Urban rail transit systems require reliable decision-support methods to assist operators in handling complex fault events. Although large language models provide strong reasoning and knowledge integration capabilities, their open-ended generation may produce responses that are difficult to align with operational proced...

Spinal cord injury (SCI) is a devastating condition of the central nervous system characterized by complex pathophysiological processes, including primary mechanical damage and secondary injury cascades, ultimately leading to permanent neurological deficits. Current standard treatments—including surgical decompression...
Results indicate that the proposed multi-stage post-training framework effectively improves LLM performance on real-world text-based fault diagnosis, and provides a practical and extensible solution for intelligent maintenance decision support in complex electromechanical systems.
