查询词典 propeller

The probable cause of the accident was determined to be the failure of the propeller due to undiscovered

有充分证据显示这起意外的发生原因是腐蚀造成的

However, at the touch of a button, telescopic wings emerge from the roof; a rear propeller pops up from the trunk; the "spoiler" becomes a vertical stabilizer that extends up over the car; and, finally, a pair of horizontal stabilizers appear from just behind the rear wheels.

不过，只需轻摁按钮即可弹出伸缩机翼；后面的螺旋桨从车厢来出现；&扰流器&变成垂直稳定翼，延伸至整个汽车；最终，两个水平稳定翼会从后轮后面现身。

A maneuvering mathematical model for Controllable-Pitch Propeller ships with three degrees of freedom is established according to separate modeling theory. Based on Netherlands Ship Model Basin\'s open-water tests, CPP thrust coefficients and torque coefficients in four-quadrant with different pitch ratio of screw and different types of CPP are obtained by using Akima interpolation. Therefore, CPP thrusts and torques are obtained.

基于船舶操纵性分离建模理论，采用荷兰船模试验水池B系列螺旋桨的敞水试验结果，利用Akima插值获得了不同类型的调距桨在不同螺距比下的四象限推力系数和扭矩系数，求得调距桨的推力和扭矩，建立了调距桨船舶的平面运动数学模型。

A mathematical model of computing ship motion in crash stopping is proposed and a new method for dealing with hydrodynamic forces and moments of propeller based on the principle of ship propulsion and manoeuvrability is put forward in this paper.

基於船舶推进和船舶操纵性理论，建议了一个计算紧急停船运动的数学模型，并对其中的螺旋桨水动力和力矩提出了一种新的处理方法。

If the plane is designed to fly slowly, use a long, low pitch propeller to see the best possible performance.

如果该飞机的设计飞行缓慢，长期使用，低螺距螺旋桨看到最好的性能。

The relational expression of the speed difference of drum and spiral propeller (Δω0) and the difference of drum speed and input speed of the differential gear (Δω1) is derived.

由于钻井液的比重和粘度是随井下情况变化的不确定值，且现场对钻井液的处理量时有变化，需随时调节Δω0或Δω1以调节离心机的处理能力和效果。

The Derwent and Nene turbo-jet engines had world-wide military applications; the Dart turbo-propeller engine became world famous asthe power plant for the Vickers Viscount aircraft.

德温特&和&尼恩&涡轮喷气发动机获得了世界性军事应用；&达特&涡轮螺桨发动机作为维克斯公司&子爵飞机的动力装置而闻名于世。

I was just taking her hand, to help her out of a car, and I knew it.

我只是握着她的手，扶她下车，但我知道这一切。

China and South Korea have excoriated Japan over its approval of new school books which they say whitewash the atrocities committed during Japanese occupation, and anti-Japanese protests have been held in Chinese cities. The lingering bitterness over Japan's past imperialism still threatens to mar relations between the big East Asian powers

中国和韩国强烈谴责日本通过新的中学历史教科书，他们认为这一教科书掩盖了日本在其占领期间所犯下的残酷暴行，反日抗议活动在中国数座城市发生，历史上日本帝国主义制造的痛楚无法被忘却，这有可能破坏东亚强国间的关系。
