服务经理只说，他没有看到不定时皮带就被一辆汽车就超过15万英里它具有带，也从未改变。

The results show that:(1) The penetration resistance of functionally graded layered armour made of metal Matrix Composites is better than that of the Aluminum plate;(2) The penetration resistance of the functionally graded layered armour whichlay_up is 0%/57%/0%/26%/0%/12%/0% is the best;(3) The resistance penetration of the the functionally graded layered armour can be greately promoted through optimizing the lay_up and volume fraction of the reinforced particle;(4) The functionally graded armour in which the particles distribute continuous has better behavior of resistance penetration when the volume fraction of the reinforcements are constant;(5) The higher volume fraction of the reinforcements at the surface of FGM and the more non-homogeneous the reinforcements distribution, the higher thesurface Youngs Modulus and the flow stress are;(6) The behavior of penetration resistance of the functionally graded armour in which the particles distribute continuously is better than that of homogeneous steel plate;(7) The functionally graded armour provedes a important approach for the optimization and design of the resistance penetration;(8) The numerical results of simulation of the bird striking the aircraft structureshow that the finite element model of the balance leg is effective;(9) The numerical results show that the structure internal force is relative largewhen the bird strikes the top of the balance leg;(10) The process of the birdstrike is thaf.after the bird penetrting through the front skin of the balance leg and striking the front beam,the bird is broken up in three parts.

经过本文所进行的数值模拟后我们发现：(1)在层状梯度装甲板的抗侵彻过程中层状功能梯度板比铝板的抗侵彻性能好；(2)在层状梯度装甲板的抗侵彻过程中铺层顺序为0%/57%/0%/26%/0%/12%/0%的功能梯度装甲板的抗侵彻性能最好；(3)通过优化组合层状梯度板的铺层顺序以及增强颗粒的含量可以大大改善梯度板的抗侵彻性能；(4)当SiC颗粒体积含量一定时，增强颗粒连续分布的功能梯度板表现出了优越的抗侵彻性能；(5)增强颗粒连续分布的功能梯度板表面SiC颗粒体积含量越高，分布越不均匀，表面的弹性模量就越高，屈服应力就越高；畜此工业大学硕士研究生学位论丈(6)增强颗粒连续分布的功能梯度装甲板比匀质钢板表现出良好的抗侵彻性能；(7)功能梯度装甲板为整个抗侵彻性的优化设计提供了重要的途径。

As an added bonus, regular exercise encourages the body to produce extra synovial fluid.

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。

A clear Matsudaira's Storm-petrel I saw in Taidung in Aug 2004 was uniform mid-pale brown above; noticeably broad-winged; and flew with slow, steady wing action in a direct path (not "charging about" like Swinhoe's).

我2004年8月在台东观察到一只清楚的日本叉尾海燕，看起来是均匀中度灰棕色，有醒目的宽翼，而且以缓慢、稳定的振翅方式朝直线路径前进(不像黑叉尾会不定时转弯， S 型蛇行前进)。

And estimated highly on their quality in world market of America, Asia, Europe and like places, and as manufacturing industrial control parts firm of terminal block, micro cam, toggle switch, relay, relay-socket, lamp, panel-control switch.

Most electronic products are targeted at the high-end car users, so this trend, A car engine design regular starter for a lot of need and market potential.

而现在汽车市场上有很少相关的电子设备，且价格昂贵，大多数电子产品都针对高端的汽车用户，所以在这种趋势下，设计一款汽车发动机定时启动器有很大的必要性和市场潜力。

His trademark is an amber holder and his proudest possession appears to be his cigarette case with built-in timer and lock.

他的&注册商标&是一个琥珀烟嘴，而他最引以为自豪的财产似乎就是他的烟盒——装有内插式定时器和锁。

Hr, map and smaf were recorded at the time points of 1 h before clipping, right shock time after removing the clip, 1 and 2 h after removing the clip respectively.

实验期间分别于夹闭前(-1 h)、松夹后休克即时(0 h)、松夹后休克l h、2 h定时记录心率(heart rate，hr)、平均动脉压(mean arterial bloodpressure，map)及肠系膜上动脉血流量(superior mesenteric artery blood flow， smaf)。

Based on the CMMB system signal model, symbol timing synchronization error, sampling clock offset error and carrier frequency offset error are analyzed carefully.

在建立CMMB系统信号模型基础上，分析了符号定时同步误差，采样钟偏移误差，载波频偏误差对CMMB系统性能的影响。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
