飞行器

A H_∞ filter is designed to estimate the navigation parameters for aerocraft vision navigation.

提出了用H∞滤波估计飞行器视觉导航参数。

In aerocraft structure system, there are lots of factors, such as the frame of the system, the use of composite materials and the running surroundings, which can lead the system presents severely nonlinear behaviours.

在飞行器结构系统中，由于结构本身特点、复合材料的使用以及运行环境的特点，使得系统呈现出强非线性特征。

Le Bris built a glider, inspired by the shape of the Albatross bird and named L'Albatros artificiel ("The artificial Albatross"). During 1856 he flew briefly on the beach of Sainte-Anne-la-Palud, by being pulled by a running horse, face to the wind.

受到信天翁形态的启发，勒布里制造了一架滑翔机，并将其命名为L'Albatros artificiel。1856年他主要在菲尼斯泰尔海岸飞行，依靠迎风奔驰的马作牵引，第一次说明了重于空气的飞行器是可以飞离地面的。

Ancient explore drawings of fantastic creatures, relic of construction strips in Peru, and Amerindic texts that exposit the "flying machines of the gods" were meet a whatever of the mismatched archeologic artefacts cited by von Daniken as grounds that ancient astronauts were substantially famous to our ancestors.

由Erich von Daniken撰写，1968年出版的畅销书《诸神的战车》提出了一个&远古外星人&的理论，颠覆了人们对于人类进程的信念。远古洞穴壁画中奇异的生物，秘鲁的飞机跑道遗迹，和印第安文字中所描述的&神的飞行器&这些反常的考古文物只是一小部分被von Daniken引用作为远古外星宇航员早已被我们的祖先所熟知的例证。

The name Aptera was chosen because the vehicle resembles a small, wingless aircraft.

之所以选用Aptera这个名字，是因为这种电动车像小型的无翼飞行器。

The main content of this article are the theories of fuzzy control system and data acquisition system for micro aerial vehicle . we can let a aeroplane model aviate with some sensors and one microcontroller , at the same time , the remote control is used .. when the model make a landing , we could get some useful data from the model

在信号采集系统的基础上，对微型飞行器模糊控制系统的具体实现进行了探讨，并分析了单片机与pc机串行通信的方法，进一步强调信号采集系统与模糊控制系统之间综合设计的合理性和必要性。

UK man Derek Burdon took photographs with his mobile phone in London and it captured 4 curious lights with strange shapes hovering over the Houses of Parliament, sparking a UFO debate, local media said Wednesday.

据英国媒体18日报道，英国男子德里克·伯登在伦敦科芬园的16层高楼处用手机拍照时，拍到了4个形状奇特的发亮飞行器，盘旋在国会大厦上空。

This paper introduces the way synchro equiped with differential transmitter take the place of traditional circumvolve coders and control the model gesture with two step electromotores.

1引言风洞是能人工产生和控制气流，用以模拟飞行器或物体周围气体的流动，并可量度气流对物体的作用以及观察物体现象的一种管道试验设备。

To conform to this system request and characteristic ,this system design uses the structurized method to design on the aircraft and the ground both sides communication protocol in- dependently.

为更符合该系统要求特点，采用结构化方法独立设计飞行器和地面双方的通信协议。

Has not gone home the joy, thinks plot then, they very wanted to advise against the heroic black German graceful senior officials actually, did not want to let him go, because escaped distressedly the crater "the star tyrant" a group, already was the dead end, had no need for he to make final preying on personally radically!

当星际飞行器，缓缓降落在地球总部基地的地面上时，回想着不久前，血雨腥风中战斗的一幕幕，大卫博士没有一丝回家的喜悦，想想当时的情节，其实他们很想劝阻住英勇的黑德曼长官，不想让他去，因为狼狈逃出环形山的&星霸&一伙，已经是穷途末路了，根本用不着他亲自去做最后的搏杀！

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。
