牵引

It computes wind factors for flight data file, uses differential equations to solve for position and tension vectors as a function of arc length, and uses Runge-Kutta method for integration of ordinary differential equations.

该软件计算用于飞行数据文件的风向因素，使用不同的方程式，比如一个弧线长度函数来解决位置和牵引方向问题，使用 Runge-Kutta 方法解决综合推理差异方程式。

Through the calculation on flexivity of drag-chain and length of chain curve,set screw-pull-ing instrumentneeds to be adaptedto suitable period.

通过对牵引链的挠度和链曲线长的计算，确定链传动需要调整的适当时期。

Early release of the levator fascia during open RP results in better potency according to his data at this meeting.

根据他在会议上提供的数据，开放性RP中及早解除提肌筋膜的牵引将有助于勃起功能的改善。

And you lift me up in a wave of love...

在爱的浪潮中，你牵引著我

The effects of radii of curvature of ellipsoids, surface entraining velocity, normal load at the contact point and the limiting shear stress on the distribution of pressure, profile and thickness of oil film, three dimensional shear stress and traction coefficient have been studied.

三、分析比较了弹流润滑过程中润滑油和牵引油的各种流变模型，首次采用了四次方型粘塑性流变模型来描述润滑油在弹流润滑过程中的流变特性。

Do not wrap Tag Line around your hands or body.

不要把牵引线缠在手上或身上。

In the study, the authors considered the formation mechanism of the "y"- type structure as follows : the EW - trending compression stress field was derived from the sinistral strike - slip of Wufengxian - Tiesitang fault in Indosinian orogeny and the traction of the sinistral strike - slip made the NNE -trending structural lineament produce sinistral torsion in the west part of the Anren county seat, thus the NNW - trending folds were resulted.

研究认为，"y"字型构造形成机制为：五峰仙-铁丝塘断裂在印支运动中具基底左旋走滑性质，走滑所派生的近东西向挤压应力场，及走滑所产生的牵引作用，使安仁以西NNE向构造线产生逆时针旋转，从而形成NNW向褶皱。

In this case, we tried to use the alveolar bone splitting technique with the Piezosurgery, and the incison line was put in the alveolar ridge as lingually as possible that the integrity of the cortical plate of the alveolar ridge is reserved in the buccal side. Because the resistance to the mesial movement of the posterior teeth is greatly decreased, the possibility of the root resorption or dehiscence is reduced, and the stability after the orthodontic treatment would be improved while the height and width of the alveolar bone increase.

本病例尝试以超音波骨刀，於缺牙区进行齿槽骨劈开手术，其切线尽可能靠近齿槽之舌侧，以使齿槽上的皮质骨板可完整置於颊侧；这样当后牙向前牵引时，才不会因皮质骨板而阻碍前进及牙根被吸收或裂开，同时也能增加齿槽骨之高度与宽度，亦可使矫正后的牙齿更加稳定。

EMD is the global leader of railroad domain all the time, outstanding performance makes EMD engine can answer any environments leisurely, from beauty of north and south the mainland goes to thing Europe each country, arrive from Australia llano the Sahara, arrive from Siberia the Andes, arrive from bright phearl Hong Kong treasure island Taiwan, all howl of heavy-load train of EMD engine tractive has sailed.

EMD一直是铁路领域的全球领导者，卓越的性能使EMD机车能够从容应对任何环境，从南北美大陆到东西欧各国，从澳洲大草原到撒哈拉沙漠，从西伯利亚到安第斯山，从明珠香港到宝岛台湾，均有EMD机车牵引的重载列车呼啸驶过。

In new condition they excel on low traction surfaces as well as high "loamy" traction wet surfaces where no rubber has been taken into the racing surface.

在新的条件下，他们擅长的低牵引力表面以及高"壤土"牵引湿面如果没有橡胶已经考虑到赛车表面。

Do you know, i need you to come back

你知道吗，我需要你回来
