The application discloses a preparation method of a high-entropy brazing filler metal for ceramic composite brazing, and comprises the following steps: (1) selecting elements, selecting high-purity materials, mixing and smelting; (2) performing metallographic test analysis, observing the structure and morphology, selecting a maximum single-phase region, and determining the elements in the region and the corresponding atomic percentage; (3) selecting high-purity materials, mixing and smelting; (4) performing metallographic test analysis, observing the structure; if the structure and component distribution are uniform, the preparation is completed; if the structure and component distribution are not uniform, the element composition of the maximum single-phase region is screened out, the elements in the region and the corresponding atomic percentage are determined, steps (2) and (3) are repeated until the structure and component distribution are uniform, and the preparation is completed. The high-entropy brazing filler metal obtained through the method is more suitable for homogenous or heterogeneous brazing of light-weight high-temperature-resistant ceramic matrix composites.

This invention relates to the field of underwater acoustic communication technology, specifically a joint multi-branch equalization and polar code decoding method for underwater acoustic communication. Compared with existing technologies, the multi-branch equalization and polar code decoding are not independent of each other, but form a loop between the two modules. By exchanging soft information between the two modules, the joint performance can be further improved. Simulation results verify the effectiveness of the loop iteration of this invention. The performance comparison with existing algorithms also illustrates the advantages of the proposed invention.
