“木材多尺度结构的干缩湿胀研究进展”综述文献

综述木材宏观尺度（无疵试样）、介观尺度（生长轮）和微观尺度（木材细胞）3 种层级单元的干缩湿胀行为及其滞后现象，分析木材不同尺度结构的干缩湿胀行为发生和演变规律，介绍基于多尺度结构的木材干缩湿胀测试方法和技术手段。同时，对今后开展木材多尺度结构干缩湿胀行为研究提出建议。

This review summarizes the shrinkage-swelling behavior and its associated hysteresis phenomenon of three hierarchical units of wood: macroscale (defect-free specimens), mesoscale (growth rings), and microscale (wood cells). It further analyzes the occurrence and evolutionary patterns of shrinkage-swelling behavior in wood structures across different scales, and introduces the test methods and technical approaches for characterizing wood shrinkage and swelling based on multi-scale wood structures. Finally, it puts forward targeted suggestions for future research on the shrinkage-swelling behavior of wood at multi-scale structures.
