Operation · Maintenance · Spare parts — a paper-machine O&M knowledge system organized by paper grade. All 17 lectures cover the common foundation, utility systems, grade-specific volumes, and management loop: first build the methodology, then cross the cross-grade systems, then land by grade, and finally close with shutdown maintenance and the knowledge map. Parameters carry units and formulas carry annotations — bilingual (ZH/EN).
