Compared with dissymmetrical engines, the results show that the contrapositive cam engine can balance the axial force with larger torque output and lower loads on shafting bearings.

研究结果表明，虽然对置后发动机轴向长度有所增加，但主轴轴向力能完全平衡，主轴产生转矩大，轴承负荷小，可提高功率。

And that's the engine's control panel.

这就是发动机的控制面板。

Their power was also increased by introducing a control rod which moved up and down with the beam.

因为增加了一根随着吊杆上下移动的控制杆，发动机的功率也增大了。

Moreover, it analyses the time sequence of control to different work phases and control law of nozzle.

本文的研究工作对航空发动机数控系统的设计改进具有一定的参考价值。

Based on the above experimental research, suggestions have been made to improve engine structure and control system.

基于以上实验研究，提出一些改进发动机结构和技术发展方向的建议。

However real-world issues reduce the efficiency of actual engines, due to limits of convective heat transfer, and viscous flow.

然而现实世界的问题，降低效率，实际的发动机，由于界限的对流换热和粘性流动。

It is equally important never to use water alone as an engine coolant.

同样重要的是，不要单发动机冷却用水。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
