  2. Ultraviolet absorption detector, photodiode array detector ( dad ), fluorescence detector, and electrochemical detector are optional detectors, response value of which is relative to not only quality of the object under test, but also structure of the compound ; refractive index detector and evaporative light - scattering detector are universal detector, responding to structure of all compounds ; evaporative light - scattering detector is quality - type detector, whose responding value only relates to quality of the object under test for compounds with similiar structures ; photodiode array detector ( dad ) can, at the same time, record absorption spectra of the object under test in a prescribed wave scope, consequently, it can be used in spectrum control and inspection of purity of chromatographic peaks of the object under test

    紫外、二極體陣列、熒光、電化學檢測器為選擇性檢測器，其響應值不僅與待測物的質量有關，還與化合物的結構有關；示差折光檢測器和蒸發光散射檢測器為通用型檢測器，對所有的化合物結構均有響應；蒸發光散射檢測器屬質量型檢測器，對結構類似的化合物，其響應值幾乎僅與待測物的質量有關；二極體陣列檢測器可以同時記錄待測物在規定波長范圍內的吸收光譜，故可用於待測物的光譜管制和色譜峰純度的檢查。
  3. Was released, which was confirmed by molecular mass and amino acid composition analysis. ultraviolet and circular dichroism spectra were used to test the secondary structure of - mt - 3. distinct from other - mt, - mt - 3 showed a negative trough at about 220nm in the cd spectrum, suggesting that an - helix might exist in its secondary structure

    紫外吸收光譜及圓二色性光譜研究重組- mt - 3的結構。 mt - 3的與其餘mt的結構域不同， - mt - 3的圓二色性光譜在220nm左右為負峰，說明- mt - 3可能包含一個-螺旋的二級結構。
  4. The distributions of various glands and their sizes and densities on leaves have also been observed. combining with the data obtained from ultraviolet spectra, it has been concluded that hypericin does not exist in sect ascyreia and sect spachinm. hypericin is only limited to sect hypericum and sect adenosepalum

    還觀察統計了各類腺體的分佈及在葉片上的大小、密度，結合紫外光譜，總結提出的金絲桃組和地耳草組植物不含金絲桃素、金絲桃素僅局限分佈於貫葉連翹組和遍地金組的結論，具有典型的植物化學分類意義及藥材品質評價意義。
  5. Preliminary observation on ultraviolet emission spectra in non - equilibrium 2 - d hypersonic blunt body shock layer flow

    二維高超聲速鈍體激波層紫外輻射的實驗觀察
  6. The molecular weight distributions, infra - red, ultraviolet and nuclear magnetic resonance spectra for the polysilane polymers have been described

    本文還討論了這些聚硅烷的分子量分佈以及紅外、紫外、核磁共振等光譜性質。
  7. We also have analyzed the photoluminescence ( pl ) spectra of some zno films, it turns out that the emission of ultraviolet light comes from the radiative recombination of excitons within nano - crystal energy band - gap, and the pl peaks move to smaller wavelength because zn are substituted by fe, co, and cu, which cause the size of the film grains smaller and the effective band - gap bigger. the red emission of zno films is due to, on the one hand, decrease of the film grains size which causes the emission intensity smaller and smaller until it disappears abruptly, on the other hand, the transition of electrons from deep donor level of the oxygen vacancies to the valence band

    另外，我們還對薄膜光致發光性質進行了分析和研究，結果表明：納米結構zno薄膜的紫外發光來源於帶間激子的輻射復合發光， pl譜的帶邊發射峰發生藍移是由於fe 、 co 、 cu對zn的替代使薄膜粒子的尺寸減小，使薄膜的有效帶隙增寬； zno薄膜的紅色發光，一方面是zno顆粒尺寸的減少，帶間的激子發射峰越來越弱直至猝滅，另一方面主要是與zno晶格中的o空位有關，由深能級復合發光引起紅光發射。
  8. The infrared results showed that the ir characteristic value l080cm - lof cubic crystal sio, and the absorption peak 460cm - l of mgf, caused by the interaction between f - - mg ' + - p elastic vibration and photon radiation, appeared in the ir spectra. ellipsometric analysis showed that the typical absorption peaks 58lnm, 589nm and 606nm, resulting from the surface plasma resonance of cu panicles and reflecting the absorption on composite film system, appeared in the extinction coefficient k curves of cu ( voll5 % ) mgf, cu ( vol20 % ) mgf, and cu ( vol30 % ) mgf, cermet films, respectively. with the component of cu increasing, the peak site presented red shift, which was in accordance to the results of ultraviolet - visible spectra

    橢偏測試分析表明： cu （ vol15 ） mgf _ 2 、 cu （ vol20 ） mgf _ 2和cu （ vol30 ） mgf _ 2樣品的消光系數k曲線中出現了反映復合金屬陶瓷體系吸收的由cu金屬顆粒表面等離子體共振引起的吸收峰，峰位分別為581nm 、 589nm和606nm ，呈現紅移，這些與紫外-可見光譜測試結果相一致；此外， cu - mgf _ 2復合納米金屬陶瓷薄膜光學常數的實驗值與考慮尺寸效應修正過的mg理論值總體上符合得很好。
