Abstract: Embodiments of the disclosure provide a method, apparatus, device, and storage medium for content capturing. The method includes, presenting a first capturing page corresponding to a single-segment capturing mode to capture a first video segment; in response to an indication of capturing completion being detected while the first capturing page is being presented, presenting a first editing page for editing at least the first captured video segment; and presenting a second capturing page to capture a second video segment based on an indication of new capturing being detected while the first editing page is being presented. In this way, it is possible for users to conduct content creating more easily and quickly, and different capturing requirements can further be met.

Abstract: Embodiments of the disclosure provide a method, apparatus, device, and storage medium for content capturing. The method includes, in response to a capturing start instruction, presenting a capturing start page which including at least a capturing control; in response to detecting a trigger instruction for the capturing control, switching from the capturing start page to a capturing page for video capturing, the capturing page including at least a stop control and a pause control, and the stop control being presented in a more prominent way than the pause control; and in response to detecting a trigger instruction for the stop control, switching from the capturing page to a video editing page, the video editing page being used to edit a captured video. In this way, it is possible for users to quickly perform video capturing and directly enter the editing page to complete editing of a work.

Abstract: The present disclosure provides a video processing method and apparatus, a device, and a storage medium. The method comprises: when a target video is being played back, displaying a playback progress bar in a preset countdown mode, wherein the playback progress bar does not support adjustment of a playback progress function; and if detected that playback of a last frame of the target video has ended, then stopping the playback of the target video, displaying a mask layer on a video picture of the last frame of the target video, and displaying preset prompt information on the mask layer, wherein the preset prompt information is used for prompting that the target video only supports playback once.

Abstract: A curing agent for disposal of municipal solid waste incineration (MSWI) fly ash and a preparation method and use method thereof are provided. In the present disclosure, a loofah nanofiber crystal, a rice husk ash (RHA), sodium hydroxide, and water are adopted as raw materials to prepare the curing agent, and the curing agent can effectively realize the safe disposal and curing of heavy metals in an MSWI fly ash. The highest curing rates of the curing agent for heavy metals Pb2+, Zn2+, Cd2+, Cr3+, and Cu2+ can reach 99.7%, 99.4%, 99.5%, 98.7%, and 99.5%, respectively. The special three-dimensional (3D) cross-linked network structure of the loofah nanofiber crystal and the excellent physical and chemical adsorption properties and ion exchange capacity of the RHA are fully used in the curing agent of the present disclosure.

Abstract: A method for synthesizing a copper-silver alloy includes an ink preparation step, a coating step, a crystal nucleus formation step and a crystal nucleus synthesis step. In the ink preparation step, a copper salt particle, an amine-based solvent, and a silver salt particle are mixed, thereby preparing a copper-silver ink. In the coating step, a member to be coated is coated with the copper-silver ink. In the crystal nucleus formation step, at least one of a crystal nucleus of copper having a crystal grain diameter of 0.2 ?m or less and a crystal nucleus of silver having a crystal grain diameter of 0.2 ?m or less is formed from the copper-silver ink. In the crystal nucleus synthesis step, the crystal nucleus of copper and the crystal nucleus of silver are synthesized.

Abstract: A system for pest control in a confined space using flue gas from a biomass power plant is disclosed. The system contains a flue gas treatment device including a discharge pipe; a storage tank of treated flue gas; a control unit; a first regulating valve; a first pressure monitoring sensor; a carbon dioxide concentration monitoring sensor; and a first atmospheric valve.

Abstract: A method for pest control in a confined space using flue gas from a biomass power plant. The method includes: treating flue gas from a biomass power plant to yield treated flue gas having a volume concentration of carbon dioxide exceeding 85 volume %, and conducting pest control in a confined space according to the following steps: continuously aerating the confined space with the treated flue gas during a fallow period to allow a gas pressure in the confined space to reach between 0.110 and 0.140 megapascal of absolute pressure and the volume concentration of carbon dioxide in the confined space to reach between 50 and 90 volume %.
