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。

The patient showed atrophy in frontal and temporal lobe on regular MRI, significantly reduced amount of Nacetyl aspartic acid、cholineand creatinecompared with contralateral on MRS , remarkably decreased blood flow in the left temporal polar and front part of fontal lobe compared with contralateral on PWI. There were decreased association fibers between Broca and other regions meanwhile no association fibers were found between triangular area and wernicke region on DTI. The fibers projecting to opercular part of frontal lobe via archiform fibers were lessened. The mean FA and fibers of Broca and Wernick regions were less than that of the healthy subjects.

Hepatic chymase concentrations in S3 and S4 cases were greater than in S1 and S2,〔53+54=(31.3±24.6)ng/mg vs. S1+S2=(5.7±4.8) ng/mg, P.01〕. Cells immunoreactive for chymase were seen throughout portal areas and intralobular sinusoidal walls, largely colocalizing with fibrosis. Chymase appears to be involved in hepatic fibrosis in chronic hepatitis.

慢性肝炎纤维化分期重的S3和S4患者，其肝组织中Chymase浓度〔S3+S4=(31.3±24.6)ng/mg〕明显高于纤维化轻的S1和S2患者〔S1+S2=(5.7±4.8)ng/mg〕，P.01；免疫组化染色结果，Chymase标记的肥大细胞主要分布于纤维化旺盛的汇管区与类洞壁，其分布与纤维化部位相一致，且肝组织中Chymase浓度高的患者，其肝组织内Chymase标记的肥大细胞分布增多推测肝组织中Chymase浓度可能与慢性肝炎肝纤维化关系密切。
