翼的

The form of the delta wing has changed, the air intake is different, the shape of the nose section is different, the different shape and position of the canards, etc.

三角翼的形状改变了，进气道不一样，机鼻部分的造型不同，鸭翼的外形和位置不一样，等等。

We only hear that creature with wings can fly but never hear that creature like man without wings can fly. We know that people with experience and learning can read some books and make some comments but we don't know many 'ways of nescience' can do those without experience and learning.

我们只听说有翼的生物会飞，可是没听过没有翼如人的生物会飞；我们知道有经验，有学历的人会做些事，读些书，发表些意见言论，可是我们不知道有许多"无学之术"是不需要经验学习就会做的。

It is shown that the direction stability of the model fitted with wings with winglet s is better,and suitable winglet s can achieve the model s flight distance.

提出了3种不同的微型飞行器气动布局方案：平直机翼、"M"形机翼和附加翼稍小翼的气动布局形式。

Being given,an exact solution of the spatial distribution of interstellar gas is obtained,and the peak distribution of gas in disk-shaped galaxies is discussed.

分析了星系翼的一般特征，并具体地计算了银河系中星际气体的等密度曲线，提出了银河翼结构的一些可能趋势。

Modern fighter aircraft feature various combinations of canards, tailplanes and compound wings.

现代战斗机采用的是各种鸭翼、尾翼和复合翼的组合。

Rotor to be stable: If, for some reasons, the load on the rotor increases, the torque tube is tilted forward and

这样的连接方式帮助旋翼保持稳定：假设因为某些原因，旋翼上的载荷增加了，扭矩管会随之向前倾斜，这时候旋翼的攻角降低

The effect of Gurney flap on double delta wing aerodynamics was conducted in low speed wind tunnel,the experimental results indicated that Gurney flap can promote the model s lift coefficient,maximum lift coefficient and lift-to-drag ratio at middle to high lift coefficient.

通过低速风洞实验研究了Gurney襟翼对双三角翼气动特性的影响，结果表明Gurney襟翼可以提高双三角翼的升力系数、最大升力系数以及中高升力系数情况下的升阻比。

Another good point of the tandem rotors is that no tail rotor is needed to counter the torque so that the power efficiency is excellent.

纵列双旋翼的另外一个好处是不象其他直升机那样需要一个尾桨来平衡旋翼的扭矩，动力效率高。

It's better to avoid the stalls, spins and collapses in the first place by flying a heavier-loaded wing.

计算结果给出不同展弦比和带端板地效翼的气动特性曲线，揭示展弦比和端板对翼尖涡涡核位置和下洗角的影响规律。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
