Abstract: The present invention provides a method for the co-production of 1,1-difluoroethane and vinyl chloride, including: (a) vaporizing dichloroethane and hydrogen fluoride, and delivering the vaporized dichloroethane and hydrogen fluoride into a reactor for a catalytic reaction under the action of a catalyst to obtain a reaction product; (b) delivering the reaction product into a first rectifying tower for separation to obtain an overhead product from the first rectifying tower and a bottom product from the first rectifying tower; (c) delivering the overhead product from the first rectifying tower into a second rectifying tower for separation to obtain hydrogen chloride and a bottom product from the second rectifying tower; (d) delivering the bottom product from the second rectifying tower into a purifying tower for purification to obtain an overhead product from the purifying tower; (e) simultaneously delivering the overhead product from the purifying tower and a saturated organic solvent into a third rectifying

Abstract: A display method, an electronic device and a storage medium. A particular implementation of the method includes: determining eye position information of an object in an image; determining camera position information of naked eye 3D according to the eye position information; creating an eye space according to the camera position information; obtaining, according to object position information of a target object in the eye space, projection position information of the target object on a projection plane based on projection information; and displaying the target object according to the projection position information.
