【摘要】 采用１％ＮａＨＣＯ＿３水溶液对兴安落叶松（Ｌａｒｉｘｇｍｅｌｉｎｉ）木材进行了处理，并用红外光谱、扫描电子显微镜和化学分析等方法对处理前后木材的尺寸稳定性、吸湿性、官能团和超微构造的变化进行了比较和分析。从而确定影响兴安落叶松木材尺寸稳定性的主要因素。本究研为兴安落叶松木材的改性和利用提供了理论依据。更多还原

【Abstract】 The samples of larch（Larix gmelini） were treated with 1%:solu-tion of NaHCO₃. The dimensional stability,moisture absorption,functionalgroups and ultrastructure changes of the samples before and after the treat-ments were analyzed and compared using IR,SEM and chemical analysis.Themain factors which influence the dimensional stability are found. The researchresults laid a foundation of modification and utilization of larch wood.更多还原
