Abstract: The partition monitoring method for concrete dam operation key parts provided by the disclosure firstly utilizes the extracted monitoring data time-frequency vector to partition the concrete dam key parts, and on this basis, obtains time series measurement data of different types of monitoring instruments with high temporal and spatial correlation, so as to establish a graph structure. Then, the dependence of time dimension and variable dimension of multivariate time series data is captured, and the relationship between further learning and representation of graph attention network is provided. Furthermore, the final feature representation of time series measured data is obtained, and finally the anomaly score is calculated through the final feature representation to detect anomalies. The complementary mutual verification of multiple measuring points of monitoring instruments with various types is realized. The structural integrity and spatial distribution law of concrete dams are fully embodied.

Abstract: A method for preparing a sodium super ionic conductor solid electrolyte by low-dimensional crystallization belongs to a field of energy materials. The method is based on the theory of negative ion coordination polyhedron growth unit, and uses low-temperature plasma as a protective gas of a spray drying equipment. While evaporating the solvent in a sodium super ionic conductor solid electrolyte precursor slurry, plasma active groups modify the particle surface of the sodium super ionic conductor solid electrolyte precursor particles in-situ. A free space dimension of crystal growth in the crystallization process is reduced, and directional growth of crystals in the solid phase sintering process is induced. Secondly, the dispersion stability of the sodium super ionic conductor solid electrolyte precursor particles is improved. Compared with the traditional high-temperature solid-state sintering process, the method has the advantages of fast crystallization speed, high crystal purity and integrity, good compactness, and uniform particles.
