This invention discloses a multi-source electromagnetic noise suppression method based on noise classification and deep learning, belonging to the field of geophysical electromagnetic exploration technology. The method includes: segmenting and preprocessing the original electromagnetic observation sequence; using an improved U-Net network with an encoder embedded in a Mamba time-series modeling module for low-frequency noise suppression; identifying strong noise types in the data segments using a ROCKET classifier; based on the classification results, calling a second improved U-Net network trained for the corresponding noise type for class-based targeted denoising; and finally, splicing the data segments to obtain complete, high-quality data. This invention, through a phased processing framework of "low-frequency pre-suppression—noise classification—class-based denoising," combined with the strong time-series modeling capabilities of the Mamba module and the efficient classification performance of ROCKET, significantly improves the suppression accuracy and signal fidelity for complex, multi-source electromagnetic noise, and is particularly suitable for processing ground and airborne electromagnetic exploration data.

The utility model relates to the technical field of spiral spray guns, and particularly discloses a hot melt adhesive spiral spray gun which comprises a gun body, an air flow heating cavity, an air inlet, an air guide hole, a cavity sealing piece and an electrical bar are arranged at the bottom of the gun body, the electrical bar is used for heating air flow entering the air flow heating cavity, and the air flow heating cavity is composed of a plurality of bent channels; the glue spraying valve is connected and mounted on the gun body through a screw, a through hole is formed in the center of the glue spraying valve, and a coaxial two-stage threaded seat, a nozzle, a biconical valve core and a gas guide sleeve are sequentially arranged at the bottom of the glue spraying valve; by means of the conical matching structure of the air guide sleeve and the nozzle and the design of the air guide groove, a stable spiral airflow field is formed, spiral rubber threads with the width as low as 3 mm can be sprayed in combination with control over flowing of rubber liquid through the double-conical valve element, the rubber threads are evenly and continuously distributed, and the spraying effect is good. And the narrow bonding requirements of paper bag sealing, bonding of a wet locking cover and a packaging box and the like are met.
