The nineteenth century witnessed a revolution in ship design and propulsion.───19世纪经历了船舶设计和推进上的一次重大变革。
Propulsion is provided by a rocket engine, rather than a propeller and rudder, which makes steering difficult.───推进器是由火箭发动机提供的，而不是螺旋桨和方向舵，这使得转向变得困难。
Scientists and engineers are beginning to study this ability of fishes in the hope of designing more efficient propulsion systems for ships.───科学家和工程师们开始研究鱼类的这种能力，希望能设计出更有效的船舶推进系统。
This requires guiding into and along the surface (pipe) floats, as well as propulsion and a parking brake.───这要求导入和沿着表面（管）漂浮，既需要推力也需要停止闸。
This model, however, remains tethered to the ground at all times, as it has not been equipped with a propulsion system.───然而这个飞行器一直拴在地面，因为还没有装备推进系统。
Since such a lowly satellite would suffer from atmospheric drag, it would need its own propulsion system and a decent supply of fuel.───如此低空飞行的卫星会受到大气层的拖赘，本身需要推进系统和足够的燃料。
Moreover, these networks have also been used in a neuromechanical model simulating actual locomotion with propulsion and steering.───此外，这些网络模拟还被用于一个神经机械学模型来模拟包含有推进和方向控制部分的真实运动。
The test platform will be an important platform used to studying the mechanism and control of the long flexible fin undulatory propulsion.───论文研究的测试平台将为柔性长鳍波动推进机理及控制技术研究提供重要试验平台。
"Propulsion, " the nine-year-old says as he leads his dad through the gates of the U. S. Space and Rocket Center in Huntsville, Alabama.───“推进，”九岁的小男孩一边说，一边带着父亲穿过阿拉巴马亨茨维尔太空火箭中心的大门。
