摘　　要：参照木材流体渗透特性相关理论和研究方法,对大型丛生竹种———龙竹竹材的纵向气体渗透性进行了测定和分析,结果表明预处理方法和含水率对竹材纵向渗透性有显著影响。预处理可提高竹材气体渗透性,水煮预处理试件的渗透性优于汽蒸预处理试件的渗透性;随竹材试件含水率降低,竹材纵向气体渗透性增加。这些结论可为竹材防霉处理、染色处理、防火处理等改性处理提供有益的参考。The research on the longitudinal direction gas permeability of bamboo was measured and analyzed with the relevant theory and research approaches of permeability of wood, The results indicated that the pretreatment methods and M, C, of bamboo had significant effects on the permeability behaviors, The permeability could be improved better by boiling water treatment than by steam one and decreased with increased of the moisture content of sample as well. Therefore, they would be useful for wood modification.
