  7. Modern museum reported to the police that one of the most expensive paintings was gone

    （現代藝術館一幅館中最名貴的畫不翼而飛，而館方也馬上向警方報了案。
  8. But when there is enough space, the faravahar is shown in all of its glory, with kingly figure, disc, streamers, and many - feathered wings

  9. The graphic evolution from the spread - eagle is evident in the stylized assyrian version of the design, where the bird ' s legs are abstracted into wavy streamers on either side of the disc which end either in claws or in scrolls, as they do in the persian design

    從展翼鷹演進而來的圖案明顯地在程序化了的亞述人版本的圖案裏面，鳥的腳伸展到圓盤的方向，或者腳爪的方向的波狀橫幅上，雙或者成卷形，與波斯人的圖案一樣。
  10. This method makes it possible for investigating the unsteady nonlinear potential flow in a complicated environment with higher efficiency. the aerodynamic forces of a wing in couple motion of heave and pitch with ground effect are analyzed in detail based on the numerical result. it is shown that a thrust force exists when the wing is in heave motion

    深入系統地分析了存在表面效應時機翼運動規律和氣動力之間的關系，研究結果表明，機翼升沉運動產生的推力與升沉速度幅值的平方成比例，推力和推進效率和振蕩頻率成反比；機翼的俯仰運動可以調節推力和推進效率，但是單純的俯仰運動不會產生推力。
  11. In the examples we get some evolution curves, such as the growth rates and shape functions, which are used to analyze the stability problems for the boundary layers of the fuselage and the wing

    算例給出了擾動幅值增長和形狀函數等演化曲線，並對機翼、機身的邊界層穩定性進行了分析和研究。
  12. Stiff struts and ribs meant that wings were too rigid to flex much torsionally, so builders installed ailerons ? flaps located on the outer, trailing - edge portions of wings

    難以彎曲的支柱和翼肋，使得機翼太過剛硬，同時也限制了扭轉幅度，因此工程師加上了副翼，也就是位於機翼后緣外側的襟翼。
  13. Most wings extend from the fuselage at a fixed angle, and they are sufficiently rigid that they do not move or twist much in flight ? certainly a reassuring feature for pilots and passengers alike

    機翼與機身大多成固定角度，同時具備足夠的剛性，使機翼在飛行中的擺動或扭轉幅度不致過大，這一點對飛行員和乘客來說都相當重要。
