  1. A rude noise broke on these fine ripplings and whisperings, at once so far away and so clear : a positive tramp, tramp, a metallic clatter, which effaced the soft wave - wanderings ; as, in a picture, the solid mass of a crag, or the rough boles of a great oak, drawn in dark and strong on the foreground, efface the aerial distance of azure hill, sunny horizon, and blended clouds where tint melts into tint

    一個粗重的聲音，沖破了細微的潺潺水聲和沙沙的風聲，既遙遠而又清晰：一種確確實實的腳步聲。刺耳的喀嗒喀嗒聲，蓋過了柔和的波濤起伏似的聲響，猶如在一幅畫中。濃墨渲染的前景一大塊峭巖或者一棵大橡樹的粗壯樹干，消融了遠景中青翠的山巒明亮的天際和斑駁的雲彩。
  2. 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。
  3. But, at the noise i made, the snake let himself flow easily across the sand like the dying spray of a fountain, and, in no apparent hurry, disappeared, with a light metallic sound, among the stones

    可是一聽到我的腳步聲，蛇卻象一股乾涸了的水柱一樣，慢慢鉆進沙里去。它不慌不忙地在石頭的縫隙中鉆動著，發出輕輕的金屬般的響聲。
  4. No disturbing noise and metallic dusts

    沒有噪音，操作員不會接觸金屬微塵粉
  5. Abstract : metallic foam or porous materials were developed at the end of the 80 " s and applied to industry at the beginning of the 90 " s. they have excellent physical properties, especially damping characteristis, so they are widely used for vibration insulation, noise elimination, electromagnetic screening and so forth. a description is given of the “ casting and foaming ” method for the fabrication of these metallic foams, and a detailed account of their mechanical and damping properties

    文摘:金屬泡沫或金屬多孔材料是80年代後期國際上迅速發展起來的一種物理功能與結構一體化的新型工程材料.它所具備的多種優異物理性能特別是阻尼性能已引起廣泛關注，並在消聲、減震、分離工程、催化載體、屏蔽防護、吸能緩沖等一些高技術領域獲得了廣泛應用.文章著重介紹了鑄造發泡法製造鋁泡沫材料的技術難點.對金屬泡沫材料的力學性質和阻尼特性進行了詳細介紹.為金屬泡沫材料開發、應用提供基礎知識和信息
