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。In order to compare the retention time ( rt ) and limits of detection of 20 organophosphorous insecticides in different conditions the experiments were carried out using a medium polar capillary column ( db - 1701 ) and a no polar capillary column ( db - 1 ) with two detectors ( gc - fpd and npd ). the rt of 20 organophosphorous insecticides in two different polar capillary columns was a retention qualitative method for 20 organophosphorous insecticides. db - 1701 capillary column coupled with gc - fpd detector was used in the following study, the limits of detection were in range of 5x10 - 11 ~ 2x 10 - 12 g, the linear range was 2x 10 - 9 ~ 1 x 10 - 11g

基於上述的接觸理論和接觸分析結果，本文在最後一部分中分別利用動力時程法和反應譜法對百色水電站尾水渠的巖質邊坡進行動力響應分析，兩者計算方法得出比較一致的結果，同時採用動力摩擦接觸理論重點分析了斷層對于邊坡的穩定影響，認為斷層的存在會使得巖坡的穩定性降低，在地震等動力荷載的作用下對于斷層將發生張開、閉合和錯動現象，尤其是動力荷載和其他荷載如滲流力等的耦合作用將會對斷層產生極為不利的後果，進而影響巖坡的整體動力穩定，應該要引起足夠的重視。In this thesis, the spectral characteristics of a fiber grating are analyzed by using the coupled mode theory. the influences of various structural features such as the length, chirp, coupling coefficient and aperdization to the spectral characteristics were studied numerically with a transfer matrix method. the reflective spectral responses for fiber bragg gratings with different aperdization are analyzed, and the optimal aperdization is ob tained
