Normal flying is faced with more and more serious menace made by bird - striking with increasing flying speed of aircraft and the economic loss is increasing year after year 随着飞机飞行速度的提高，鸟撞事故给飞机安全飞行造成了越来越严重的威胁，经济损失逐年增加。
Russian pilot : control ， unidentified aircraft detected . altitude 30 , 000 feet . it ' s fast ! estimated air speed exceeding mach 3 . bearing south . . . i ' m about to lose it 俄国飞行员：控制中心，发现不明飞机，高度30000英尺。它太快了，飞行速度超过3马赫，方向向南，我跟不上它。
The cometary and interstellar dust particles encountered by stardust were traveling ten times at speeds of around 20 kilometers ( 12 miles ) per second relative to the spacecraft 彗星和星际尘埃颗粒会以10倍于“星尘”的飞行速度，也就是大约20千米/秒的相对速度撞上“星尘” 。
Speed : a half - fiend has bat wings . unless the base creature has a better fly speed , the creature can fly at the base creature ' s base land speed ( average maneuverability ) 速度：半炼狱生物拥有蝠翼。除非其基础生物有更好的飞行速度，半炼狱生物能以其基础生物基本陆地速度的两倍速度飞行(机动力良好) 。
In order to adjust the amplitude and width of the stress impulse in targets , the dependence of velocity and impactor thickness , as well as the flatness area of the wave front in targets are discussed 讨论了靶中应力波幅度和宽度的调控方法、冲击器的飞行速度与厚度的相关性、靶中应力波的平面范围。
As the air speed came on , the plane slowly , slowly rolled out with heavy , serious vibration problems because that prop was still spinning with parts of it missing , obviously out of balance 随着飞行速度起来，飞机慢慢地、慢慢地翻转过来，但是颤抖剧烈，显然是因为那个已经失去一些部件的螺旋桨仍在旋转，失去了平衡。
People will follow the players and the movement of the mouse around changes location players just beneath the brain figures press the left mouse button on the enter the name of the game 人物会跟随玩家鼠标的移动而左右变化位置，玩家只需在下方人物的脑袋上按下鼠标左键不放蓄力时间越长武器的飞行速度越快到适合的时机放手。
It will attain a top speed of 390 miles per hour at an altitude of 6 , 000feet and a cruising speed of 350 miles per hour at 25 , 000 feet , and it will have a maximum range of 900 miles at 80 passenger miles per gallon 在6000英尺高度的最高飞行速度为390英里/小时，在25000英尺高度的巡航速度为350英里/小时，在每加仑燃油的客英里数为80时的最大航程为枷英里。
It will attain a top speed of 390 miles per hour at an altitude of 6 ， 000feet and a cruising speed of 350 miles per hour at 25 ， 000 feet ， and it will have a maximum range of 900 miles at 80 passenger miles per gallon 在6000英尺高度的最高飞行速度为390英里/小时，在25000英尺高度的巡航速度为350英里/小时，在每加仑燃油的客英里数为80时的最大航程为枷英里。
The engines would have variable nozzles , which would be fully opened on take - off and landing , so that the exhaust would be slow and relatively quiet , and narrowed when the aircraft was cruising , providing the necessary speed 引擎将配有大小可以调节的尾喷管：起飞和降落时会全部打开，这样喷气速度会下降、噪音也会更小；而巡航飞行过程中，尾喷管将变小以保证必要的飞行速度。
