The results show that propellers operating in front of the liquid-cooled engine nacelle had higher take-off efficiencies than when operating in front of the radial engine nacelle; the peak efficiency was higher only when spinners were employed.

结果表明，在前面的推进器发动机实现了液体冷却效率更高的起飞了在前面比运行时的光线的引擎实现最高效率较高；只有当纺纱被聘用。

Methods:Refering to Sawyer"s "The rabbit diencephalon in stereotaxic coordix nates,putting grass microelectrodes into P2-5,L3-6,H6-9 of the HPC in 2 μm/s by SN-2 to induce discharge of neurons.

本实验采用侧脑室给药法，参照Sawyer兔脑图谱，用SN-2型推进器以2 μm/s速度将玻璃微电极插入海马P2-5，L3-6，H6-9处引导神经元自发放电。

The thrust is the result of a relativistic effect and would not occur under simple Newtonian physics.

他的理论以爱因斯坦的理论为前提，推进器原理也是相对论效应的结果，在经典牛顿物理学范围不适用。

In China, Rolls-Royce has a strong presence in the marine sector, having delivered a wide range of products, including deck machinery, tunnel thrusters, rudders, controllable pitch propellers, Azimuthing thrusters, waterjets and stabilizing systems over a number of years as well as a very comprehensive orderbook, covering a multitude of products and systems extending many years forward in time.
