空中的

When it's dark, in a vacuum, if a person shines a beam of light straight across your eyes, you won't see it.

当黑暗时，在真空中，如果有人将一束光直射进你的眼睛，你就看不见它。

A bird's eye view from the air, as if it were a pearl of the Thames.

从空中鸟瞰，它如同泰晤士河畔的一颗珍珠。

The first design example is to generate program code for image processing controller to control picture file output and the second design example is a GPS satellite C/A code generator to generate the C/A code of GPS satellites. C/A code can be used to recognize GPS satellite number in GPS system.

最后我们使用两个例子来验证本工具，一个为影像处理控制器，其功能为控制图档输出功能，另一个为GPS卫星C/A码产生器，其功能在於能够产生太空中GPS卫星所使用的C/A码信号，C/A码在GPS系统中被用来识别GPS卫星编号。

Wehter you feel a great volume of sound , fluttering in the air look for the luck which not ought to lost in haste?

二 你是否感觉到一阵风，飘在空中寻找那一份不该匆匆错过的缘？

A quantity of small objects flying through the air.

较小的物体从空中喷出散落。

A device and method for preparing compound nano fiber endless tow, which contains feeding material liquid to pair of electric spinning nozzle on frame, each nozzle respectively applied with high dc voltage with opposite polarity, each pair of nozzle jetting out nano fiber with opposite electric charge, said nano fiber attracting and colliding each other to form compound nano fiber, then forming nano fiber endless tow after drawing and stretching, the first opposite set pair of electric spinning nozzle jetted compound nano fiber endless tow is stretched down and used as acceptor which covered by the nano fiber jetted by second pair of nozzle an d forming two layers of compound nano fiber endless tow after drawing and stretching, in turn to get multilayer compound nano fiber endless tow after drawing and stretching by godet roller.

复合纳米纤维长丝束制备装置及其制备方法是一种简单、高效电纺制备纳米纤维长丝束的方法，其步骤为将料液输送给支架(3)上的电纺喷头对(1)；喷口相向的电纺喷头对(1)的每个喷头分别施加相反极性的直流高电压；每对相向喷口喷出分别带相反电荷的纳米纤维，并在空中相互吸引、碰撞形成复合纳米纤维，经牵引、拉伸后形成复合纳米纤维长丝束；第一对相向放置的电纺喷头纺丝形成的复合纳米纤维长丝束向下拉伸，并作为接受体与第二对电纺喷头喷出的分别带相反电荷并相互吸引的纳米纤维在空中相遇，被第二对电纺喷头喷出的纳米纤维包裹，经牵引、拉伸后形成两层复合纳米纤维长丝束；依次类推，最后经导丝辊对(2)牵引、拉伸后得到多层复合纳米纤维长丝束。

The theoretical and computational results show that an important reason resulting in eccentric wear of the inner cylinder and the pumping rod lies in the nonuniformity of the stress distribution on the outwall of the inner cylinder which yields excentralization effect of the pumping rod when swabbing fluid flows in eccentric annuli with the pumping rod moving axially in a well.

在实验上，通过不同重量百分比浓度的HPAM水溶液在内管做轴向往复运动的偏心环空中非定常流实验，把由理论公式算得的时间平均流量与实验中测得的时间平均流量做了比较，验证了本文数值计算幂律流体在内管做轴向往复运动的偏心环空中非定常流方法的正确性；上述的理论与计算表明，抽油机井杆管偏磨的一个重要原因是，在聚驱工况下，抽汲液体在抽油杆做轴向运动的井筒中流动时，抽汲液体作用在抽油杆外壁上的压力分布的不均匀性所引起的抽油杆在井筒中的偏心效应。

And when the evening mist clothes the riverside with poetry, as with a veil, and the poor buildings lose themselves in the dim sky, and the tall chimneys become campanili, and the warehouses are palaces in the night, and the whole city hangs in the heavens, and fairy-land is before us——then the wayfarer hastens home; the working man and the cultured one, the wise man and the one of pleasure, cease to understand, as they have ceased to see, and Nature, who, for once, has sung in tune, sings her exquisite song to the artist alone, her son and her master——her son in that he loves her, her master in that he knows her.

