涡轮发动机

But not all the air passing through an engine needs to go through the turbine.

但是并非所有通过发动机的空气需要经过涡轮。

The application of the gas turbine to jet propulsion has avoided the inherent weakness of the rocket and the athodyd, for by the introduction of aturbine-driven compressor a means of producing thrust at low speeds is provided.

应用燃气轮机于喷气推进避免了火箭和冲压喷气发动机固有的弱点，因为通过采用涡轮驱动的压气机提供了低速时产生推力的一种手段。

In fact, the jet propulsion engine, whether rocket, athodyd, or turbo-jet, is a piece of apparatus designed to accelerate a stream of air or gas and to expel it at high velocity.

实际上，喷气推进发动机，无论火箭、冲压喷气、或者涡轮喷气，都是设计成加速空气流或者然气流并将其高速排出的一种装置。当然，如第2章中描述的那样，这样做有不同的方式。

Although the V6 models will do battle with low-end Mustangs and Challengers, a turbocharged four-cylinder is still not out of the question.

虽然V6发动机车型将尽战斗低端野马和挑战者，涡轮增压4缸发动机仍然没有摆脱这个问题。

Turboprop engines have more in common with jet engines than they do with piston driven units.

涡轮螺旋桨发动机有更多的共同点与喷气发动机比他们做的与活塞驱动的单位。

The latest "high bypass" turbofans, such as the Rolls-Royce Trent, push around nine times more air around the core of the engine than through it.

最近的高涵道比涡轮风扇，例如罗罗的遄达发动机，推动空气通过发动机核心周围的空气相较于通过核心气量9倍。

When combined with a turbocharger (a supercharger driven by exhaust gases), Fiat engineers talk of producing a "downsized" two-cylinder engine that performs like a bigger four-cylinder one, but with fuel savings of some 20%.

和涡轮系统协同工作，按菲亚特工程师的说法，一个小尺寸的两缸发动机可以提供和大一号四缸发动机同样的性能，而且节油大约20%。

This revamp also saw the introduction of two new engines, a 2.0 version of the existing V6 engine (which retained the carburettors) and a 2.5 litre VM 5 cylinder turbodiesel.

这种改革还看到了两个新的发动机，现行的V6发动机的2.0版本的推出和2.5升5缸涡轮增压柴油船民。

The new car will debut a host of super-efficient turbocharged petrol and diesel powerplants, and is set to be fit ted with a start-stop system that sw itches off the engine in stationary traffic to save fuel and cut em is sions.

新车将推出一系列超高效涡轮增压汽油和柴油发动机，并设置为配备起止系统的开关关闭发动机固定流量，节省燃料和减少排放量。

For the DRDO even a successful Kaveri flight will be a bittersweet end to one of India's most savagely criticised development programmes.

对于&印度国防研究和发展组织&（&印度涡轮燃气研究院&是其下属的一个研究院）而言，作为印度最饱受指责的项目之一，&卡佛力发动机&的飞行即使成功也只是个苦乐参半的结果，一方面，它是一个成功的标志，意味着完成了制造现代发动机的雄心勃勃的技术飞跃，而目前仅有少数几个国家掌握该技术。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
