Abstract: Disclosed are apparatus, electronic device, and method for stitching dual-camera images. The method includes collecting two images having overlapping photographic content. The method includes extracting and matching feature points of the two images. The method includes roughly aligning the two images by using a homography matrix. The method includes accurately aligning the two images by using a least squares method to complete stitching the two images.

Abstract: Disclosed is a prefabricated laminated slab made in accordance with a pretensioning fibermesh anti-cracking process and a manufacturing method thereof, and belongs to the technical field of fabricated structure engineering. The prefabricated laminated slab comprises a concrete layer, fiber grids, distribution bars and truss bars. The fiber grids are subjected to prestress tensioning and pouring to form a novel laminated slab with the pretensioning process, an overall pouring process of layered formworks is adopted, the construction problem during prestress tensioning of the fiber grids of the component can be effectively solved, the crack resistance of the laminated slab can be improved by adopting the prestress grids, the rigidity is increased, and the crack width under normal use conditions is reduced.

Abstract: An atomizing liquid gel with reversible phase transition characteristics includes: a sugar-based gelling agent, 0.1-3.0 wt %; an atomizing liquid, 97.0-99.9 wt %; a molecule of the sugar-based gelling agent is a sugar molecule introduced with an amide group and/or an aryl group, and the sugar molecule optionally further includes at least one hydrophobic structural part selected from —CxHy, —O—CxHy and and x>2 and y>2. The atomizing liquid gel has characteristics of thermal reversible phase transition and/or shear reversible phase transition, a temperature of gel-sol phase transition is 100° C.-248° C., and a critical shear stress of the gel-sol phase transition is 40-800 Pa. Under heating and/or oscillation, the atomizing liquid gel converts from the gel state to a sol state, and the atomizing agent fixed in the gel releases to form an inhalable aerosol.

Under heating and/or oscillation, the atomizing liquid gel converts from the gel state to a sol state, when the heating and/or oscillation are stopped, the atomizing liquid gel is quickly recovered from the sol state to the gel state.

Abstract: A variable-frequency surface acoustic wave electronic cigarette includes an atomizer. An atomization cavity is disposed in the atomizer, and a variable-frequency surface acoustic wave atomization chip is disposed at a lower portion of the atomization cavity. An inverted trapezoidal interdigital transducer is disposed on the variable-frequency surface acoustic wave atomization chip. An e-liquid storage cavity is disposed in the atomization cavity. A porous ceramic sheet is disposed between the e-liquid storage cavity and the atomization chip. The new variable-frequency surface acoustic wave electronic cigarette can realize any adjustment of the working frequency within a set range, thereby realizing the autonomous regulation and control of a smoke particle size after atomization of the e-liquid.
