The application discloses a contact type regenerative combustor based on pure ammonia catalysis and a thermoelectric conversion system thereof, and the device comprises a body surrounded by an upper wall surface, a lower wall surface and a side wall surface, and the body is provided with a plurality of splitter plates and a tail gas baffle; the inner surfaces of the upper wall surface and the lower wall surface are coated with a perovskite catalyst layer; the outer sides of the upper wall surface and the lower wall surface are directly attached with thermoelectric modules, and the outer sides of the thermoelectric modules are provided with cooling plates. The application optimizes the flow field and enhances the disturbance through the splitter plates, guides the tail gas to preheat the mixed gas by using the baffle, and reduces the reaction activation energy by using the catalyst to assist combustion; the high-temperature tail gas directly heats the hot end of the thermoelectric module, and the liquid cooling plate maintains the low temperature of the cold end, thereby forming efficient thermoelectric conversion. The application has the advantages of compact structure, high thermal efficiency, effectively widened stable working range of ammonia combustion, and solved problems of small temperature difference, low efficiency and poor combustion stability of ammonia fuel of the existing combustor thermoelectric system.

The present application relates to the technical field of intelligent measurement, engineering surveying and mapping and three-dimensional digital modeling, and particularly relates to a high-precision controllable three-dimensional scanning site optimization method based on a genetic algorithm: the genetic algorithm is used to optimize the layout of three-dimensional scanning sites, and a high-precision, self-adaptive and efficient scanning scheme is realized. Compared with the traditional uniform station distribution method or the experience-based site selection method, the present method can dynamically adjust the sites according to the given error requirement, ensure the measurement accuracy, optimize the number of sites, improve the scanning efficiency and data integrity. Intelligent optimization calculation reduces manual intervention, improves the automation level of surveying and mapping, and can be widely applied to high-precision measurement of complex structures such as bridges, prefabricated buildings, steel structures and the like, and has high engineering popularization value and application prospect.

The application discloses application of monardocin in preparation of a drug for treating thymus injury, and finds through cell experiments and animal experiments that the monardocin can be used for relieving acute thymus injury, regulating secretion of inflammatory factors in thymus epithelial cells and subgroups thereof, and can increase the number of immune cells, especially can significantly increase the number of thymus cells and cells in each subgroup in sepsis newborn mice, the number of cells in each subgroup of thymus epithelial cells, and the number of T lymphocytes and cells in each subgroup of the spleen. The application first proves that the natural product monardocin can relieve acute thymus atrophy in sepsis newborn mice, thereby improving the immunity of the body, and provides a brand-new natural drug intervention strategy for acute thymus injury induced by sepsis.

This invention belongs to the field of injection molding adhesive technology, specifically relating to an anti-seepage composite admixture, anti-seepage reinforced concrete for drainage pipes, and their preparation method. The composite admixture comprises the following raw materials in parts by weight: 1 part modified aliphatic sulfonate water-reducing agent, 0.15-0.25 parts lignin sulfonate water-reducing agent, and 0.8-1.2 parts expanding agent. The modified aliphatic sulfonate water-reducing agent is prepared by: preparing an emulsion using unsaturated acid anhydride, C14-C18 alkyl acrylate monomer, and emulsifier; simultaneously, preparing an initiator solution for later use; under an inert atmosphere, adding sulfites, formaldehyde (part 1), and water to a reaction vessel, raising the temperature, adjusting the pH, and controlling the temperature to add ketones and formaldehyde (part 2); adding formaldehyde (part 3), simultaneously adding the emulsion and initiator solution, and gradually increasing the temperature during the reaction. The modified aliphatic sulfonate water-reducing agent can stabilize small, closed bubbles, forming a uniformly distributed microbubble system. The three components in the composite admixture synergistically optimize the size, quantity, and distribution of bubbles.
