螺旋桨

Net tonnage is 2,200 tons. The twin screw propellers are inward. The revolutions at full speed are 106 r/min.

总吨12000吨，净吨2200吨，双螺旋桨推进时内旋，全速前进为106 r/min 。

With differential geometry knowledge, the local characters of the blade surface are analyzed. Based on researching the cylindrical cutters osculating location, the methods to calculate the osculating location of the conic cutter and the torus cutter are discussed. A method of tool path planning based on the second order osculating method is preferred.

利用微分几何学知识，分析了螺旋桨桨叶曲面的局部特征，在研究圆柱刀二阶密切法规划刀位的基础上，探讨了圆锥刀和圆环刀的二阶密切刀位计算方法，采用二阶密切法规划刀位可以显著地提高加工精度。

If the special characteristics of an outboard motor fitted to a rescue boat would not allow it to be run other than with it's propeller submerged for a period of 3 min, it should be run for such period as prescribed in the manufacturer's handbook.

如果装在救助艇上的舷外发动机由于其特殊性在螺旋桨没有浸没的情况下不允许运转3min，则其运转应按制造商的手册规定的时间进行。

Like the somewhat similar Hiller VZ-1 "Pawnee", the Aerocycle carried its single pilot and 32kW engine on a circular platform located just above two belt-driven, contra-rotating fifteen-foot propellers.

像有些类似希莱尔弗策- 1"波尼"的Aerocycle进行旋转15英尺的驱动螺旋桨，禁忌单的试点和32kW的发动机在一个圆形的平台上方还有两个带。

New items have been added, including a Propeller Suit which allows players to fly and a Penguin Suit which allows players to freeze enemies.

同时，新增的道具有：螺旋桨衣服可以让玩家飞起来，而企鹅服可以让玩家冻住敌人。

On the other hand, the proportions of the propeller looked a bit wrong.

在另一方面，所占的比例螺旋桨的期待有点错误的。

First is matching the propeller to the engine.

首先是匹配的螺旋桨发动机。

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。
