在空中的

Power-law fluid is used to describe the Non-newtonian rheological property of the produced fluid in a polymer-driving well; the governing equations, boundary and initial equations of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially is established in bipolar coordinates system; formulas of instantaneous flow rate and stress distribution on the outwall of the inner cylinder of the unsteady flow of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially are established.

在理论上，用幂律流体模型描述了聚合物驱油井产出液的非Newton流变性；建立了双极坐标系下幂律流体在内管做轴向往复运动的偏心环空中非定常流的控制方程及边界条件和初始条件方程；建立了双极坐标系下幂律流体在内管做轴向往复运动的偏心环空中流动时瞬时流量和流体在内管壁上的压力分布计算公式。

The trajectory theory model of air target was made up according to its basic rule of flight control. A stochastic difference equation to model the air target movement in inertial frame coordinates was introduced.

根据空中目标飞行控制的基本规律，首先建立了空中目标航迹分布的理论模型，并在惯性坐标系中建立了基于随机微分方程的目标运动模型。

When stealth is no longer critical, the Lightning II can carry 18,000 pounds of ordnance on eleven underwing and fuselage stations for air interdiction and close air support missions.

当隐身问题不再需要考虑的时候，闪电II型能够在翼下挂架及机身下的挂点上携带18，000磅的武器执行空中遮断及近距离空中支援任务。

At times the night sky was illumined in spots by the distant glare of the dry reeds burning on the meadows and river-banks, and then, dark flights of swans, winging their way northwards, were suddenly lighted up by a silvery-pink gleam, and it seemed as if red kerchiefs were flying in the dark heavens.\

黝黑的夜空中，偶尔有草场和河边干芦苇的星点爆光一亮。天鹅展开双翼向北飞纵，蓦然一道银红辉过天鹅的黑影，有如绛色的华巾飘拂在夜空中。

Three Tactical Electronic Warfare Squadron 130 (VAQ-130) EA-6B PROWLER aircraft wait as an Attack Squadron 72 (VA-72) A-7E Corsair aircraft is refueled by an Air Force KC-135E Stratotanker aircraft to refuel while en route to targets in Iraq during Operation Desert Storm.

在针对伊拉克的&沙漠风暴&行动中，三架130电子战中队（VAQ－130）的EA－6B徘徊者电子战斗机等待着72攻击中队的一架A－7E海盗攻击机从空中补给加油机KC－135E进行空中加油，然后飞往攻击目标。

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.

夜幕降临，为河畔蒙上了一层轻纱，如诗般美丽、神秘。而那些毫不起眼的建筑物们则隐没在这昏暗的天空中，乍看之下，高耸的烟囱好似一座钟楼，破旧的仓库宛如宫殿般矗立于夜色之中。此时此刻，整个城市悬浮于半空中，如同仙境般展现在我们面前——接着，行人加快了回家的脚步；而工人、知识分子、智者抑或逍遥之人则驻足而望，停下了思考，故而，他们听不到自然那美妙绝伦的声音。大自然只为艺术家展现了歌喉，因为艺术家是她的孩子，她的主人——之所以这么说，因为孩子爱他的母亲，而主人则理解他的属下。

Europe began allowing limited air traffic to resume that day, giving hope to millions of travelers stranded around the world when ash from a volcano in Iceland disrupted air travel.

欧洲开始允许有限的空中交通恢复那一天，给希望在世界各地数百万的旅客滞留时，从冰岛火山灰烬扰乱空中旅行。

Alistair MacGrath has compared the Christian to a trapeze artist who has let go of one bar and is soaring through the air to catch the other bar swinging toward him. There's a moment when the trapeze artist is suspended in midair—caught in an act of faith.

麦格夫以高秋千杂技演员比喻基督徒，当杂技演员放开一边的杠飞跃空中，伸手准备去抓荡到他身边的另一条杠的那一瞬间，他正悬在半空中，这便是一个单靠信心维系的时刻。

Mt. Hakkoda-san also features fresh green plants in spring and orange- and gold-tinted leaves in autumn. There is a ropeway, on which you can enjoy the views of woodlands for 10 minutes, as well as other walkways where you can go for walks.

另外，在八甲田山，除观赏春天的新绿和秋日的红叶之外，还可以乘坐空中索道车一边欣赏眼底美丽的树海，一边作 10 分钟左右的空中漫游，或者漫步在散步小道上享受自然之美。

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。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
