Using the directional derivative formula, the governing equation is discreted in the physical domain in which a nonorthogonal grid system is used. Two kinds of AF2 schemes, i. e. AF2-plane relaxation and full implicit AF2, for the TSD equation are proposed. Numerical results show that the full implicit AF2 scheme converges faster than AF2plane relaxation scheme. For the rectangular wing and swept wing, the results of the present method are compared with FP results, and the agreement is good.

采用适合于梯形机翼和后掠机翼的斜网格，利用方向导数公式直接在物理空间对主管方程进行离散；将近似因式分解方法应用于绕机翼的跨音速小扰动势流问题，提出AF2—面松弛和AF2全隐式两种迭代格式，并对它们的收敛速度进行比较，结果表明后者明显快于前者；直机翼和后掠机翼的算例表明，本文方法的结果与精确势流方法的结果吻合良好。

A calculating method to determine the clearance size of the rudder face along the extension direction of the swept-back wing for airplane is presented, which can be used for calculating the clearance size of the rudder face at limiting deflection angle, and point out that several parameters for determining the caearance is essential .

本文针对某型无人机翼面、舵面设计，首先导出了一种确定后掠翼舵面展向缝隙尺寸的计算方法，使用该方法能够定量地计算舵面在极限偏转角下缝隙的尺寸，并指出决定舵面缝隙大小几个主要参数，为舵面缝隙设计提供了可靠依据。

If the wing is also swept, the forward wing will also cause more rolling moment than the other wing due to the greater moment arm of its center of lift as well as the increased lift.

如果翼也席卷，远期翼也将造成比其他机翼因更大的力臂其升降机中心，以及增加更多的滚动电梯的时刻。

This paper investigates a new flow control technique based on a forward-swept wing blended body tailless configuration by a wind tunnel.

通过风洞实验，研究了基于前掠翼融合体无尾气动布局的一种新概念流动控制技术。

Viscous flows around an infinite span untapered swept back wing at high angles of attack are investigated numerically by solving the quasi two dimensional Navier Stokes equations to deal with the effects of the swept-angle on the flow structure and force behavior.

通过数值求解Navier Stokes方程，研究了无限翼展直后掠翼在不同后掠角下的大迎角粘性分离流，探讨了后掠角对流场结构和升阻力特性的影响。

Dutch roll is a combination of yawing and rolling motion that is characteristic of all swept wing aircraft.

荷兰滚是一个偏航和滚动运动是所有掠翼飞机的特点相结合。

"Later airplane design was affected by the development of the jet engine; most airplanes today have a long nose section, swept-back wing s with jet engines placed behind the plane's midsection, and a tail stabilizing section."

后来飞机设计受喷射发动机的发展影响，大部分现代的飞机有一个长鼻机身，向后斜的机翼带有喷射发动机安置在飞机中段部分，尾部是安定器。

The W-shaped tailless aircraft has not stabilizer and vertical tail,and it is based on the design of forward-swept wing and the integrated design of blended wing-fuselage.

W型无尾飞机基于前掠翼及翼身融合的一体化设计，取消了平尾和垂尾，可大幅降低雷达反射截面积，减轻结构重量；同时具有亚声速气动效率高、横航向操纵面效率高的优势。

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。
