| 摘 要： | 利用CT技术无损检测实木地板、杨木重组木地板以及毛竹重组竹地板的内部结构，并分析了三者的密度变异特征。结果表明:密度变异重组木地板＞重组竹地板＞实木地板；杨木重组木地板从表面到背面的剖面密度分布（VDP）呈现小幅下降后大幅上升的趋势，而实木地板与毛竹重组竹地板VDP无明显变化规律。CT技术能用于地板结构与密度的检测与分析，并将在木质地板质量无损检测以及重组材地板工艺优化研究中产生积极影响。

| Abstract: | Structure and density distribution of wooden floor to a large extent determine its physical and mechanical properties.The internal structure of three kinds of wooden floors,including solid wood,poplar scrimber and moso bamboo scrimber,was detected using computed tomography(CT),and their density characteristics were also presented in this paper.The density variation was poplar scrimber > moso bamboo scrimber > solid wood flooring;and VDP of poplar scrimber presented substantial upward trend after declining s... |
