摘要
参照木材流体渗透性相关理论和研究方法,首次测量了单叶省藤和黄藤的节间和节部纵向气体渗透性。结果表明:单叶省藤的节间渗透性优于黄藤的节间渗透性,单叶省藤节部渗透性也好于黄藤节部渗透性。总体上单叶省藤和黄藤的节间渗透性分别稍高于节部渗透性,但部分藤节部的渗透性大于藤节间。单叶省藤和黄藤节间和节部的渗透性从基部至梢部都呈不规则变化状态,渗透性都明显高于木材和毛竹。单个藤种株与株之间的渗透性也有一定的差异。
The gas permeability of internode and node of Calamus simplicifolius and Daemonorops margatitae in the longitudinal direction was measured and analyzed for the first time with the relevant theories and research approaches for the fluid permeability of wood. The results showed that the permeability of intemode and node of C. simplicifolius were respectively higher than the permeability of internode and node of D. margaritae. In general, the permeability of internode of C simplicifolius and D. margaritae were a little higher than the permeability of the node, and the permeability of some nodes are however bigger than the permeability of the corresponding internodes. The permeability of C simplicifolius and D. margazitae were changed irregularly from bottom to top, and are higher than that of wood and Phyllostachys heterocycla var. pubescens. There is a little difference in permeability among strains.
