Abstract: The present disclosure relates to a rotary transition section and a tempering and forming apparatus for forming bent glass. The rotary transition section includes a main rack and an auxiliary rack. A plurality of flexible shaft rollers for forming glass are arranged at intervals on the auxiliary rack along the glass conveying direction. An end of the auxiliary rack that is closer to a heating furnace is rotatably connected to the main rack. An end of the auxiliary rack that is away from the heating furnace is connected to a traction mechanism arranged on the main rack. In the tempering and forming apparatus employing the rotary transition section, a forming and tempering section has a lifting function to achieve abutment against a roller surface after the rotation of the transition section, which in turn solves the technical problem that the edge of the glass is difficult to form.

Abstract: A method for bending and tempering of curved glass using flexible shafts is provided. During production of curved glass, after discharged from a heating furnace, glass is preformed with the two edge portions of the glass in the transverse direction being kept in the same plane and the middle portion of the glass in the transverse direction gradually sinks along the conveying direction. The glass then enters a forming and tempering section with the two edge portions in the transverse direction being supported and is finally formed and tempered. In this method, when the glass gradually becomes curved and enters the forming and tempering section, the two edge portions of the glass in the transverse direction are always supported by flexible shaft roller beds, thereby preventing the edge portions from being dangled and avoiding the formation of wavy edge portions.

Abstract: A paramyxovirus vaccine strain for novel coronavirus pneumonia and a construction method thereof are provided. The method includes performing a recombination of N and F genes of Newcastle disease virus type VII of Paramyxoviridae with P, M, H, L genes of Canine distemper virus of Paramyxoviridae to obtain a recombinant virus, inserting S1 gene of the novel coronavirus between the P and M genes of the recombinant virus to obtain a recombinant vector. The vaccine strain constructed can stably and efficiently express the novel coronavirus S1 protein, and induce the body to produce antibodies; and the recombined virus vaccine strain can stimulate the human body to produce mucosal immunity, and the prepared vaccine can be vaccinated through a nasal spray. Moreover, the vaccine strain can be tested in poultry and dogs, saving time, reducing costs, and being more conducive to actual production due to large output.

Abstract: A display substrate and a method thereof, a display panel and a display device are provided. The display substrate includes: a base substrate; and at least one first signal line and a first insulating layer which are disposed on the base substrate; a surface of the first insulating layer away from the base substrate and a surface of the at least one first signal line away from the base substrate are parallel with the base substrate and are substantially located in a continuous flat plane. The first insulating layer which is disposed side by side with the first signal line can improve the surface flatness level of the display substrate and prevent the subsequently formed structures on the display substrate suffering from display defectives due to a too large step.
