The invention relates to the technical field of ocean platform pipeline design, in particular to an ocean platform pipeline laying method based on reinforcement learning, and the method comprises the following steps: S1, dispersing a pipeline laying region into a three-dimensional grid matrix according to the physical size of an actual cabin of an ocean platform, and marking a pipeline starting point, a pipeline ending point and an impassable region; s2, performing Q-Learning algorithm parameter initialization configuration, defining an action space adaptive to the linear movement characteristics of the ocean platform pipeline, constructing a Q value matrix adaptive to three-dimensional space coordinates and actions, and performing initialization; s3, entering a training round, and continuously updating the value evaluation matrix by dynamically adjusting a greedy criterion, a multi-dimensional reward mechanism and a time sequence difference learning rule; and S4, after the training is completed, starting from the starting point based on the converged Q value matrix, selecting an optimal action through a greedy to generate a final pipeline path, and improving the quality and search efficiency of pipeline laying on the ocean platform.

The utility model discloses a sample plate piece cart, which relates to the technical field of carts, and comprises a frame, a support assembly and a roller assembly, the support assembly comprises a plurality of first support rods, a plurality of second support rods and two adjusting rods arranged on the frame at intervals along the length direction of the frame, the number of the first support rods is more than one, and the number of the second support rods is more than one. The number of the first supporting rods is equal to that of the second supporting rods, the first supporting rods are arranged on one adjusting rod at intervals in the height direction of the frame, and the second supporting rods are arranged on the other adjusting rod at intervals in the height direction of the frame. The first supporting rod and the second supporting rod located at the same height are used for supporting the two ends of the sample plate piece correspondingly. The roller assembly is arranged at the bottom of the frame. By arranging the first supporting rods and the second supporting rods which are arranged in the vertical direction, the sample plate pieces can be stacked in a layered mode, contact between the sample plate pieces is eliminated, and therefore the situation that the sample plate pieces deform due to gravity extrusion is eliminated.

A battery cell according to an embodiment of the present application includes an electrode assembly, a can accommodating the electrode assembly, and a first electrode terminal electrically connected to the electrode assembly. The first electrode terminal includes a current collector surface positioned at an inner side of the can, a post portion extending from the current collector surface and penetrating the can, and a terminal face extending from the post portion and positioned at an outer side of the can, wherein, in the post portion, a first hole is formed through the current collector surface, and in the terminal face, a second hole is formed that communicates with the first hole and is smaller than the first hole, the second hole being sealed at a surface of the terminal face.
