In this paper,the condition that gas flow through wood in the pattern of linear flux wasdetermined from the theories of thermodynamics and fluid mechanics.The expression of flow-resistor of tracheids is reduced with the continuity equation and the equation of motion indifferential form.The flow-resistor network is constructed by means of the theory ofpercolation.The equivalent flow-resistor was evaluated by utilizing the real spacerenormalization approach.

本文根据针叶材管胞的解剖结构，运用孔隙介质流体力学的理论，导出了管胞关于气体渗透流阻的数学表达式；继而根据管胞纹孔在三个纹理方向上的连接特性，利用管胞流阻建立了一个描述针叶材三个纹理方向气体渗透性的三维流阻网络；然后运用实空间重整化变换的方法，求解试件流阻网络三个纹理方向的等效流阻，并由此计算试件相应的气体渗透系数；最后用我国南方常见的人工林马尾松木材试件进行渗透系数实际测量，与理论计算结果进行对比分析，以验证三维流阻网络及其理论的准确性。

The techniques for measuring Hevea laticiferous turgor pressure which have been reported are summarized. The commonly used three methods used for measuring Hevea laticiferous turgor pressure have their limitation in deep and systematic observation of the variation of Hevea laticiferous turgor pressure and are not involved in the study of the variation of laticiferous turgor pressure under the normal ethrel stimulated tapping system. A possibility of using an improved cell pressure probe method which has been recently established for other plants is discussed in accurate measurement of the real time variation of Hevea laticiferous turgor pressure.
