在飞行中

"We feel this really was a tremendous success for the project," added David Bushman, project manager for beamed power at Dryden."We are always trying to develop new technologies that will enable new capabilities in flight, and we think this is a step in the right direction."

"我们真的感到它是一个巨大的成功"David Bushman补充道"我们总是在寻求能在飞行动力中在原有的技术基础上获得突破，看来这一点我们是走对了。"

It is an important half hardware-in-loop simulation equipment, which is often used to simulate the aerodynamic torque load on the missile rudder or elevon actuators in the flight.

它是地面半实物仿真系统中的一种重要专用设备，用来模拟飞行器舵机在飞行过程中所承受空气动力力矩载荷。

We meet members of their families, particularly Marilyn Lovell, we follow some of the training, and then the movie follows the ill-fated mission, in space and on the ground.

我们看到了他们的家庭成员，特别是玛里琳。罗维尔，接着我们看到他们在训练，然后，电影循着霉运一步步逼近飞行使命，在太空中、在地面上。

But belongs to the air, travelling it may be six thousand miles to and from its northern nesting home, feeding its flown young as it flies

在空中十分自如，可以飞行6，000英里，可以飞往北方做窝的老家，再从老家飞回；一边飞一边喂养会飞的雏燕，甚至在顶风时也能在气流中滑翔，似乎气流在帮它前进。这些鸟对我们是有益的

It tires not nor does it boast of its power; but belongs to the air, travelling it may be six thousand miles to and from its northern nesting home feeding its flown young as it flies and slipping through a medium that seems to help its passage even when the wind is adverse.

燕子充分兼有这两类鸟的长处，它既不疲劳，也不炫耀自己的飞翔力；在空中十分自如，可以飞行6，000英里，可以飞往北方做窝的老家，再从老家飞回；一边飞一边喂养会飞的雏燕，甚至在顶风时也能在气流中滑翔，似乎气流在帮它前进。

Of the some 900 species of bats, more than half rely on echolocation to detect obstacles in flight, find their way into roosts, and forage for food.

在约900种蝙蝠中，一半以上依靠回一定位法探测飞行中的障碍物，寻找回巢的路线和用作食物的饲料。

The author best known for creating the Headless Horseman also created the iconic image of Santa flying in a sleigh. In his 1819 series of short stories, The Sketch Book of Geoffrey Crayon, New York native Washington Irving described a dream in which St. Nicholas soared across the sky in a weightless wagon. The stories became so popular they spawned a Christmas revival of sorts in the States, and even Charles Dickens is said to have credited Irving's work for inspiring his classic holiday tale A Christmas Carol.

以创作了无头骑士这一形象而著称的知名纽约作家华盛顿·欧文，同时也创造了圣诞老人在雪橇上飞行的形象在他1819年创作的短篇故事《Geoffrey Crayon的素描书》里，他描述了一个梦，圣诞老人在一辆失重的车里在天空中飞驰这个故事太受欢迎，以至于在全国掀起了一场圣诞热甚至狄更斯也表示，他是在欧文的影响下完成了他的经典圣诞故事-圣诞颂歌

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。
