在飞行中的

When the burnt gases run over the exhaust nozzle with limited length, the dissociation energy can not be released fully.

这些解离能在长度受限的尾喷管中难以充分复合形成推力，使冲压发动机性能随飞行马赫数增大而急剧下降。

When we Superluminal flight in space and time, we can feel a long time.

当我们以超光速在时空中飞行时，我们就可以感受到时间的漫长了。

IN A FFEW MINUTES OUR PASSENGER PLANE WILL BE FLYING IN THE STRATOSPHERE.

将来进行时几分钟后们的客机将在同温层中飞行。

Supersonic speed aircraft and guided aircraft missiles are subjected to rapid aerodynamic heating and rapid loading during their flight.

高速飞机及飞航导弹在飞行过程中受到气动力的快速加热和快速加载。

During the 1991 Gulf War, 80% of the Tomahawk cruise missiles launched by the U.S. forces hit their targets within 3 meters of the aim point after a 1,600km journey.

在1991年海湾战争时，美军发射的"战斧"巡航导弹中的80%在飞行1，600公里之后，在3米误差内击中了它们的目标。

If these errors go uncorrected, they become more and more exaggerated, and you miss your window of opportunity.

如果这些误差不更正，就会在飞船的飞行中不断扩大。你就会错过那扇"幸运之窗"。

Pictures and films were taken of flying saucers, or Unidentified Flying Object,as they are now called,seen in the sky

人们把在天空中看到的飞碟或不明飞行物拍摄成图片和影像资料。

In a situation such as when you don't have access to a printer, but must print out some transient documents such as booking confirmation for concert, flight or train tickets, or receipt for online purchase, or you simply want to keep a soft copy of the documents in unmodifiable format so that the file can later be printed elsewhere, you can make sure of MS Office Document Image Writer by printing to this virtual printer which will subsequently create a file with .

在这种情况如当您无法访问到打印机，但必须打印出一些短暂的文件，如预订确认为音乐会，飞行或火车票，或收据，线上购买，或者您只想保持软复本该文件在unmodifiable格式，使档案稍后可以印在其他地方，你可以作出肯定的MS Office文件中的形象，作家通过打印到这个虚拟打印机，这也将随之建立一个档案。

On the next Shenzhou flight, that will include guiding the unpiloted spacecraft to the Tiangong 1 target for China's first orbital docking.

在接下来的神舟飞船飞行中，任务将包括指引无人驾驶飞船与"天宫一号"完成中国首次轨道对接。

Owing to the inherent unstability and high degree of coupling in a helicopter, the aircraft needs to be controlle...

由于直升机具有不稳定和高度耦合等特性，故其在飞行全过程中的任何时刻都需要进行控制。

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。
