The application discloses a deep-sea rare biological target detection method based on a stable diffusion model and belongs to the technical field of deep-sea biological target detection. Rare biological categories are determined from a deep-sea benthic biological real scene data set, and a foreground region image is extracted to construct a real target data set, a foreground image generation model is trained, and diversified synthetic foreground images are generated. A conditional control network is used to generate an external drawing of the foreground image according to a layout mask, the synthetic foreground image is fused with a deep-sea background, and a target position label is automatically generated according to the layout mask to obtain a synthetic scene image. After the synthetic quality is screened and the label frame is refined, the synthetic scene image is combined with the real scene data set to construct an enhanced training data set, and a target detection model is trained. The application solves the problem that the target detection performance is limited due to the long-tail distribution effect of the deep-sea exploration data set, and improves the detection capability of the target detection model for the rare biological categories.

This invention discloses a method and system for multi-stage processing and reverse transcription stabilization of deep-sea in-situ metatranscriptomic RNA, relating to the fields of deep-sea biotechnology and marine instrumentation. Within a continuous, sealed fluid channel, the following components are connected in series: a filtration and enrichment chamber, a controlled decompression unit, a programmable control unit, and at least one multifunctional reaction chamber. The multifunctional reaction chamber integrates a temperature control system. At least one set of bidirectional opposing electromagnets is disposed on the outer wall of the multifunctional reaction chamber. The programmable control unit controls the on / off state and current of the bidirectional opposing electromagnets, generating a dynamically switchable spatial magnetic field gradient within the multifunctional reaction chamber. This drives magnetic microspheres within the chamber to perform at least one of the following operations without centrifugation: adsorption and aggregation, suspension and mixing, in-situ washing, inter-chamber transfer, and elution / desorption. All biochemical operations are completed within a continuous, sealed fluid channel, eliminating cross-contamination between the sample and the external environment and achieving fully automated sample processing in deep-sea environments.
