Abstract: A method for capturing carbon dioxide includes: spraying an alkaline solution through a first spray structure; temporarily storing a solution, in a first temporary storage structure, and making the solution flow out through the first spray structure; detecting a concentration of hydroxide and/or a concentration of carbonate of the solution, and supplementing one of an alkaline solution and water into the first temporary storage structure according to the concentration of the hydroxide and/or the concentration of the carbonate; and in a case that the concentration of the hydroxide is less than or equal to m and the concentration of the carbonate is n, controlling a first pump body or a third pump body to stop running, so that the solution enters an electrolysis device for an electrolysis. Adopting the present disclosure solves problems in that capture efficiency of carbon dioxide gas and overall energy consumption are relatively difficult to control.

Abstract: Embodiments of the present disclosure provide a connection processing method and apparatus, an electronic device, and a computer-readable storage medium. The connection processing method includes: initializing, in response to receiving a first connection request from a source device, an abnormality processing policy; transmitting first connection information to a target device of the first connection request; transmitting, in response to receiving a first connection information confirmation message transmitted by the target device, a first connection confirmation message to the source device; generating the abnormality processing policy; transmitting a first notification to the target device, the first notification including the abnormality processing policy; and transmitting a second notification to the source device, the second notification including the abnormality processing policy.

Abstract: A method for identifying a dry salt flat based on the sentinel-1 data is provided. The method includes: carrying out field survey and acquiring data; processing sentinel-1 data; determining backscattering values, spectrum characteristics and colors of different polarization; and determining a classification criterion and carrying out threshold classification.

Abstract: A co-hosting system, method, apparatus and device, and a storage medium are provided. The co-hosting method includes: replying, by a co-hosting service server side, to a co-hosting inviter side with a response message carrying a virtual room identifier, in response to a co-hosting request received from the co-hosting inviter side, where the response message indicates a successful reception of the co-hosting request, and the virtual room identifier is used to enable the co-hosting inviter side to enter a virtual room; and forwarding, by the co-hosting service server side, a co-hosting acceptance message to the co-hosting inviter side, in response to the co-hosting acceptance message for the co-hosting request received from a co-hosting invitee side.
