根据给定的目标建模算法和干扰反射杂波模型，模拟了不同信杂比下螺旋桨飞机和喷气式飞机的雷达回波，仿真结果表明，这两种目标具有不同的频谱结构，证明了给出的模型是有效的，为雷达系统提供了实用的回波仿真信号。

The return signal from propeller aircraft and jet plane in different SNR is simulated based on the statistic model of the disturbed clutter, and the calculated results are analyzed and compared. The results show that the model presented is valid and provides a useful simulated signal for the radar system.

根据给定的目标建模算法和干扰反射杂波模型，模拟了不同信杂比下螺旋桨飞机和喷气式飞机的雷达回波，仿真结果表明，这两种目标具有不同的频谱结构，证明了给出的模型是有效的，为雷达系统提供了实用的回波仿真信号。

This paper presents and theoretically analyses the design of a marine jet propeller riven byimpulsing current. This new Propeller has obviously a higher efficency in energy-saving and a higher speed than any other propellers available.

本文提出了船舶冲击电流喷射推进器的设想，并从理论上分析了这种设想在节能效果和提高船舶航速方面具有比螺旋桨推进器明显优越的特性。

Jet planes have displaced propeller ones.

喷气式飞机取代了螺旋桨飞机。

The C8 Aileron's design is heavily inspired by Spyker's aviation heritage, as was the case with all previous models, but with a clear emphasis on the jet engine and not the propeller that adorned so many elements of Spyker's earlier cars.

将其命名为C8副翼的设计灵感来自世重的航空遗产，这一点与以前的所有机型，但有明确的重点放在喷气发动机和螺旋桨的不是这么多的装饰元素爵早些时候汽车。

If you are a student of aviation history (or perhaps a really crusty old lieutenant colonel), you will recall a lot of nervous hand wringing in the late 1940s and early 1950s as jet-propelled aircraft began replacing the props.

如果你是一个研究飞行历史的学生（或者也可能是一个非常有性格的资深中校），你可能会回忆起关于上世纪四十年代末五十年代初喷气动力飞机开始取代螺旋桨飞机时许多由于紧张而湿透的手心。

Lifting eye plates are to be fitted on stern shell plating in way of rudder and propeller.

在尾部船壳上设置坚固的眼板，用于拆装螺旋桨和舵。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
