The application discloses a conjugated polymer of chlorobenzene, o-dichlorobenzene or m-dichlorobenzene and EDOT as well as a preparation method and application thereof, and belongs to the field of polymer electrochromic materials. By introducing chlorine atoms as intermediates in different active sites of benzene and EDOT as a strong electron-donating group, the obtained conjugated polymer has the characteristics of a wider redox peak, good optical contrast, fast response time, high coloring efficiency, good stability and the like.

This invention discloses a tunable nanoantenna and its fabrication method, belonging to the field of nanoantenna technology. The tunable nanoantenna comprises, from top to bottom: an ordered metal mesh nanoelectrode layer, Fe... 3 O 4 The invention comprises a magnetic nanosphere layer, a silicon nanopillar micro / nanostructure layer, a substrate layer, and a lower electrode layer. This invention proposes a tunable nanoantenna and its fabrication method. Specifically, this invention combines silicon nanopillars with Fe... 3 O 4 By combining magnetic nanospheres and utilizing their synergistic effect, a composite nanoantenna with magnetic response and optical resonance characteristics can be constructed. This not only breaks through the limitations of single-material control, but also enables more flexible performance control through the dual effects of magnetic and optical fields.

The present application relates to a biomedical image copy detection method, belonging to the technical field of digital information security, which can solve the problem of low accuracy, great detection difficulty and low efficiency of the image copy detection method in the prior art when used for biomedical image copy detection. The method steps of the present application are: S1, input the path of the query image set and the path of the reference image set; S2, input the query image set and the reference image set into the self-supervised image copy detection model to generate image feature vectors; S3, use the faiss library to construct the index of the image feature vectors in the reference image set; S4, traverse and calculate the minimum Euclidean distance between the image feature vectors of the query image set and the image feature vectors in the reference image set according to the index of S3; S5, obtain the suspected copy image pair based on the minimum Euclidean distance obtained in step S4; S6, judge whether the biomedical image is a copy image according to each suspected copy image pair.

This invention relates to a conveying device for conveying a motor vehicle body (2) along a conveying path (4) during painting in motor vehicle manufacturing. The conveying device includes a chain conveyor (5) having chain strands (6) circulating along the conveying path. Fixed receiving elements (7) and loose receiving elements (8) are arranged at predetermined distances from each other along the entire length of the chain strand and are movable along the conveying path by means of the chain strands. The fixed receiving elements constitute crossbeams detachably connected to the motor vehicle body, and the loose receiving elements have resting areas (12) on which another crossbeam (13) detachably connected to the motor vehicle body can be supported. The crossbeams maintain the same crossbeam distance across the vehicle model, corresponding to the distance between the fixed receiving element and the following loose receiving element. The invention also relates to a method and painting apparatus for painting a motor vehicle body.
