Provided are a steel material and a method for producing the same. The steel material exhibits excellent hydrogen embrittlement resistance in a high-pressure hydrogen gas environment and is, therefore, suitable for use in hydrogen storage tanks, hydrogen line pipes, and the like. A steel material for a high-pressure hydrogen gas environment has a predetermined chemical composition. The steel material has a tensile strength of 560 MPa or higher, and a fracture toughness value KIH exhibited by the steel material in a high-pressure hydrogen gas atmosphere is 40 MPa ·m1 / 2 or higher.

The application discloses a kind of distributed edge collaborative video analysis methods based on multi-agent reinforcement learning, through mutual cooperation of edge nodes, jointly learn the optimal strategy of video frame pre-processing, model selection and request scheduling, to minimize the overall cost of system.The application models each edge node as an agent, which is an autonomous entity and makes distributed control decisions by observing its local state.The application uses an attention mechanism to distinguish the importance of information collected from different edge nodes, and its performance is verified by deploying a video analysis test platform with multiple edge nodes, and extensive experiments are conducted using real-world datasets and experimental settings.The experimental results show that compared with existing baseline methods, the application can significantly improve the overall reward by 33.6%-86.4%.

This invention discloses a closed-loop soil improvement method for vineyards using organic fertilizer synergy, comprising the following steps: seasonal directional grass cultivation, preparation of Bacillus subtilis agent, preparation and application of self-made organic fertilizer in the early stage of vineyard establishment, and closed-loop synergistic improvement method; the closed-loop synergistic improvement method is divided into early stage improvement and late stage improvement, relying on grass return to the field and Bacillus subtilis to maintain soil fertility and nutrient cycle.
