Based on the structural model of tracheid from Bolton and Petty,the flow-resistor of tracheidis assumed to consist of four components in series.

设若一个管胞的流阻为Rg，管胞腔的流阻为RL，纹孔系统3部分的流阻分别为RPA、RBT和RMo；又，在某一个纹理方向上管胞纹孔的数目是N，纹孔膜的微孔数目是NM，则管胞在该纹理方向上流阻的数学表达式为

The number of elementsin this flow-resistor network can be determined by the tracheid length,radial diameter andtangential diameter of tracheid and the dimension of specimen.

根据Zimmermann有关实验结果以及气体在针叶材中流动的路径，气体在试件内的流动通道分成为不同的区域，气体将不会在这些区域之间流动，即各区域间的流阻不相连接；且这样的区域在三个纹理方向的管胞数目相同都等于管胞在试件纵向排列的数目。

Flow cytometry analysis was used to evaluate cells surface antigen expression and cells binding Ulex europaeus agglutinin-1 of the early and late clones in group B was detected by direct fluorescence staining.
