The invention discloses a stainless steel weld defect efficient detection method based on multi-domain expression data enhancement and model self-optimization. The method comprises the following steps: deriving a one-dimensional echo time domain signal to spatial domains such as a time-frequency domain, a Gramb angle field domain and a Markov transfer field domain; sequentially inputting the data set constructed by each spatial domain into the MobileNetV3 neural network, and selecting the spatial domain with the most abundant feature expression as a final training data set; constructing a multi-scale depth separable convolution to improve the MobileNetV3 so as to enhance the recognition performance of the network; providing a particle swarm-chaos sparrow search algorithm for automatic optimization of a network structure and parameters; and adopting the CPU + FPGA heterogeneous cooperative calculation to accelerate the reasoning and recognition application speed of the defects. Five types of weld defects such as incomplete fusion, air holes, slag inclusion, incomplete penetration and cracks are taken as objects, the recognition accuracy of the five types of weld defects can reach 98.75%, and the method has practical engineering application value.

The invention relates to a screening method of silkworm hemocyte specific expressed genes and a method for analyzing and finding a hemocyte specific expression regulation element through cloning of a protease O gene promoter. The hemocyte specific expression regulation element is manufactured through the following steps that 1, a hemocyte specific expression candidate gene protease O gene is screened out through silkworm tissue chip expression data, transcriptome data, a quantitive RT-PCR and other methods, and the silkworm hemocyte specific expression of the gene is verified successfully; 2, a related gene promoter is successfully cloned, and functional analysis is carried out; 3, a Bac-to-Bac rhabdovirus expression system is successfully improved, an effective hemocyte promoter detection system is built, the activity of the candidate gene promoter is detected at the cell and the individual level, and tissue specificity of the promoter is verified; 4, the silkworm hemocyte specific gene protease O gene promoter is obtained through the study, and it is analyzed and found that the promoter is provided with the tissue specificity regulation element in the section between the upstream -333 and -80 of a transcriptional start site. The specificity expression of the gene on hemocyte is controlled.