当傍晚的薄雾笼罩着河岸，一切都充满了诗意，就像蒙上了一层薄薄的面纱，灰暗的房子渐渐消失在暗淡的天空中，夜里，高耸的烟囱变成了钟楼，仓库变成了华丽的宫殿，整个城市似乎是悬浮于空中，仿佛置身于仙境一般—旅行者匆匆的回家了，行人，骚客，聪明人，快乐的人，开始不明白了，因为他们停止了观察，自然曾经用她的旋律唱着歌，优美动听的音乐唱给了孤独的艺术家--一个以为爱着自然的孩子，懂她的艺术大师。

In the second part of the paper, the sport techniques of the flight elements was analysised in-depth theoretically by the movement technical structure:①the giant swing was first analysised in mechanics by applying the Kane's method, the dynamic equation of 5-link multi-body model was established, and the computer simulation software of the giant swing on the high bar was developed.

其次，作为单杠上飞行动作系统性研究的另一主要方面，本论文对飞行动作一般技术结构中的各技术环节进行了深入的理论分析：①着重对飞行动作准备阶段的回环运动技术进行了动力学分析，主要采用了多体力学理论中的Kane方法，建立了5环节人体回环运动的动力学方程，并应用计算机数值仿真技术研制开发了用于回环运动动力学分析的数值仿真软件，进而以动作实例对回环运动进行了数值仿真与误差分析，其所得到的数值仿真结果能够满足对人体回环运动的动力学分析和仿真要求；②对于飞行动作的撒手技术环节，本论文从人体环节相对运动角度，来分析撒手时人体质心的运动以及撒手时角动量参数，并列举了几种飞行动作撒手技术的基本力学指标；③关于飞行动作的空中技术，论文在总结了空翻转体动力学机理的研究成果基础上，对人体空中运动定量化问题进行了一般性描述，并进一步应用刚体动力学理论，着重建立起了描述空翻与转体技术之间定量化的关系，讨论了空翻转体运动的稳定性及其运动模式的转换问题，它对于定量地评定空翻转体技术以及今后对空翻转体动作进行数值仿真都具有理论上和实践上的重要意义；④关于飞行动作再握技术环节，本论文避免了以再握瞬时性的力学参数指标来描述再握技术特征的简单化途径，提出以再握下摆与回环下摆相对比的方法来研究再握技术，并以飞行动作再握技术的具体实例进行了对比分析，表明再握下摆技术相比回环下摆技术有着相当的困难性和复杂性，运动员对再握下摆过程中各环节的相对运动实施有效的控制，是连接高难动作以及顺利流畅地完成成套动作的关键。

While the most descriptive accounts of the Gardens come from Greek historians such as Berossus and Diodorus Siculus,Babylonian records stay silent on the matterTablets from the time of Nebuchadnezzar do not have a single reference to the Hanging Gardens,although descriptions of his palace, the city of Babylon, and the walls are foundEven the historians who give detailed descriptions of the Hanging Gardens never saw themModern historians argue that when Alexander's soldiers reached the fertile land of Mesopotamia and saw Babylon, they were impressedWhen they later returned to their rugged homeland, they had stories to tell about the amazing gardens and palm trees at MesopotamiaAbout the palace of Nebuchadnezzar About the Tower of Babel and the zigguratsAnd it was the imagination of poets and ancient historians that blended all these elements together to produce one of the World Wonders

虽然对花园最详尽的记述是出自Berossus 和 Diodorus Siculus等希腊历史学家笔下，但巴比伦的历史记录却对此事只字未提。尽管在尼布甲尼撒时期存留下的各种书写板上发现了对他的宫殿、巴比伦城以及巴比伦的城墙的种种描述，但这些书写板上却没有一处提到过空中花园。甚至那些对空中花园进行过详细描述的历史学家们也从没有亲眼目睹过它们。现代历史学家争论说：当亚力山大的士兵们到达了富饶的美索不达米亚地区并看到了巴比伦时，他们深为所震撼。当他们后来回到崎岖不平的家乡时，带回了有关美索不达米亚的令人惊叹的花园和椰子树……、有关尼布甲尼撒的宫殿……以及有关巴别塔和金字型神塔的各种故事。是诗人和古代历史学家的想象力把这所有的元素混合在一起制造出了世界奇观之一。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
