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 results show that dynamical ductil-ity dominated final velocity of fragments. During tube expansion, the shear fracture appears preferentially a-long the adiabatic shear bands under positive stress, so the adiabatic shear band determines the size and shapeof fragments. Though the fragmentation behaviour of medium carbon Si - Mn bainific steel is close to that ofsteel 50SiMnVB, medium carbon Si - Mn bainitic steel is an ideal candidate material for the tubular bombs be-cause it is better in dynamical ductility, which can enable the tubes to gain high speeds before fragmentation.

结果表明：材料动态塑性是决定破片最终速度的主要因素；圆管膨胀时外表面形成以剪切为主的裂纹，并向内扩展，接近内表面的绝热剪切带伴随着圆管的膨胀而扩展，并未出现失稳现象，但在正应力的作用下成为优先的断裂通道、决定破片的尺寸和形态；中碳Si-Mn贝氏体钢与50SiMnVB钢的破碎性能相近，但贝氏体钢动态塑性很更好，破碎前的膨胀量较大、更有利于提高破片初速，是弹箭比较理想的候选材料。

According to what the writer has known in the market on DC,the change of focal distance is a very important factor in quality of camera ,and which decides the price of the DC.

根据笔者在DC市场上了解，变焦倍数大小是决定数码相机好坏的十分重要的因素，变焦倍数的大小同样决定数码相机的价格，国产相机技术落后，在市场上几乎找不到有光学变焦功能的国产DC。

NEW YORK Dec 18 - The extent of tinnitus loudness and distress contribute to tinnitus seerity, and seeral factors determine the extent of loudness and distress, such as ertigo, hyperacusis and coexisting hearing loss, German inestigators report in the December issue of the Archies of Otolaryngology -- Head and Neck Surgery.

纽约12月18-德国研究者发表在耳鼻喉科学分册——头颈外科学12月刊上的文章提到：耳鸣响度和痛苦的程度决定了耳鸣的严重性，有很多因素决定了响度的大小和不适的感觉，比如说眩晕，听觉过敏还有并发的听觉下降。

The fragmentation of melt droplet is a key factor to predict the damage degree of fuel coolant interaction accident,which determines the final ratio of internal energy transferred to power.

熔融液滴的细粒化是决定燃料与冷却剂相互作用破坏后果的关键过程，它决定最终的热能与动能的转化比，是预测事故后果的重要因素之一。

These factors will interact with the degree of interrelatedness of technology within enterprises in that industry to determine the degree of competitiveness within an industry, and, in turn, determine whether information systems can be used to erect barriers to potential competitors or to encourage

这些因素将会由於技术的相关程度在企业里面在那种工业中互相影响来在一种工业里面决定竞争力的程度，而且，依次，决定是否资料系统能被用竖立对可能的竞争者的障碍或鼓励合作的利益。

It is found that in fluenc in g judge choos in g penal category by judicial procedure and crim in al charges in traffic, booty and larcener 's cases and by crim in al charges in drug cases.

从研究分析中发现，影响法官选择刑罚种类因素，在交通、赃物及窃盗案件，主要由审判程序及罪名所决定，毒品案件则由罪名决定

If a country has decided to do something, the support from nationals is a principle factor.

当一个国家决定一个行动，国民的支持是决定的因素。

The APW in summer is less than 25 mm which is the least limit value of monsoon areas.This means that Xinjiang is not affected by monsoon.The geographic distribution of APW is adverse with that of precipitation,videlicet,higherAPW values corresponding to lower precipitation values.With the effects of westerly winds,the APW mode presents as an uniform change within Xinjiang area and has a stable distribution.It is very different from Xinjiang rainfall mode which changes a lot spatially.As mentioned above,there is no obvious change during 1961～2000,this indicates that APW is not a dominant factor determining precipitation,it is the result of dynamic condition,water vapor convergence and other causes.

APW的地理分布与实际降水量分布相反，其最大区域却为降水量最小区，受西风带影响，新疆APW模态主要表现全疆一致变化，分布稳定，与降水模态分布差异性大有显著不同，且近40年来无显著变化趋势，表明决定新疆降水差异的根本原因不在于水汽的多少，而是由降水产生的动力条件、水汽辐合和其它因素差异决定的。
