Abstract: The present disclosure provides a method and system for mining rare earth ore using a direct current. The system includes: liquid injection holes arranged in a mining area; electrodes arranged in the liquid injection holes; a leaching agent added into the liquid injection holes; and an electrification control system dividing the mining area into M equal parts and electrifying the electrodes using a cyclical alternate electrification method from 1 to M. In an Nu electrification cycle, all electrodes of an (M×n+N)th row are connected to a positive electrode of a power supply, and all electrodes of an (M×n+N+1)th row are connected to a negative electrode of the power supply. The cyclical alternate electrification method reduces at least (M?1)/M of power consumption, and the rare earth mining efficiency is improved.

Abstract: The present disclosure provides a method for optimizing parameters of a ladder-type carbon trading mechanism based on an improved particle swarm optimization (IPSO) algorithm. The method first obtains information and operating data of a park-level integrated energy system, establishes equipment models and constraints of the park-level integrated energy system, and establishes a ladder-type carbon trading model; then encapsulates a process of optimized low-carbon dispatching of the park-level integrated energy system as a fitness function whose input is parameters of a carbon trading mechanism and output is a carbon emission of the system; and finally, introduces an IPSO algorithm to optimize the fitness function, and outputs optimization result information of the algorithm. The present disclosure verifies effectiveness and rationality of the model and the method that give full play to a role of the ladder-type carbon trading mechanism in the park-level integrated energy system through example analysis.

Abstract: A method for acquiring a virtual frame number and a virtual slot number at a virtualization platform is provided. The virtualization operating system receives a command for creating a virtual server sent from a virtualization management platform. In response to the command for creating a virtual server, the virtualization operating system creates a virtual server on a board. After creating the virtual server, the virtualization operating system sends a frame number request message carrying an identifier of the virtual server to the virtualization management platform. The virtualization operating system receives a virtual frame number corresponding to the identifier of the virtual server sent from the virtualization management platform. The virtualization operating system obtains a virtual slot number corresponding to the identifier of the virtual server according to the virtual frame number.
