  1. In that sort of half reverie which permits one to participate in an event and yet remain quite aloof, the little detail which was lacking began obscurely but insistently to coagulate, to assume a freakish, crystalline form, like the frost which gathers on the windowpane

    這種迷迷糊糊的幻想狀態既允許一個人置身於一個事件之中又叫他保持冷漠，在這種狀態中那尚未可知的小小細節開始模糊而又執著地凝聚，形成怪異的晶體，像窗子上結的霜，那些霜樣的晶體顯得這么怪誕，這么徹底無拘無束，這么奇形怪狀，然而它們的命運卻要由最最嚴酷的自然法則操縱，而我心中產生的感情亦是一樣。
  2. According to the guidline, two nd : yag lasers have been designed and set up, one is end - pumped by lower output power ld using a selfoc micro lens, and the other is end - pumped by high output power ld using a pair of lenses are designed, and the characteristics such as output power and power stabilization of both solid - state lasers are investigated. thirdly, when an empty liquid crystal cell is inserted in the cavity of the nd : yag laser pumped by high power ld, the laser can operates in single axial mode. finally, according to the relationship between the laser output power and the longnitudinal a ld - end - pumped nd : yag laser sensor for displacement measurement has been investigated theoretically and demonstrated experimently, the results indicate that when the mean radius of pumping inside the laser cavity is far less than that of the oscilating laser mode, the exponential of the output power is a gauss function of the longitudinal positon of focused spot of ld pumping beam, both the measurement range and the sensitivity are dependent on the incident pumping power, as the incident pumping power is increased, the measurement range is enlarged and the sensitivity is improve d

    本文首先介紹了ld泵浦nd ： yag激光器的發展狀況、主要特性及其應用，從四能級速率方程出發，推導了ld泵浦nd ： yag激光器的閾值、輸出功率和斜效率的表達式，並簡述了激光器的工作原理、結構型式和倍頻方法；其次，以空間相關的速率方程為基礎，提出了ld端面泵浦nd ： yag激光器的設計方法，給出了一定泵浦耦合方式下，振蕩光模尺寸、最佳輸出耦合率、泵浦光模尺寸、泵浦光焦斑位置等參數的選取依據，以此為依據，設計了自聚焦透鏡耦合小功率ld泵浦nd ： yag激光器和透鏡組耦合高功率ld泵浦nd ： yag激光器，對激光器的輸出功率和功率穩定性等特性進行了實驗研究；再次，在帶尾纖輸出的高功率ld泵浦nd ： yag激光腔內插入一隻空液晶盒，觀察到了激光器以單縱模運轉；最後，根據泵浦光焦斑端面位置對激光輸出功率的影響規律，提出了ld端面泵浦nd ： yag激光位移傳感新方法，並進行了理論和實驗研究，研究結果表明：當激光晶體內泵浦光平均光斑半徑遠小於振西安理工大學碩士學位論文蕩光束腰半徑時，激光輸出功率的自然指數與泵浦光焦斑的縱向位置成高斯變化規律，測量范圍和靈敏度依賴于泵浦功率，隨著泵浦功率的增加，測量范圍擴大，靈敏度提高，當端面泵浦功率為7 . 24w （最大輸出功率為1 . 926w ）時，激光位移傳感器的測量范圍和靈敏度分別是13 . 045mm和0 . 148mw / pm 。

  4. The temperature from amorphous to crystal of tungsten oxide sol - gel films with catalyst is increased and the reason is in studying. as results of tunnel scan - afm, both pt sputtered tungsten oxide films and pt sputtered tungsten oxide sol - gel films there is distinct and out - of - order parallel line structure on the surface of amorphous. molecules of the sample tend to tetrahedron and the former has more planarer structure

    隧道-原子力顯微鏡測試結果表明:非晶態時，磁控濺射摻鉑薄膜樣品表面和溶膠凝膠摻鉑樣品表面都有明顯的平行線狀結構，長程無序，分子趨於四面體結構，只是前者比後者表面較平整;晶態時，磁控摻鉑樣品在自然生長面上原子呈平面分佈，長程有序，溶膠摻鉑樣品則呈wo6面心結構。
