| 摘 要： | 论述了人工林落叶松木材经醇溶性低分子量酚醛树脂注入处理，改善其尺寸稳定性，即通过各种不同质量分数的PF树脂处理对比试验后，PF树脂质量分数在20％～30％时，木材的抗胀(缩)率达到60％以上，并且随着树脂质量分数的增加，木材的开裂减少。

| Abstract: | The properties of surface layers for artificial larch were analyzed by treating with a low molecular weight phenol-formaldehyde resin (PF) in order to improve i ts dimensional stability. Contrasting test showed that wood specimens treated wi th the PF resin had an 60%~70% of anti-swelling efficiency when the concentratio ns of PF resin was within 20%~30%, and the cracks of larch wood decreased with P f concentration increasing. |
