The invention discloses a yam fish ball and a production method thereof. The yam fish ball comprises the following components by weight part: 10 parts of fish mixture, 1-4 parts of Chinese yam rhizome, 0.2-0.4 part of egg white, 0.2-0.6 part of potato starch, 0.2-0.4 part of fat lining, 0.73-0.83 part of modifier and 0.5 part of seasoning. The method comprises the following steps: (1) selecting fresh water fish; (2) poaching, draining, rubbing and straining fish meat; (3) preparing yam mash; (4) mincing the fish meat and producing balls; (5) gelling the yam fish balls; and (6) packaging, quickfreezing and refrigerating. The yam fish ball produced by the method has low cost, full nutrition, delicious taste, white colour and good sense, is easy for digestive absorption and is favorable forhealth of human bodies.

The invention relates to a target voice privacy protection method and a target voice privacy protection system. The method comprises the following steps of: generating an interference voice signal based on a target voice signal, and combining the existing interference signals in an interference repository to synthesize composite interference sound, wherein the target sound and the composite interference sound are played by loudspeaker systems at different positions in a room. In the system, the interference voice signal is generated on the basis of the target voice signal, and the existing interference signals in the interference repository are combined to synthesize the composite interference sound, wherein the target sound and the composite interference sound are played by the loudspeaker systems at different positions in the room. The interference sound is a composite interference signal comprising a target voice signal-related part, wherein the related part is generated by processing the target voice signal, and the interference sound has the advantages of high interference efficiency and low annoyance. In addition, the interference sound and the target sound are played by the loudspeaker systems at different positions in the room, a sound signal is picked from interference voice recording equipment, and normal operation of a conference is not influenced basically.

The invention relates to photo-thermal dual-curing shielding glue and a preparation method thereof, and belongs to the technical field of chemical materials. The photo-thermal dual-curing shielding glue is mainly prepared from, by weight, 40-70 parts of low polymer, 30-60 parts of activated monomer, 2-8 parts of photo-initiators, 1-5 parts of thermal initiators, 0.1-4 parts of toners and 0.1-10 parts of auxiliaries. The low polymer is at least one of epoxy acrylate, pure acrylic ester and polyester acrylate, and the activated monomer is at least one of mono-functional acrylic ester, bifunctional acrylic ester and poly-functional acrylic ester. The shielding glue can adopt a photo-thermal dual-curing mode, UV (ultraviolet) pre-curing shaping is performed, complete heating and curing are performed, and batch treatment is performed within a certain proper time. The shortcomings of serious excessive glue caused by only heating and curing or normal-temperature curing and incompleteness of only UV curing are overcome. The photo-thermal dual-curing shielding glue can be widely used for touch glass, LCD (liquid crystal display) modules and cover glass shading and enhancement.

The invention relates to a back-passivation efficient PERL battery technology. The back-passivation efficient PERL battery technology comprises the steps that a silicon wafer is cleaned in a HF / HNO3 mixed solution, a surface damaged layer is removed, double-side polishing is carried out, a SiOx film layer is deposited on a single-side, a suede face is made, POCl3 single-side deposition and diffusion are carried out in a high-temperature furnace, surface phosphorosilicate glass is removed, SiNx with a thickness of 80 nm is deposited on the front side of the silicon wafer, SiOx with a thickness ranging from 10 nm to 20 nm is deposited on the back side of a polished surface of the silicon wafer, an SiNx layer with a thickness ranging from 100 nm to 200 nm is deposited in a pipe-type or a plate-type PECVD equipment, slots and holes are formed in a back-passivation layer, and silk-screen printing and sintering are carried out on back aluminium paste, a back electrode and a positive electrode. Compared with the prior art, the technology is simplified, and therefore the large-scale mass production is facilitated.

The invention relates to the technical field of leatherworking, and particularly relates to a production technology for preparing leather from pig split leather scytoblastema. The production technology comprises the following working steps: selecting materials, spraying and filling resin, scraping and repairing, drying, flattening, rubbing down, spraying a covering coating, and pressing by plates. According to the production technology disclosed by the invention, the loose side parts on the pig split leather scytoblastema is sprayed and filled with the resin, then the irregular parts on the surface of the scytoblastema are scraped in a scraping and repairing manner, then the surface of the scytoblastema of the pig split leather is smoothened and flattened by drying, flattening, rubbing down, spraying the covering coating and pressing by the plates, so that the quality of the prepared leather can reach the level of cowhide and the added value of the leather can be improved.
