在飞行中的

Found in the Solnhofen Limestone Formation in Bavaria, Germany, Archaeopteryx lithographica possessed developed wings that probably allowed it to fly for short distances.

这是在德国巴伐利亚地区的石灰石中找到的，始祖鸟的化石发现引起轰动，揭露它的翅膀允许短暂的飞行。

The motor will actively reduce cable tension peaks during the dynamic phase of the arrestment, and will accurately control both the hook load during arrestment and the final stopping position of the aircraft.

这种发动机将在阻拦的动态过程中有效降低阻拦索拉力的峰值，并对着舰钩挂上阻拦索的整个过程以及飞行最终停止的位置进行准确的控制。

A bluebottle path described by a particle, such as a sand grain in the rock, it would be more like that of a bluebottle buzzing round the room; it would be up and down, to and fro and from side to side.

假如我们真能看到诸如岩石中一个沙粒子的运动轨迹，那就像一只嗡嗡叫的绿头苍蝇在屋内飞行的轨迹，呈现出上上下下、来来回回、左左右右3种性质的运动。

If we could actually see the path described by a particle, such as a sand grain in the rock, it would be more like that of a bluebottle buzzing round the room; it would be up and down, to and fro and from side to side.

假如我们真能看到诸如岩石中一个沙粒分子的运动轨迹，那就像一直嗡嗡叫的绿头苍蝇在屋内飞行的轨迹，呈现出上上下下、来来回回的运动。

If we could actually see the path described by a particle, such as a sand grain in the rock, it would be more like that of a bluebottle path described by a particle, such as a sand grain in the rock, it would be more like that of a bluebottle buzzing round the room; it would be up and down, to and fro and from side to side.

More fantastic still is the information given in the ancient Chaldean work, The Sifrala, which contains over one hundred pages of technical details on building a flying machine.

更大的幻想仍然在古代的占星术作品中。《悉法拉》，包括了一百多页的飞行机器制造技术的详细资料。

In a warehouse in Davis, Calif., an inventor named Paul Moller is building the M-400 Skycar, which he says will be able to take off and land vertically, hover, and fly at up to 300 mph.

在加利福尼亚州戴维斯的一个仓库中，一位名叫保罗·莫勒的发明家正在制造型号为M-400的飞天汽车，他说这种车可以垂直起降，盘旋，并且以300英里以上每小时的速度飞行。

The German theosophist Rudolf Steiner writes lucidly in his otherwise kooky Nine Lectures on Bees:"Just as the human soul takes leave of the body...one can truly see in the flying swarm an image of the departing human soul."

德国神智学者鲁道夫斯坦纳（4）在其另类怪僻的《关于蜜蜂的九个讲座》中清楚地写道："正如人类灵魂脱离人体……通过飞行的蜂群，你可以真实地看到人类灵魂分离的影像。"

T. --titular hero of Steven Spielberg's movie--on a desperate mission to save his planet.

They are:1the realization of thermal-protection and seal at the same location,namely the seal performance in the high temperature environment during atmospherical re-entry;2the screen of TPS materials which have a synchronic-ablative characteristic between the glass and adjacent material of the window,to avoid the appearance of steps,and hence the over-heating caused by the disturbing of gas flow;3the analysis and calculation program for distribution of temperature in a complex structure consisting of a series of different materials including transparent materials;and 4the ground test program which can predict the performance of side-view window.

讨论了研制中国栽人飞船舷窗防热和密封结构的几个技术难题：1保证舷窗在返回的高温环境中防热与密封可靠；2保证窗玻璃材料与周围防热材料烧蚀同步，避免出现局部干扰热流；3进行多种异质材料，包括透明材料组成的复杂结构温度场的分析计算；4通过地面模拟试验准确地预测实际飞行条件下舷窗的防热与密封性能。

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。
