This invention belongs to the field of heavy metal pollution remediation technology, and relates to the preparation and application of a cadmium passivating agent for weakly alkaline soil. The weakly alkaline soil cadmium passivating agent mainly comprises the following components by weight: 30-50 parts of a mineral complex, 40-60 parts of a bioactive component, and 5-15 parts of an auxiliary stabilizer. The mineral complex includes natural sepiolite, calcium-based bentonite, and a polyether-polyester diblock copolymer; the bioactive component includes microbial agents, phosphorus-modified biochar, lecithin, and phosphatidylserine; and the auxiliary stabilizer includes nano-hydroxyapatite and a chitosan-grafted polyaspartic acid complex. This weakly alkaline soil cadmium passivating agent exhibits excellent remediation effects on cadmium in contaminated soil, effectively preventing or reducing the entry of cadmium and other heavy metals into the food chain, and has significant market potential.

This invention discloses a path planning method based on the soft fusion of virtual chemical fields and reinforcement learning, belonging to the field of robot navigation and artificial intelligence technology. The method includes the following steps: constructing a confined space containing obstacles, setting the initial and target positions of the moving subject; constructing a virtual chemical field that attracts the target and repels the obstacle, calculating the field strength characteristics and evolution trend, and scheduling forward movement, fine-tuning, and large-scale turning to generate guiding actions; constructing a reinforcement learning policy model to generate policy actions; introducing an exponential decay soft fusion mechanism to select either a guiding action or a policy action as the final action with decreasing probability; driving the subject to move to a new position, obtaining a reward according to a reward function, and storing the interaction samples in an experience pool; updating the policy model after the samples reach a threshold, repeating until convergence; and generating a collision-free path from the initial position to the target when obstacles change. This invention achieves efficient adaptive collision-free path planning through the soft fusion of biomimetic guidance and reinforcement learning.

This application relates to the field of battery technology, and more particularly to a battery pack. The battery pack includes a housing, a cover, a heat spreader, a cooling component, and multiple battery cells. The housing has mounting slots; the cover is located at the opening of the mounting slot; each battery cell is spaced apart in the mounting slot, and each cell has a shoulder at the end furthest from the bottom of the slot; the heat spreader connects to each shoulder; the cooling component is located on the side of the heat spreader facing away from the shoulder, and a cooling channel is formed inside the cooling component, through which a cooling medium flows to achieve heat exchange with the heat spreader. This battery pack, by incorporating a combined heat dissipation structure of a heat spreader and a cooling component at the shoulder, firstly achieves targeted heat dissipation in this core heat-generating area, reducing heat accumulation at the shoulder from the source, avoiding the generation of thermal island effects, effectively improving the overall thermal management performance of the battery pack, slowing down cell aging, and extending the battery pack's service life.
