Thomas Nugent and Jordin Kare, the company's principals, do not believe that a space elevator will be built any time soon, but they say the technology will find other commercial applications like powering small robotic aircraft.

该公司的负责人托马斯·金特和约尔丁·卡蕾不相信太空电梯将很快被建造出来，但他们说，这项技术将找到其他的商业应用，像动力支持的小型机器人飞行器。

A detailed investigation was conducted in this paper on the flow asymmetry and its influencing factors over an ogive slender body model, incorporated with surface pressure measurement, skin oil flow pattern visualization, hot wire dynamic signal acquasition and other relevant approaches, in a low turbulence wind tunnel.

现代先进战斗机和战木导弹常具有细长前体，大攻角条件下前体背风面会形成非对称涡结构，从而产生很大的侧向力和偏航力矩，这会严重影响飞行器的可操纵性和飞行安全。

With the development of Chinese spaceflight business, accuracy requirement of orbit determination for the spacecraft will be more and more high.

随着我国航天事业的发展，对空间飞行器的定轨精度要求越来越高。

In the space orbit environment, the continuous variation in temperature levels and the temperature gradients will...

在空间轨道环境下，由于冷热交变和较大的温度梯度的存在会引起空间飞行器部件产生一定的热变形。

When he landed, he drew a petroglyph on Second Mesa, showing a maiden (with the traditional "butterfly" hair arrangement) riding in a wingless, dome-shaped craft.

当他落地后，他在第二块岩石平顶绘一岩石雕刻，显示一位少女（具有传说的"蝴蝶"发型）骑在一没有翅膀的、圆形飞行器上。

Upon landing, he drew a petroglyph on Second Mesa, showing a maiden riding in a wingless, dome-shaped craft.

当他落地后，他在第二块岩石平顶绘一岩石雕刻，显示一位少女（具有传说的"蝴蝶"发型）骑在一没有翅膀的、圆形飞行器上。

The earliest "pilotless aircraft" were produced in 1934, and has some moderate degree of success.

最早的"无人驾驶飞行器"制作於 1934年，并在某种程度上的成功。

For purposes of comparison, the fastest man-made vehicle on earth, the Ulysses space probe, moves at a poky 27.4 miles/second.

用以比较的话，最快的人造飞行器Ulysses太空探险器，每秒才不过27.4哩。

The microstrip antennas has the volume small, the weight light, the structure stable, the section plane low, the feed way nimble, the cost low, is easy and the flight vehicle line, is altogether easy to produce the plan polarized wave and and so on the merit.

微带天线具有体积小、重量轻、结构稳定、剖面低、馈电方式灵活、成本低、易与飞行器共行、易产生线极化波和圆极化波等优点。

They flew "the world's first power-driven, heavier-than-air machine in which man made free, controlled, and sustained flight."

他们驾驶"世界上第一架动力驱使、重于空气的飞行器，进行了自由的、受控制且持久的飞行"。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
