THE connection between an 18th-century savant called Joseph-Louis Lagrange and the problem of landing safely at Hong Kong International Airport may not, at first, be obvious. But there is one. Hong Kong airport is notorious for rocky and sometimes aborted landings caused by the disturbed air flow from nearby mountains. Though laser technology is deployed alongside its runways to monitor changes in wind speed and thus forewarn pilots, that is often not enough. What is needed is a better understanding of the theory of the winds themselves.

十八世纪的学者Joseph-Louis Lagrange同香港国际机场飞机的安全降落之间乍观起来并没有明显的联系，但是，实际上是有的，香港机场以其路面坚硬、附近山上吹来的空气涡流常常飞机降落的被迫取消而臭名昭著，尽管沿着飞行跑道部署了最新的科技手段以监视空气风速的变化，从而给飞行员以提前警告，但这常常是不够的，需要的是对风本身理论上的更好的理解

The bow-wave, the region of disturbed air around aircraft engines, could damage a tailplane if the engines were located near it,so tailplanes of rear-engined aircraft are mounted above the jets, often above the fins.

如果平尾装在接近弓形波，也就是飞机发动机周围产生干扰气流的区域，弓形波就会破坏平尾，因此发动机装在机身后部的飞机的平尾被安置在喷气机的上面，通常是在垂尾的上面。

But a group of researchers at Stanford University, led by Ilan Kroo, has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use, and it would not require them to buy new aircraft.

克鲁领导的一个研究小组提出，飞机的飞行路线可以改用更具仿生效应的路径来节省燃油，而且并不需要购买新的飞机。克鲁教授称这个设想是受到鸟类的启发。1914

The paper chooses the assembly of aircraft digital assembly location as a research object, chooses the assembly of aircraft section as a research example, aims to study the method of aircraft digital assembly location, focuses on the research of the structure of digital assemble control prototype system for aircraft section based on laser measurement, develops the servo control device and related software based on LM629, ATmega128 and LMD18200, completes the construction of the system based on the assembly of aircraft section.

以飞机的数字化装配定位为研究对象，以飞机舱段的装配为例，以探索飞机数字化装配的方法为目的，通过对基于激光测量的飞机舱段数字化装配定位控制原型系统结构的研究，采用运动控制芯片LM629、单片机ATmega128和功率放大芯片LMD18200构成了伺服系统控制随动装置，并开发了相关软件系统，完成了基于舱段大部件装配的数字化装配定位控制原型系统的设计开发。

It is painting the exterior of its planes with lighter paint, creating lighter fittings onboard, changing oxygen bottles from metal to carbon fibre, and it is now using cargo bins made from lighter but stronger carbon-fibre materials, rather than metal.

他们用浅色的颜料涂染飞机的外壳，还在机舱内部配置了较轻机载设备，并将铁质的氧气瓶更换为碳纤维质地。现在，维珍航空还将飞机后备箱的材料用更轻更坚实的碳纤维替代了以前的金属。

Flying over areas that had already been mapped by conventional geologic techniques, l'avion renifluer , or "the sniffer plane" was spectacularly successful in picking out oil fields

这个叫做嗅探飞机的装置已经使用於传统地质学绘制地图的技术，还曾经成功地探测出油田这个叫做嗅探飞机的装置，在飞过曾以传统地质技术探勘过的区域时，非常成功的找出油田位置

根据给定的目标建模算法和干扰反射杂波模型，模拟了不同信杂比下螺旋桨飞机和喷气式飞机的雷达回波，仿真结果表明，这两种目标具有不同的频谱结构，证明了给出的模型是有效的，为雷达系统提供了实用的回波仿真信号。

The return signal from propeller aircraft and jet plane in different SNR is simulated based on the statistic model of the disturbed clutter, and the calculated results are analyzed and compared. The results show that the model presented is valid and provides a useful simulated signal for the radar system.
