming material is 5-20 micron, and the cell density is not lower than 1.0*10<7> cell / cm<3>. Compared with the prior art, the surface porosity is high, the internal cell structure is not broken, and the material is free of pollution, environmentally friendly and low in production cost.

The invention discloses a production process of composite probiotics. The process comprises the following specific steps of: 1, breeding, namely (1) preparing a culture solution, and heating, dissolving and saccharifying the culture solution to obtain a saccharified solution; (2) sterilizing the saccharified solution at a high temperature, and cooling the sterilized saccharified solution to obtain a breeding culture medium; and (3) inoculating strains of lactic acid bacteria, bifidobacterium, bacillus subtilis and candida utilis into the breeding culture medium for culturing, thus obtaining four mature bacterium solutions; 2, fermentation, namely (1) mixing and sterilizing bean pulp and bran, thus obtaining a solid material; (2) respectively adding the four mature bacterium solutions into a diluent, thus obtaining four diluted bacterium solutions after diluting; and (3) respectively inoculating strains of the four diluted bacterium solutions into the solid material for fermentation, thus obtaining four fermented materials; and 3, drying and packaging, namely (1) mixing the four fermented materials and drying the mixed materials for the first time; (2) drying the mixed materials for the second time; (3) drying the mixed materials for the third time; and (4) crushing, outputting and packaging the dried materials to obtain the composite probiotics. The process can realize large-scale and continuous production and is suitable for industrial production.

The invention discloses a Th<4+> fluorescent identification material based on a 1,1'-bi-2-naphthol derivative and a preparation method and application of the fluorescent identification material. The preparation method includes the following steps: preparing an intermediate product (R)-2,2'-bis(methoxymethoxy)-1,1'-binaphthyl which is called RDB for short; preparing a target product 1-bis(3'-(2'-hydroxy-4'-(2'-hydroxy-1'-naphthyl)naphthyl))benzyl alcohol which is called RDB-B for short; preparing a complex of Th<4+> and the 1-bis(3'-(2'-hydroxy-4'-(2'-hydroxy-1'-naphthyl)naphthyl))benzyl alcohol; and preparing the Th<4+> fluorescent identification material based on the 1,1'-bi-2-naphthol derivative. The preparation method provided by the invention can synthesize the high-molecular polymericmaterial, the material can be reused, the internal structure is not damaged, and the problems that a small-molecular fluorescent material is easy to drop and cannot be reused are solved.

The invention relates to the technical field of agricultural machinery, in particular to a rubbing machine for medicinal materials. The rubbing machine is characterized in that a motor is fixed in the transverse middle of the front end of a lower layer of a frame, a motor shaft is connected with a driving transmission shaft through a pulley, a lower roller driving sprocket is connected with a lower roller driven sprocket arranged at the right end of a lower roller shaft through a belt, a driving guide gear meshes with a driven guide gear arranged on a driven transmission shaft over the driving transmission shaft in the vertical middle of the front of the frame, an upper roller driving sprocket arranged at the right end of the driven transmission shaft is connected with an upper roller shaft main sprocket through a chain. Upper and lower rollers with moderate sizes and moderate speeds rotate relatively, medicinal material can be effectively rubbed when passing between the upper and lower rollers, and the internal structure of the medicinal material is kept intact; a gap between the upper and lower rollers can be adjusted into a moderate rubbing gap by adjustment of a screw, and the medicinal material is never damaged by crushing or rubbing.

The invention provides a temporary power supply for a power distribution automatic terminal device. The temporary power supply comprises a device box, wherein a holder is arranged at the rear side of the upper part of the device box; a solar cell panel is hinged at the upper end of the holder; and a drive device for driving the solar cell panel is arranged between the holder and the solar cell panel. Through adoption of the technical scheme, according to the temporary power supply and the method, in a solar cell panel power supply mode, the influence resulting from a territory is very low, the normal working of a power supply terminal device is ensured under exceptional circumstances until line power-cut overhauling is carried out and factory maintenance personnel arrive. The increase of the line power-cut times and a terminal device offline rate resulting from singly processing device hidden troubles such as a PT device fault can be avoided, and the power supply reliability of the line is improved.
