Abstract: A visible-light-photocatalyzed composite light-transmitting concrete contains several bundles of optical fibers, the optical fibers are coated with a protective layer on their outer surface, the protective layer contains a visible light photocatalyst, and the concrete has several gas-permeable pores. Such concrete is prepared by mixing a visible light photocatalyst and a light-transmitting glue, applying the mixture to the surface of optical fibers to form a protective layer, and using optical fibers in the concrete. The resulting concrete has dual properties of light transmittance and photocatalytic oxidation of gas-phase pollutants under visible light irradiation. The visible-light-photocatalyzed composite light-transmitting concrete significantly breaks through the limitation of photocatalytic concrete to light sources, so that gas-phase pollutants can be removed under visible light irradiation through photocatalysis of light-transmitting concrete.

Abstract: This application relates to an application interface processing method performed at a terminal. After running a parent application on an operating system, the terminal generates, by the parent application, a common interface container by using a common resource of a plurality of child application interfaces. In response to an event of launching a first child application interface, the terminal loads an independent resource of the first child application interface in the common interface container, the independent resource including data in the child application interface other than the common resource. Finally, the terminal generates and displays the first child application interface according to the common interface container.
