翼型

Then the lift and torque models of double wings fin stabilizers flapped lengthways and single wing fin stabilizers flapped breadthwise at zero speed are acquired on the basis of step by step degenerate derivation.

根据Weis-Fogh机构的组成和结构特点，论文提出了双翼纵向拍动型、单翼纵向拍动型和单翼横向拍动型三种类型的零航速减摇鳍。

Methods: 45 cases with sphenoidal ridge meningioma operated were retrospectively analyzed. Acording to the site,all the 45 cases were divided into 2 groups ,outer(32/45) and inner(13/45) sphenoidal ridge meningioma . All the cases were operated with microscope.

回顾分析一组45例蝶骨嵴脑膜瘤手术治疗的资料，所有病例根据其生长部位，分为内侧型和外侧型两种，其中外侧型32例，内侧型13例，均采用翼点入路或改良翼点入路，显微镜直视下行手术切除。

The tip speed structural limit is based on the centrifugal pull that can be carried at the base of the blade airfoil for the selected material and is generally expressed as allowable annulus area x N2 versus temperature.

尖端的速度结构的限制是基于离心拉，可以进行在该基地的叶片翼型为选定的材料，并普遍表示允许环区x氮气随温度的。

Assembly consists of thumb screw, hooks, swivel joint, and stem, threaded at one end.

这种总成由翼型螺丝、钩、转接头和杆子组成，在一端上有螺纹。

Use a sanding block to sand out the airfoil.

使用砂块砂出翼型。

First of all, draw the airfoil on both ends of the balsa wood which can guide you through the sanding process.

首先，提请翼型对两端的balsa木材可以指导您通过砂的过程。

The other drag contributions are airfoil shape, wind induced drag, tail drag, fuselage and landing gear drag, interference drag, cooling drag and a few more.

其他拖曳的贡献是翼型的形状，风致阻力，尾巴拖曳，机身和起落架阻力，干扰阻力，冷却拖曳数更多。

But, for all this to be effective, the tail must be set so that in cruise the drag is minimized by having the elevator in line with the stabilator, and the whole tail airfoil at an incidence compatible with the general airflow at this location within the downwash of the wing.

但是，这一切是有效的，尾巴必须设置，以便在巡航阻力减至最低，由电梯在符合塔比利特，和整个尾巴的翼型在一发病兼容与一般的气流在这个位置内部向下的机翼。

The clear NACA 0012 was used airfoil as a standard model to validate the numerical model that will be used in the following simulation.

工作中首先以未结冰的NACA 0012翼型为标准模型进行了数值验证计算，再以经过检验的方法计算结冰模型，并与结冰风洞试验数据进行了对比。

First of all lets kill some preconceived ideas on the aerodynamic effect of the brake controls by remembering the basic rules acting on airfoils, which have been experimentally determined by great people like Otto Lilienthal and theoretically proven by mathematicians such as Joukowsky.

首先我们需要抛弃我们自己所有的先前对于刹车的气动力作用的理解，仅仅记住作用于翼型上的最基本的原理――这些由伟大的先驱们如 Otto Lilienthal （奥托·李林塔尔(1848-1896)用试验证明，理论上由Joukowsky 使用数学方法所验证的理论。

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。
