摘要：

Collapse-type shrinkage is one of highly refractory drying defects in low-medium density plantation-grown eucalypt wood used as solid wood products. Basic density (BD), microfibril angle (MFA), double fibre cell wall thickness (DWT), proportion of ray parenchyma (RP), unit cell wall shrinkage, total shrinkage and residual collapse, which are associated with collapse-type shrinkage characteristics, were investigated by using simple regression method for three species of collapse-susceptible Eucalyptus urophyll,, E. grandis and E. urophylla×E.gr...

摘要(中文)：

皱缩型收缩是低中等密度桉树人工林木材被用于实木产品加工时最难以克服的缺陷之一。为此,本研究对种植在广西国营东门林场的3 种易皱缩桉树（尾叶桉,巨桉,尾巨桉）木材的基本密度,微纤丝角（MFA）,纤维双倍壁厚（DWT）, 射线薄壁组织率（RP）, 单位胞壁收缩率,总收缩率和残余皱缩几个与皱缩相关的材性指标进行了研究。结果表明:1)单位胞壁收缩率与基本密度具有极强的线性正相关性,与纤维双倍壁厚表现出中等至强的线性正相关性,而与射线薄壁组织率和微纤丝角呈现弱至中等的线性负相关性。基本密度能作为单独因子很好的预测单位胞壁收缩率（R2≥0.9412）; 2)总收缩率与基本密度、纤维双倍壁厚、射...
