During one of these turns the Flanker, rather than continuing to the expected heading, stopped at the Eagles dead six for 3000 feet.

这就是整个所谓对抗的全过程，大家编队飞行，SU忽然没按规定动作跟着F-15而是忽然咬住屁股，美国飞行员奇怪那家伙在做什么并且尝试摆脱，但20秒内摆脱不了，就这样。

He said:'Seeing starlings fly in these incredible formations truly is an amazing sight.'The birds flying together like a school of fish, all their movements in sync.

他说：看到欧掠鸟难以置信的编队飞行，的确太神奇了，这些飞翔的鸟像一群鱼一样同步运动。

Numerical results show that this method is suitable for the preliminary design of formation flying.

仿真结果表明，此方法适用于编队飞行的初步设计。

In this dissertation the relative motion with perturbation motion of spacecraft is studied systematically, and t...

论文对航天器相对运动及摄动进行了较为详细的分析，同时研究了多个航天器编队飞行的可能构型方式和控制方法。

One of the difficulties of satellite formation flying is to control the formation in perturbation environment.

卫星编队飞行的难点之一是在干扰力环境下控制队形。

This is a satellite formation flying of the relevant procedures, the relative orbital motion control simulation.

详细说明：这是一个卫星编队飞行的相关的程序，对相对轨道运动进行控制仿真。

This paper focuses on the geometrical properties of Inter-Satellite Links of the small satellites formation flying under the elliptical orbits, including the azimuth, elevation and the distance.

摘要该文对编队飞行小卫星的星间链路几何特性(方位角、仰角及星间距离)进行较为深入的研究。

Flying a formation of satellites offers improved flexibility and redundancy and the ability to construct much large virtual sensors than can be flown on a single monolithic satellite.In this background, the thesis concentrates on the study of the formation design and station keeping, one of the critical technologies of formation flying.

卫星编队飞行技术可以使用若干个小卫星代替传统单个复杂的大卫星，并且具有提高系统灵活性，增加任务冗余度，超越传统单个大卫星功能的特点，因此在近几年受到国内外航天界的广泛重视，成为研究热点。

Two clusters of formation flying satellites with a relative angle on geosynchronous earth orbit were used to construct a space-based continuous navigation system for deep space exploration.

应用地球静止轨道的两个编队飞行卫星群构成天基的深空探测导航系统，可以全天候连续为深空探测器导航。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
