The results show that the microscopical pore structure of the three dimensional orthogonal woven carbon fabric structure perform is composed of body-centered cubes which arranged periodically at spaces. The net structure and shape of the pores of perform are determined by the size and proration of the fasciculus diameter, which are key factors influencing the gaseous permeability and final density of composites. Once the proration of the fasciculus diameters of different directions is determined, the trend of diversification of the permeability followed by pore rate during CVI process and the density of composites are stated, and the permeability increases with the increase of the fasciculus diameter.

研究结果表明：三维正交结构炭纤维预制体的宏观孔隙结构在空间上可以看成是由呈周期性排列的体心立方"晶胞"构成； X ， Y 和 Z 3个方向纤维束直径大小及比例关系决定三维正交结构炭纤维预制体宏观孔隙网络的结构和形状，也是决定反应气体在孔隙中的比渗透率和复合材料最终致密度的重要因素；当 X ， Y 和 Z 3个方向纤维束直径的比例关系一定时，不同预制体在CVI增密过程中比渗透率随孔隙率变化的趋势相同；复合材料的最终致密度一定；比渗透率随纤维束直径增大而略有增大。

Because of the decrease of the resin flow and the reduction of fiber bundle voids, the penetrating process of the matrix is a limited process. Increasing impregnating time can't guarantee to get complete penetration.

由于树脂受力的衰减和纤维束孔隙率的减小，树脂在纤维束中的渗透是一个有限过程，延长浸渍时间不能保证树脂在纤维束中的完全渗透。

The same results were observed in the brain of the unilateral pyramidotomy group above the level of the transection site. Below the level of the transection site, the BDA positive fibers were seen in the right pyramid of medulla oblongata and the left dorsal funiculus of spinal cord, but the BDA positive fibers in the left pyramid of medulla oblongata and the right dorsal funiculus of spinal cord were not seen.

锥体束横断损伤大鼠在损伤部位以上可见双侧对称的BDA阳性纤维束，损伤平面以下在右侧延髓锥体和左侧脊髓后索中见有BDA阳性纤维束，损伤侧锥体和右侧脊髓后索中未见有BDA阳性纤维束。

For wool fibres, Sirolan TENSOR can supply fibre bundle tenacity and bundle extension , but has some limitations on the analysis of the measured tensile curves of fibre bundles.

采用束纤维强伸性测量方法能够得到羊毛纤维束比强度与纤维束伸长率，但在分析纤维束强力曲线时存在局限性。

From the point of microstruction,bamboo volume fraction of bundlesheath,single bundle sheath area,fiber width,cell wall thickness increase withthe growth of age,fraction of cell wall changes like density,increases with thegrowth of age,the 2 age-degree bamboo is the biggest.The reason why 2 age-degree fraction of cell wall more than 3 age-degree bamboo is the former has thegreater fraction of parenchyma;1 age-degree bamboo has the greatest fiberlength,fiber length and width ratio and vessel length.The difference in bamboofiber length,vessel length and width among other age-degrees is not distinct.

从构造角度来说，竹材的纤维束比量、单个维管束纤维束面积、纤维宽度、胞壁厚度随着年龄的增大而增大，胞壁率随年龄变化规律与密度相似，随年龄增大而增大，以2度竹最大，2度竹胞壁率比3度竹大主要由于薄壁组织比量较大所致；纤维长度、纤维长宽比、导管长度以1度竹最大，其它年龄纤维长度、导管形态变化不明显。

In this paper we proposed a hypothesis of difference fiber volume fraction and presented expressions respectively. The fiber volume fraction of unit cell is not equal to that of each lamina, which need calculate eachly. The paper also advanced conception of weighted average of three cell's stiffness.

本文提出了差别纤维体积分数的假设，各个纤维束的纤维体积分数与单胞的纤维体积分数并不相等，需要分别进行计算，并分别给出了各纤维束的纤维体积分数计算式；还提出了三单胞弹性模量按比例叠加的思想，并给出了比例计算式，计算出了结果。
