下飞机

As many as 20 firefighters can rappel to a fire from a turbo-powered Mi-8 helicopter, but haven't forgotten their roots. They also parachute from decades-old biplanes, much as they did when they pioneered smoke-jumping in the 1930s.

虽然一架涡轮透平动力的米-8直升飞机最多可载20名消防员去执行灭火任务，但是俄罗斯的空中护林员们从未忘记它们的本职工作，他们仍然会像上世纪30年代时他们的先驱者那样从已经几十岁的双翼飞机中利用降落伞跳下。

"You can see airplane contrails, and occasionally at the end of an airplane contrail, you will see a glint of sunlight off the airplane," Lu says. And very occasionally, you do see other satellites go by.

&你可以看到飞机尾迹，偶尔在尾迹的一端你可以看到闪亮的飞机&LU说，更偶然的情况下，你可以看到飞经的其他人造卫星。

Each plane carried a 500-pound bomb, napalm, and newly installed five-inch rockets on tracks under the wings, four rockets on each wing, plus the .50-caliber machine guns on each wing.

每架飞机携带一枚500磅炸弹，一枚凝固汽油弹，两机翼下两挺点50机枪，并挂着新配装的4发5英寸火箭。

Under the constant scenario, an American who forgoes having a child would save 9,441 tonnes of CO2 almost six times, on average, the amount of CO2 they would emit in their own lifetime, or the equivalent of making around 2,550 return airplane trips between London and New York.

在保持不变的情境下，一个放弃生孩子的美国人可以减排9441吨二氧化碳，几乎是其毕生排放总额的六倍，相当于坐飞机在纽约和伦敦之间往返2550次。

Instead of draining rivers, society directs a human stream into a bed of trenches; instead of dropping seeds from airplanes, it drops incendiary bombs over cities; and through gas warfare the aura is abolished in a new way.

社会不去排干河流，反倒把一只人的洪流引入战壕；它不用飞机播种，而是用它在城市的上空投下炸弹；毒气战争更以一种新的方式消灭了灵晕。

Liberia's besieged leader Charles Taylor flew into exile in Nigeria as hundreds of Liberians, thin and ragged, prayed his departure would mark a turning point for their war-torn country." turning point "的意思是转折点(a point in time at which a very important change takes place).

An axisymmetric,three-dimensional engineering model of microburst was used in the simulation of aircraft take-off with windshear encounter.

采用较真实的三维微下击暴流工程化模型和非线性动态逆方法，对飞机在起飞过程中的纵向/横侧改出低空风切变的控制律进行了设计和仿真。

Benefits of this system were obvious over a conventional twin layout, with only the same frontal area as a single-engined aircraft, the wing left clean of engine nacelles and attendant structures, and no asymmetric pull if one engine cut out.

这样的系统的好处明显超过了传统的双螺旋桨布局形式，他就如同一架具有有相同迎风面积的单引擎飞机。不在机翼下安置发动机舱和辅助结构，就不会因为一台发动机的熄火而产生不对称的推力。
