空中

EADS is the European Aeronautic Defense and Space company, the parent of air bus.

EADS就是欧洲航空防御和空间公司，空中巴士的制造者。

EADS is the European Aeronautic Defense and Space Company, the parent of air bus Airbus .

EADS是欧洲的航空航天防御公司，是空中巴士的前身。

EADS is the European Aeronautic Defense and Space Company , the parent of Airbus .

后者是空中巴士的起源——欧洲航空防备和空间公司。

The conventional aerotriangulation solves only the elements of exterior orientation 〓ω,κ, X〓, Y〓, Z〓 of photo, whereas the elements of interior orientation x〓, y〓, f of aerial camera are often determined in the laboratory. As the laboratory methods can not take into full account the actual conditions in aerophotography, large deviations often occur.

长期以来，航摄仪的内方位元素主要在实验室采用物理方法检定，而像片的外方位元素则主要依靠空中三角测量和大量地面控制点间接解求。

Can you see an aeroplane in the sky?

你看得见空中的飞机吗？

The composition and function of tethered aerostat system is introduced on the basis of analyzing the overall requirements of tethered aerostat system –bome radar.

系留气球是一种应用广泛的空中平台，本文在讨论搭载雷达系留气球系统总体需求的基础上，介绍系留气球系统的组成和功能，总结系统总体设计中涉及到的关键技术，并对关键技术的解决措施进行分析。

Tethered aerostat doesn't have dynamic devices, and it suspends on the upper space by buoyan -cy and cable' pull.

系留气球不具有动力装置，靠浮力和缆绳的拉力作用悬浮于高空中。

This paper first analyses the stress acting on the cable by means of tiny segment analytical methods, establishes cable's stress equation, and finds out the relation between the tethered aerostat's position and its stress acting by cable; then, based on the momentum and moment of momentum theorem, the longitudinal nonlinear dynamic equation is established; Finally a numerical simulation of dynamic responses of the balloon and cable to gust are carried out.

本文首先通过微段分析法对缆绳进行受力分析，建立缆绳的受力方程，找出了系留气球在空中的位置同系留气球所受缆绳拉力的关系；然后根据动量和动量矩定理建立了球体的纵向非线性运动方程；最后通过数值仿真计算，对系留气球的纵向动态响应特性进行了分析。

One, control member it is empty pipe line of business the intelligence that control of the traffic in the most important resource sky is danger of a Gao Feng works, get information ceaselessly, the analysis evaluates trends, decisive make judgement decision-making, issue instruction information, deploy safe control interval to run medium aerostat at any time, handle all sorts of bolt in time special affection.

一、管制员是空管业最重要的资源空中交通管制是一项高风险的智力劳动，不断地获取信息，分析评估动态，果断作出判定决策，发出指令信息，随时为运行中的航空器配备安全的管制间隔，及时处理各种突发特情。

Then I spoke to a seargent at Air training Command headquarters at Randolf AFB in San Antonio.

后来我在圣安东尼奥的Randolf基地的那个空中训练司令部的中心碰到个士官和他说起这件事。

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
