在高空的

The analysis result proves that the design for improvement is more suitable for the design of longitudinal control laws for HALE tailless flying-wing UAV because the autopilot of flight control system is always in-the-loop, it is not necessary to consider the stability augmentation performance of control system such as traditional method.

分析结果表明，由于无人机飞控系统的自动驾驶仪是始终在环的，不必像传统方法一样考虑带有增稳的控制系统的稳定性。因此，改进的设计方法更适合于无尾飞翼式高空长航时无人机巡航状态的纵向飞行控制系统的设计。

Imagine, if you will, that each of these two professors of English Literature (both, as it happens, aged forty) is connected to his native land, place of employment and domestic hearth by an infinitely elastic umbilical cord of emotions, attitudes and values a cord which stretches and stretches almost to the point of invisibility, but never quite to breaking-point, as he hurtles through the air at 600 miles per hour.

不妨发挥一下你的想像力，假设这两位文学教授(都正好40岁)与各自的故土--他们工作的地方，他们家中的壁炉边--之间，都有一条弹性无穷大的纽带将他们相连，这条纽带交织着他们的情感、态度和价值观--他们各自以每小时600英里的速度在高空飞行时，这条纽带被拉伸到几乎看不见但又不至崩断的地步。

Many of the world's most accomplished trapeze artists, high-wire acts and aerialists are showcased at the Circus Circus Midway Stage, which presents complimentary performances every hour from 12 p.m.

许多世界上最高超的高空秋千艺人、高空钢丝表演者和高空杂技师都在马戏团酒店中途岛大舞台进行表演，从中午 12：00 开始，每个小时都会有免费的表演。

And after a long time the rough rocks were decked out with soft mosses and trailing vines, and all the nooks were hung with clematis and columbine, and great elms lifted their huge tops high up into the sunlight, and down about their feet clustered the low cedars and balsams, and everywhere the violets and wind-flower and maiden-hair grew and bloomed, till the canyon became the Master's favorite place for rest and peace and joy.

过了很长一段的时间之后，粗糙的岩石上，铺满了柔软的青苔和绵延的藤蔓，各处角落，都垂挂着铁线莲和缕斗菜，硕壮的榆树，仰起粗大枝干，升向高空的阳光，树根附近盘屈着矮杉和凤仙花，到处都有紫罗兰，白头翁和孔雀草在生长开花，峡谷终于成了主人所寻求的安息，平安和快乐的心爱之地了。

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。

The changes of monthly mean wind speed and monthly mean temperature with time have different laws between desert hinterlands and its fringe.

初步得到了以下一些结论：(1)塔里木盆地的环流形势是在高空西风带的背景下，经过青藏高原、天山山脉的动力分支和抬升，以及沙漠本身的热力作用下共同形成的。

A solid, geometric base knits it tightly into the urban fabric of the city block, while a smoother shaft takes it up into orbit and a crown begins to dematerialise and reduce its volume as it hits the sky.

它的三重组成部分与传统装饰性摩天大楼的设计相呼应。坚实的几何地基与街区的城市构造紧密交织，平滑的中轴将大楼带入轨道，楼冠逐渐变得非现实性，并在高空中削减了建筑的体积感。

Before the actual flight tests, Russian experts at Moscow's Central Institute of Aviation Motors will run ground checks on the Kaveri's performance, in conditions that simulate altitudes up to 15 kilometers (49,200 feet).

在实际飞行之前，莫斯科中央航空动力研究所的俄国砖家将对&卡佛力发动机&进行15000米高空的模拟环境下的地面测试。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
