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。

It was wholly in the lower ice, but close against the upper, and was flattish, or perhaps slightly lenticular, with a rounded edge, a quarter of an inch deep by four inches in diameter; and I was surprised to find that directly under the bubble the ice was melted with great regularity in the form of a saucer reversed, to the height of five eighths of an inch in the middle, leaving a thin partition there between the water and the bubble, hardly an eighth of an inch thick; and in many places the small bubbles in this partition had burst out downward,and probably there was no ice at all under the largest bubbles,which were a foot in diameter.

在气泡之下和周围已经结了一层新的冰，所以气泡是在两片冰的中间；它全部是在下层中间的，却又贴近上层，扁平的，也许有点像扁豆形，圆边，深四分之一英寸，直径四英寸；我惊奇地发现，就在气泡的下面，冰溶化得很有规则，像一只倒置的茶托，在中央八分之五英寸的高度，水和气泡之间有着一个薄薄的分界线，薄得还不到一英寸的八分之一，在许多地方，这分界线中的小气泡向下爆裂，也许在最大的直径一英尺的气泡底下完全是没有冰的。

This invention relates to a slider (11) for an optical data writing/reading apparatus (1), the slider carrying an optical lens (40) defining a focal point (42), the slider having a configuration such that, upon variation of the disk speed such as, for example, caused by a slider movement from an inner diameter to an outer diameter, the pitch angle varies owing to a pivot movement about a pivot axis which lies in a vertical plane through the focal point, the pivot axis preferably coinciding with the focal point.

本发明涉及用于光学数据写/读装置(1)的滑动器(11)，在该滑动器(11)上装有确定焦点(42)的光学透镜(40)，该滑动器具有这样一种结构，以便于在诸如滑动器从内径到外径运动造成盘速变化时，由于围绕位于经过焦点的垂直平面内的旋转轴的枢轴运动而改变倾斜角。

The method of interlaced calculation and the theory of relative crown diameter were developed based on the detection mechanism for fruiter crown diameter.

为实现果树仿形精确喷雾，需要检测果树冠幅，在分析果树冠幅检测机理的基础上，提出了隔行计算相对冠幅的方法。

The radical scavenging activity of Laminaria japonica pigments was studied by the DPPH2,2-Diphenyl~(-1-picrylhydrazylassay. The total pigments showed a strong DPPH radical scavenging activity of 65.819% with the concentration of 0.52mg.ml~(-1). The DPPH radical scavenging activity of fucoxanthin was 19.85% with the concentration of 0.27mg.ml~(-1). The antimicrobial activity of pigment in Laminaria japonica was studied by the method of round paper. The results showed that the pigment extracts have activity against Escherichia coli, Pseudomonas aeruginosa, Saricina flava and Saccharomyes cerevisia. The antibacterial activity of total pigments for Saccharomyes cerevisia was the strongest with an inhibition diameter of 18.9 mm; and the antibacterial activity of fucoxanthin for Saricina flava was also much significant with an inhibition diameter of 10.2 mm.
