在飞行中的

If you're in an aerobatics airplane or you're doing aerial-combat maneuvers in a jet fighter or you're sailing a boat in an important race, you really don't think about the problems back at the office.

如果你驾驶一架特技飞行飞机，或驾驶一架喷气战斗机在空中作各种特技动作，或者在一场重要的比赛中驾驶一艘小船航行，你就会完全忘记工作中的烦恼。

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。

Huanjiang pterosaur fossils from that we can understand that Huanjiang pterosaur wing is an original hand-long class, the wings expand to more than two meters long, can fly by gliding in the air, but also on the ground running, swimming in the lake.

由环江翼龙化石我们可以了解到，环江翼龙属原始的翼手龙类，翅膀展开来有两米多长，能借助滑翔在空中飞行，也能在地上行走，在湖泊中游泳。

In the farmyards,the chickens and even the pigs were too nervois to eat.Mice ran out of the fields looking for places to hide.Fish jumped out of their bowls and ponds.At about 3:00 am on july 28,1976,some people saw bright lights in the sky.The sound of planes could be heard outside the city of Tangshan even when no planes were in the sky.In the city,the water pipes in some buildings cracked and burst.but the one million people of the city,who thiught little of these events,were asleep as usual that night. At 3:42 am everything began to shake.It seemed as if the world was at an end!

在farmyards、鸡、甚至是猪太nervois吃老鼠跑出领域找地方躲鱼跳出他们碗和池塘大约下午3点在7月28，1976，有些人看到明亮的灯光在天空中能听见飞机飞行的声音以外的城市唐山，即使在没有飞机在天空中在这个城市里，这些水管破裂，burst.but一些建筑物的一百万居民的城市，这些事件，thiught很少像往常一样，晚上睡觉的时候。

A day after a dramatic splashdown and rescue, in which all 155 passengers and crew members of Flight 1549 escaped safely from an icy plunge into the Hudson River, investigators prepared to lift the mostly submerged aircraft from its resting spot in the water at Battery Park City.

一般是指宇宙飞船结束飞行后降落在海中，这片文章里空客CA320从Laguardian机场起飞后遭飞鸟撞击，飞行员凭借着高超的驾驶技术和沉着镇定，将飞机降落在Hudson河中，避免了一场灾难的发生。

Periodic fluid pulsation in aeroplane hydraulic piping could induce fluid-construction vibration and lead to fatigue damage. It is impossible to find the error sensor's optimization location because of the pressure standing wave, and the pulsation attenuation effect is not perfect when adopting pulsation attenuation at single point. For this reason, a distributed active control method of fluid pulsation was presented. To avoid stationary point in all aviation states, several fluid pulsation actuators and error pressure sensors were placed along the piping. The second fluid pulsation produced by actuators can counteract the primary pulsation brought by aviation piston pump and make the mean pulsation of whole piping minimum when adopting adaptive feed- forward control and the filtered-X least mean square algorithm.

针对飞机液压能源管路系统中的周期性流体脉动诱发流固耦合振动，导致管路疲劳损伤的问题，针对管路中存在压力驻波特性，在采用单点消振时寻找误差传感器最佳布局位置困难而引起脉动抑制效果不理想的缺点，提出了一种分布式流体脉动主动控制方法，即沿管路不同位置布置多个主动消振阀和误差压力传感器，在任意飞行阶段，避开压力驻波点，以误差压力传感器的脉动测量值为控制目标，采用一种针对周期脉动主动控制的自适应前馈控制法和多通道自适应滤波－X LMS算法，调整控制器参数，使主动消振器产生的次级脉动与管路中的初始脉动相互抵消，达到整个管路中的平均流体脉动最小的效果。

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

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。
