诱导阻力

Induced drag occurs at low speeds and at higher speeds as, at wing tips, air moves from the area of high pressure to the area of low pressure.

诱导阻力发生在低速和在更高的速度，在机翼的秘诀，空中动作，从该地区的高压力，向低压区的压力。

This configuration can theoretically provides 50% reduction of induced drag through varying the lift distribution between the two wings.

在理论上通过改变2个机翼之间的升力分布可以使得飞机的诱导阻力有较大减少。

At an altitude of 1/10 wingspan, however, induced drag is decreased by half.

在翼展十分之一高度的时候，诱导阻力减少了一半。

By using the semi experiential engineering arithmetic based on the ideology of area ratio , the slope of lift coefficient curve, the zero lift drag coefficient and the induced drag factor of double delta wing aircraft were calculated.

采用基于面积比思想的半经验工程算法计算了双三角翼飞机的升力系数曲线斜率、零升阻力系数和诱导阻力因子。

We call this form of drag induced drag because it is "induced" by the process of creating lift.

我们叫这种阻力叫诱导阻力是因为它是在产生升力的过程中产生的。

Wave drag is more complicated than induced drag and parasitic drag.

我的译文：波阻要比诱导阻力和寄生阻力复杂得多。

This paper presents a mathematical model that employs momentum method to calculate the aerodynamic drag of the truck. This model achieves higher precision than previous methods without consideration of induced drag.

本文提出了动量法计算汽车气动阻力的数学模型，该模型克服了此前的方法中忽略诱导阻力的缺点，显著的提高了计算精度。

But for a small vehicle, the decrease in induced drag and increase in skin friction drag are more equal, so only marginal improvements in overall efficiency are possible.

但是对于小型飞行器，减少的诱导阻力和增加的表面摩擦阻力大致相等，所以效率的提升并不显著。

As a result, the total lift acting on the airplane is more for a given AOA; therefore, the resultant induced or trim drag is reduced.

因此，作用在飞机上的总的升力就要比作用在保持指定攻角上的多得多；所以，综合诱导阻力或者是配平阻力就降低了。

A tail thus enables the bird to have wings that are optimized for cruising speed (with the tail furled to minimize drag) and, at low speeds, the spread tail reduces induced drag during manoeuvring and turning flight.

一条尾巴，从而使鸟类有翅膀是优化的巡航速度（与尾巴furled ，以减少阻力），并在低速，传播尾巴减少诱导阻力在操纵，把飞行。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
