The Airport Security in the work of the Airport so that he is the head of the bird pest problems because of Zhangjiajie Airport is located in the mountains, birds at the airport, air space flight in particular, the safety of aircraft flying will be very much affected, and the bird work for the Airport Security Field Services team that is a major problem, how can we solve this problem to ensure flight safety?

而机场保障部工作中最让他头痛就是机场的鸟害问题，由于张家界机场位于山区，鸟类在机场空域飞行特别多，对飞机的安全飞行是有很大影响的，而驱鸟工作对于机场保障部场务队来说就是一大难题，如何才能解决这个难题保证飞行安全呢？

With the rapid developments of science and technology, the modern avion simulation system faces two requirements. One is function requirement and the other is technology renovation requirement. As to the first requirement, functions of modern avion are becoming more and more abundant, which causes the flight simulation training change greatly. As to the second requirement, with the development and adoption of new technology, high verisimilitude requirements are raised to avion simulation system.

中文题名现代军机飞行仿真系统的研究副题名外文题名 A study on modern avion flight simulation system 论文作者黄安祥导师李明陈宗基学科专业导航、制导与控制研究领域\研究方向学位级别博士学位授予单位北京航空航天大学学位授予日期2003 论文页码总数150页关键词军用飞机飞行仿真系统仿真馆藏号BSLW /2003 /V271 /3 随着科学技木的飞速发展，现代军机仿真训练系统面临两大需求：一是功能需求，现代军机功能的增强，使飞行仿真训练内容发生了较大变化；二是技术更新需求，新技术的发展及其在仿真系统中的应用，对军机仿真系统的逼真度提出了更高的要求。

The effect of empennage spread on flight attitude was analyzed and validated by flight test data.

针对某型导弹尾翼展开过程对飞行姿态的影响进行了细致地分析，并通过飞行试验数据对分析方法加以验证；最后论证了尾翼展开的不同步性会影响导弹的飞行姿态。

Technologies such as DirectX, object oriented programming and database are used to realize visual three-dimensional flight simulation system. In the simulation system, operator controls UAV with flight rod. The system can display the change of position and track for UAV with the change of operational input. Flight simulation data can be also recorded. Then we can analysis the operation and stable performance of UAV without empennage with qualitative and quantitative methods.

运用 DirectX、面向对象编程与数据库等技术，实现了基于 PC 机的三维虚拟飞行仿真系统，通过人机交互飞行，可以比较直观地显示无人机的姿态与轨迹随操纵输入变化而变化，同时也可记录分析仿真飞行数据，从而对无尾式无人机的稳定性与操纵性能进行定性与定量的分析评估。

Hegira or Hejira (Arabic hijrah,"flight"), specifically, flight in AD622 of Muhammad from Mecca to Yathrib, both in what is now Saudi Arabia; by extension, the term is applied to any similar flight or emigration.

hegira或hejira （阿拉伯语hijrah ，&飞行&），具体来说，在飞行ad622的穆罕默德从麦加到yathrib ，无论是在现在的沙乌地阿拉伯，通过扩建，该术语适用於任何类似的飞行或移民。

Using entomological radar, we showed that the ability to select seasonally favorable, high-altitude winds is widespread in large day- and night-flying migrants and that insects adopt optimal flight headings that partially correct for crosswind drift, thus maximizing distances traveled.

根据所搜集到的雷达对天空中迁徙飞行的昆虫进行扫描的数据，Jason Chapman 及其同僚显示，在高空飞行的蛾子和蝴蝶能够选择有利的风向并纠正其方向的偏移，这些策略可使昆虫所覆盖的地面最大化，并使它们的飞行时间得到最佳化。
