A method for simulating a magnetic Barkhausen noise signal in a stress-containing dual-phase ferromagnetic material. A spin plane in an Ising model is subjected to mesh partitioning, and different model parameters are assigned to meshes of sub-spin planes obtained by partitioning to simulate different magnetic characteristics of two components. The proportion of the number of meshes respectively occupied by the two components can be adjusted to simulate a change in the component proportion. The Ising model is solved by using a Monte Carlo algorithm to obtain the magnetic Barkhausen noise signal of the dual-phase material having different component proportions. The relationship between a spin interaction coefficient and the stress in the Ising model is described by using a quartic polynomial, the relationship is substituted into a dual-phase material magnetic Barkhausen noise signal simulation model, and the change rule of magnetic Barkhausen noise signal characteristics under the combined action of the component proportion and the stress is analyzed. By means of the method, it is predicted that the influence rule of the component proportion and the stress change on magnetic Barkhausen noise is consistent with an experimental result.

ALL-COMPONENT RAPID MICROWAVE DIGESTION AND NOBLE METAL ION LIQUID EXTRACTION METHOD FOR WASTE CIRCUIT BOARD
An all-component rapid microwave digestion and noble metal ion liquid extraction method for a waste circuit board, belonging to the field of hydrometallurgy. As microwave can penetrate a leaching medium and directly heat a circuit board, microwave-assisted leaching can enhance mass transfer and heat transfer in a traditional leaching process, greatly reduce leaching time, and increase leaching efficiency.
