  2. The orientation of the principal stresses relative to the directions of the polarizer and first quarter-wave plate is of course immaterial.

    主應力相對于起偏鏡和第一個四分之波片方向的方位，當然是無關緊要的。
  3. A two - dimensional plain strain finite element model of infinite plate is developed to investigate the ultrasonic wave propagation and scattering on three kinds of cracks : parallel to the surface, 450 oblique angle to the surface, and quarter - circle

    摘要建立了無限長板的具有吸收邊界的二維平面應變有限元模型，在研究了脈沖超聲波在無限長板中傳播的基礎上，對板中平行於表面的裂紋、與表面成45的斜裂紋和四分之一圓周弧形裂紋三種情況的脈沖超聲波散射進行了重點研究。
  4. The directions can be obtained by removing the quarter-wave plate and following the procedure for plane polarized light or by interpolation.

    可將四分之一波片卸去，並按平面偏振光法或內插法來決定其主應力方向。
  5. Biology, etc. owing to many merits has not yet been used to measure parameters of gratings. the paper researches on the subject in view of current lack of it. the main tasks of the paper include : analyzing ellipsometric characteristics of gratings in detail with vector diffraction theory and ellipsometrics ; devising a reflective quarter wave plate at normal incidence according to some ellipsometric characteristics ; making use of normal simplex algorithm during ellipsometric inversion of gratings parameters, inversing ellipsometric parameters with gaussian noise of different standard deviations to simulate actually measured values with examples of isotropic metallic and anisotropic step gratings and testing that ellipsometry about gratings parameters is feasible with the range of certain precision ; discussing choice of incidence angle at length

    本論文的主要工作包括：結合光柵的矢量衍射理論和薄膜的橢偏理論，詳細分析了光柵的橢偏特性；並且根據一些橢偏特性設計出一款正入射反射型單波長1 4波片；在光柵參數的橢偏反演中，引入正單純形法作為反演演算法，分別以各向同性的正弦形金屬光柵和各向異性的階梯型光柵為例，在標準橢偏值的基礎上加入不同偏差的高斯噪聲來模擬實際的橢偏測量值進行反演，在一定精度范圍內得出滿意的光柵參數，說明光柵參數的橢偏測量是可行的；還就入射角的選取問題進行了一定的探討。
