  1. 用X射线扫描密度计测量气干材含水率及其每一年轮的水分分布。

    In this paper , the moisture content and its distribution of each growth ring in air dried wood specimens have been tested by using X-ray scanning densitometer .

  2. 气干材和溶剂置换材的边材渗透性均大于对应的心材渗透性。

    The permeability of sapwood of both air dried and the solvent exchange dried specimens were bigger than the heartwood .

  3. EDAX分析表明,气干材、水调湿材制备的木材/二氧化硅复合材料,二氧化硅存在于木材细胞壁中,硅的质量百分含量分别为4.11%、9.22%;

    EDAX analysis showed that silicon dioxide was found in cell wall of wood for the air-dried and moistening pretreatment of wood , and in both cell wall and cell cavity for the water saturated wood .

  4. 室干材的尺寸稳定性、变形程度及力学性能均优于气干材;

    Property indexes such as dimensional stability , deformation degree , hardness and cleavage strength were tested and the results were analyzed .

  5. 结果发现,2组间湿材含水率均达到210.0%以上,气干材含水率约为13.0%;

    The results show that both of the MC of wetwood are more than 210.0 % , and air-dry MC are both about 13.0 % .
