在飞行中

Five days had passed when a partial clearing allowed them to see the wideextending ocean beneath their feet, now lashed into the maddest fury by thegale.

五天以后他们才从云隙中看到下面的一片汪洋大海。在飓风的推送下，气球以惊人的速度飞行着。

In Ufology, any extraterrestrial contact initiated by humans is known as a Close Encounter of the Fifth Kind.

在不明飞行物学中，人类与外星任何形式的接触都被称为第五类接触。

This passage, from the angle of rotating mechanics, analyses the effect that the precession effect of the propeller and engine rotor has on flying qualities and operation qualities among giant turboprop airplanes.

从转动力学的角度，分析了在大型涡轮螺旋桨飞机中，螺旋桨和发动机转子进动效应对飞机飞行品质和操纵品质的影响。

In its maiden flight last August, WASP flew continuously at 30 mph for 1 hour, 47 minutes.

在 8月的首航中，&黄蜂&以30英里/小时的速度连续飞行了1小时47 分钟。

Tests with artificial stars have Proved that certain night-flying birds are able to follow the stars in their long-distance flights .

用人造卫星作的测试证明，某些夜间行进的鸟在长途飞行的过程中能够追寻星星的方向。

Of these missions, 599 were close support—468 for the 1st Marine Division, 67 for the ROKs, 56 for the 7th Infantry Division, and 8 for the 3d Infantry Division.

在这些飞行任务中，599个是近距离支援任务——其中468个是支援陆战1师，67个是支援南朝鲜军，56个是支援第7步兵师，还有8个是支援第3步兵师。

Experimental investigations on the combustion process of a liquid hydrocarbon fuel ed scramjet, ignited by hydrogen pilot flame, and with four different inlets, were conducted in free-jet tests, which simulated the fly conditions of Ma=6 and H=25km.

在模拟飞行马赫数Ma=6，高度25km条件的液体碳氢燃料超燃冲压发动机自由射流试验中，对比研究了4种不同进气道，不同燃烧室入口条件下模型发动机的点火与燃烧性能。

Aerial view taken from one of VMO-6's light observation aircraft, flown by 1stLt John D. Cotton, shows the power station, the pipes or "penstocks" that carried off the water, and the precarious nature of the road occupying a thin shelf cut into the precipitous slope.

这张是从VMO-6飞行中队的轻型侦察机上拍摄的航空照片，飞行员是约翰·D·卡顿中尉，照片中是一个水电站，巨大的输水管用于输送发电后的水流，还有借着地势在陡峭山壁上开凿出来的窄窄的公路。

"We conducted research with the chip while we were flying in parabolas over the Gulf of Mexico, going from two times Earth's gravity to zero gravity again and again," he said.

他说，使用该芯片，即使在墨西哥湾上空进行抛物线式飞行时，即一次次从两倍重力到失重状态的过程中，我们也可以进行我们的研究工作。

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。
