  2. The analyses given in this paper to quasi - three - level for 946 nm laser are complete. the relation between 946 nm laser transmission and optimal crystal length has been derived from the rate equations describing the population inversion and the photon density in the laser cavity in the steady - state case. the minimal claims to coating have been given on the base of contrasting 946 nm transmission with 1064 nm transmission in the condition of different cavity losses and how the pump beam radius in the laser crystal and optimal crystal length affect the laser threshold and output power of 946 nm laser has been given as well

    對產生946nm譜線的準三能級結構給出了較為完整的分析，利用激光諧振腔處于穩態時的速率方程，導出了準三能級nd ： yag946nm起振時，透射損耗與最佳激光晶體長度的關系，在與1064nm透射損耗相比較的基礎上，給出了不同的腔損耗情況下的最低鍍膜要求，並且給出了激光閾值、輸出功率和最佳激光晶體長度及泵光光斑大小的關系，這為設計室溫下高效運轉的946nm激光器的提供了理論基礎，這種分析方法對研究此類低增益，準三能級或三能級激光系統輸出特性有借鑒意義。
  3. The spectrum only depends on the temperature of the object. if the temperature is low, the peak of the spectrum is at red region. for higher temperature, the peak shifts towards the yellow, blue, finally in the ultraviolet region

    光譜曲線的形狀只取決於物體的溫度，溫度低的物體光譜峰值在紅光，溫度越高，峰值越向短波長一端偏移，由黃光開始，到達藍光，再進入紫外線區域。
  4. The worm - like mesoporous materials were synthesized and characterized with tem, x - ray diffraction, nitrogen adsorption / desorption and ft - ir techniques, etc. the results showed that all the samples had larger porediameter than the samples through calcinations under resembled conditions, but the mesopore ordered poorly. ft - ir results showed hexagonal structural character were kept, but xrd, tem results showed that the samples have the structure characteristics of msu - x. it was analysized that all n2 adsorption isotherms of the samples belong to langmuir iv category which is related to mesoporous materials

    Ft - ir光譜表徵結果顯示，經萃取處理后的介孔sio _ 2材料保持了六方的結構特徵；經xrd 、 tem進一步分析，證實所合成的介孔氧化硅材料具有msu - x材料的結構特徵， xrd譜圖表明樣品具有短程有序性：所合成的材料低溫n _ 2吸附測試結果表明，各樣品的n _ 2吸附等溫線均與中孔（介孔）特徵的第類曲線基本相符；由kelvin公式計算得到的孔徑分佈曲線說明，介孔材料具有較為集中的孔徑分佈；各樣品的bet比表面積比較高。
  5. Also shown by afm images are the regular features of crystals and ordered crystal domains for the film grown on 200 substrates, the morphologies indicate a phase transition, which is clearly confirmed by contrast between ( 0, 0 ) and ( 0, 1 ) absorption features and the bathoshift of ( 0, 0 ) absorption peak corresponding to the temperature of the substrate

    Afm圖像同時顯示，在200的襯底上生長的薄膜具有規則的晶體外型和有序排列的微疇，說明存在結晶轉變。 f - ptcdi薄膜的吸收光譜的（ 0 ， 0 ）和（ 0 ， 1 ）性狀的強度對比與紅移程度隨襯底溫度的變化清晰地表現出150到200之間存在一個相變， dsc測試說明該轉變是從低有序到高有序度的轉變。
  6. With the rapid development of optical fiber communication technology, low - cost and high quality near inferred laser and light emitted diode working at room temperature become widely available. the emit wavelength from these light resource is not only consistent with the three low - decay windows of fiber optics, but also with many wide - frequency or recombination absorption spectrum of environmental and industrial gases

    光纖通信技術的發展使相對低價、工作于常溫、高質量的近紅外激光和發光二極體可廣泛獲得，這些發光光源的發射波長與光纖的三個低損耗窗口相一致，也與許多環境和工業氣體的泛頻或復合吸收譜線相一致。
  7. In part four, the results of cryogenic raman spectra investigation show temperature dependence of rbm and gm at low temperature is greatly different from at high temperature, and the intensity of most feature is not reversible at low temperature

  8. Moreover, the sio2 / tio2 composite thin film showed the lowest pl intensity due to a decrease in the recombination rate of photo - generated electrons and holes under uv light irradiation, which further confirmed the film with the highest photocatalytic activity at 700 c. when the calcination temperature was higher than 700 c, the decrease in photocatalytic activity was due to the formation of rutile and the sintering and growth of tio2 crystallites resulting in the decrease of surface area

    同時，此時sio _ 2 / tio _ 2復合薄膜的熒光光譜顯示最低的熒光強度，這表明此時薄膜中的光生電子和空穴的復合速率最低，因而更有利於物質的光催化降解。當熱處理溫度高於700時，武漢理工大學碩士學位論文薄膜的光催化活性下降，這是由於薄膜中晶相二氧化欽的燒結和成長導致樣品的表面積下降以及金紅石相的形成。
