Abstract: The embodiment of the present disclosure provides a method and a device for fine reconstruction of a sedimentation structure of a flume. The device includes: a combined bottom plate and a combined freezing flume, wherein the combined bottom plate is formed by tiling and splicing a plurality of equal-thickness and rectangular basic bottom plates, a splicing gap is located between adjacent basic bottom plates, the splicing gap is filled with elastic adhesive, and the filled splicing gap is as thick as the basic bottom plates; the combined freezing flume includes a plurality of local freezing flumes; and each of the basic bottom plates has a local freezing flume that matches the basic bottom plate.

Abstract: A displaying base plate and a manufacturing method thereof, and a displaying device. The displaying base plate includes a substrate, and a first electrode layer disposed on one side of the substrate, wherein the first electrode layer includes a first electrode pattern; a first planarization layer disposed on one side of the first electrode layer that is away from the substrate, wherein the first planarization layer is provided with a through hole, and the through hole penetrates the first planarization layer, to expose the first electrode pattern; and a second electrode layer, a second planarization layer and a third electrode layer that are disposed in stack on one side of the first planarization layer that is away from the substrate, wherein the second electrode layer is disposed closer to the substrate, the second electrode layer is connected to the first electrode pattern and the third electrode layer.
