Abstract: This application provides a screen casting method, a device, and a storage medium. In a screen casting process, when a sound output device is switched to the screen casting transmit end, whether the screen casting transmit end outputs a sound depends on a current status of an audio status switching control, thereby ensuring that whether the screen casting transmit end outputs a sound can be consistent with an expectation of a user in a screen casting scenario. In addition, in the screen casting method provided in this application, when whether the screen casting transmit end outputs a sound is set based on a click operation performed by the user on the audio status switching control, an icon corresponding to the audio status switching control is dynamically modified based on an audio status (mute or non-mute) corresponding to the audio status switching control.

Abstract: The present disclosure discloses an oil shale semicoke adsorption inhibitor and use thereof in concrete preparation. The adsorption inhibitor is prepared by the following steps: sequentially adding 50-52.5 weight parts of an anti-corrosion rheological agent, 5-20 weight parts of methanol, 0.5-2 weight parts of sulfonated melamine, 2-5 weight parts of EDTA, 20-30 weight parts of an organosilicon compound, and 5-10 weight parts of stearate into a mixing container, and performing stirring well. The anti-corrosion rheological agent is a microbead. The adsorption inhibitor solves problems of strong water absorption, high adsorption of a water reducing agent, etc. of oil shale semicoke, reduces the use amount of the water reducing agent in concrete production, and can also reduce power consumption during grinding, thereby realizing high-value resource utilization of the oil shale semicoke.
