The invention discloses a ship detection method suitable for offshore extreme rain and snow weather, electronic equipment and a computer storage medium, and belongs to the field of offshore ship detection. Comprising the following steps: processing a ship image data set through a dark channel prior defogging algorithm, ensuring equalization of various ship samples through data diffusion, extracting ship features, performing effective information fusion among features of different scales by a feature fusion network, classifying and positioning deep and shallow features fused with different levels, and obtaining a ship image data set; therefore, the classification and the position of the target ship are obtained, the detection frames which are low in confidence coefficient and are excessively overlapped and the position and category information of the ship in each frame are screened out through a maximum suppression algorithm, and the real-time detection of the marine ship video stream is completed.

The application discloses a Tibetan prosody structure prediction method based on syntax information, relates to the technical field of speech synthesis, and is applied to the prosody structure prediction field in Tibetan speech synthesis. The Tibetan prosody structure prediction method based on syntax information comprises the following steps: S1, Tibetan text analysis and virtual word connection quantization are completed, syntax probability, hierarchical focus and pause difference are extracted, and a Tibetan prosody prediction database is stored and constructed after preprocessing; S2, boundary discrimination is performed based on virtual word connection relationship strength, influence range hit marking and word sequence distance; S3, entropy feature analysis is performed through syntax role probability data and boundary determination data; S4, three-layer prosody boundary type sequences are generated according to boundary assignment, and over-dense pauses are inhibited; and S5, rhythm intensity evaluation is performed through pause duration difference and syntax information entropy data. The problems of pause confusion and increased understanding burden caused by the misplacement of prosody and semantic hierarchy in Tibetan long speech synthesis are solved.

The invention relates to the field of meteorological prediction, and provides a multi-mode north pole climate change prediction and regulation and control mechanism analysis method. The purpose of the invention is to predict the climate change of the arctic region through the relationship among NPO, AMOC and arctic near-surface air temperature. According to the method, by constructing and verifying a large sample data set containing AMOC substitute data and north pole SAT historical observation data, the performance and deviation of the CMIP6 mode in simulation of AMOC and north pole SAT changes are evaluated. Then, a physical mechanism of the influence of the AMOC on the north pole SAT is disclosed, and the regulation and control effect of the NPO internal change rate on the relationship between the AMOC and the north pole SAT is explored; based on this, the future climate change scene is simulated, the mode parameters are adjusted to accurately reflect the influence of AMOC and NPO on the north pole SAT, and the change trend of the future north pole SAT and AMOC is predicted to evaluate the reliability of mode prediction. The method is used for predicting the climate change of the arctic region, and the prediction accuracy of the future change of the arctic climate is improved by deeply understanding the interaction between different climate modes.

And meanwhile, the service life of the printer is prolonged.

This invention discloses a storage box comprising a box body for installation within a map pocket in a car door panel and rotatable relative to the door panel, allowing the box body to switch between a first position and a second position. In the first position, the box body rotates into the map pocket; in the second position, it rotates out of the map pocket. The box body includes an inner shell and a cover plate. The inner shell is disposed within the map pocket and rotatable relative to it, while the cover plate is disposed within the inner shell and rotatable relative to it, allowing the cover plate to switch between a first position and a second position. In the first position, the cover plate closes the inner shell; in the second position, it opens the inner shell. This storage box solves the problem of traditional map pockets having limited functionality and unclear partitioning by improving the neatness and aesthetics of the vehicle interior space through its concealed design.
