木材皱缩的研究现状及发展趋势

通过总结和分析国内外关于木材皱缩的研究现状，指出皱缩深度、皱缩因子、体积收缩率、干缩率等4项指标能够合理地评价木材皱缩的程度；采用预冻处理、热处理、加压或拉伸处理以及后期调湿处理能够在一定程度上减少皱缩的产生；并讨论了木材皱缩研究的发展趋势。

The Present Condition and Development Tendency of the Research on Wood Collapse

This paper summed up and analyzed the present study on collapse property of wood at home and abroad. It showed that the index of collapse depth, collapse factors, volumetric shrinkage rate, and drying shrinkage rate could criticized the extent of collapse of wood reasonably. After the treatment, such as pre freezing, heating, compressing or tensiling, later conditioning,the collapse could be diminished.The development tendency about wood collapse was discussed.
