Abstract: A deep-sea sound source localization method, a computer device and a storage medium. The method includes: deploying at least two underwater gliders in a designated sea area, so as to respectively record a broadband signal which is emitted by a broadband sound source (1); obtaining a waveform envelope of the signal, and then calculating a waveform envelope of a simulated signal (2); performing cross-correlation analysis on the two waveform envelopes (3); and determining an estimated value of a distance from the sound source, and finally obtaining an estimated position of the sound source by means of a geometrical relationship (3). By means of the method, deployment of a large-depth vertical receiving array is not required. The system has low complexity, and is easy to deploy and operate, which can be applied to a relatively large area.

Abstract: The present disclosure relates to a solar cell, a preparation method thereof, and a photovoltaic module. The solar cell includes a semiconductor substrate, passivating contact structures, a dielectric layer, and first electrodes. The semiconductor substrate includes a first surface and a second surface opposite to each other. The semiconductor substrate includes passivation regions and passivated contact regions, which are alternately arranged along a first direction. The first direction is perpendicular to a thickness direction of the semiconductor substrate. The passivating contact structures are disposed on the second surface and correspondingly disposed on the passivated contact regions. Each passivating contact structure includes an electrically conductive passivation layer. The dielectric layer at least covers the second surface in the passivation regions. The first electrodes are disposed on the passivating contact structures at a side away from the semiconductor substrate.

Abstract: A coating slurry with high adhesion and high ionic conductivity, a preparation method thereof, and a lithium battery separator are provided. The coating slurry with the high adhesion and the high ionic conductivity includes: PEAE: 1 to 60 parts; a dispersing agent: 0.01 to 10 parts; a wetting agent: 0.01 to 15 parts; and a solvent: 100 parts. The PEAE can be evenly coated on a basal membrane to form a lithium battery separator, which solves the problem that pure PEAE cannot be directly and evenly coated on a separator. The PEAE is coated on the basal membrane for the first time to prepare the lithium battery separator, which ensures that the lithium battery separator has characteristics of the high adhesion and the high ionic conductivity.
