Abstract: The present invention discloses a method of constructing a solid slippery surface, belonging to the technical field of preparation of lubricating materials. The method of constructing a solid slippery surface comprises (1) constructing a metal oxide coating on the surface of a metal substrate by anodic oxidation, and then modifying the metal oxide coating using a low surface energy material to afford a superhydrophobic coating; and (2) fulling mixing photothermal nanoparticles and solid paraffin, followed by infusing the mixture onto the surface of the superhydrophobic coating to afford the solid slippery surface. The preparation method of the present invention is performed in a simple process and is environmentally friendly. The solid slippery surface constructed in the present invention has excellent photothermal and anti-icing performance, making some improvements in the field of copper metal anti-icing.

Abstract: A method and an apparatus for displaying an information flow on a terminal device, an electronic device, a computer-readable storage medium, and a computer program product are provided. An implementation is: in response to detecting an activation operation on an application for displaying the information flow, reproducing, on the terminal device, a first page displayed on the terminal device when the application is last switched to running in the background or closed; and in response to determining that a time interval between the activation operation and the application being last switched to running in the background or closed does not exceed a first threshold, displaying a second page as a continuation of a content entry displayed in the first page, where the second page includes at least one first content entry cached in the terminal device before the activation operation but not displayed in the first page.
