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
本研究用兩種檢測器（氮磷檢測器和火焰光度檢測器儀器）和兩種不同極性色譜梓（中極性毛細管色譜柱db - 1701 、非極性毛細管色譜柱db - 1 ）作為研究手段，比較了20種有機磷殺蟲劑在兩種色譜柱（ db - 1 、 db - 1701 ） 、兩種檢測器（ fpd 、 npd ）上的保留時間及最小檢測量，建立了用不同極性色譜柱上有機磷農藥的保留時間可作為有機磷農藥雙柱定性確證的的方法；建立了db - 1701 ， gc - fpd測定蔬菜中20種有機磷殺蟲劑的氣相色譜法，該方法的最小檢測量為5 10 ~ （ - 11 ） 2 10 ~ （ - 12 ） g ，線性范圍在2 10 ~ （ - 9 ） 1 10 ~ （ - 11 ） g時，相關性良好。 -
Some helpful conclusions were made. based on the experimental results and theories research, the author put forward some valuable conclusions of this new type of frame - bent structures : ( 1 ) the initial force calculation method considering the lateral torsional coupled ; ( 2 ) the design and construction method of the high - strength concrete frame - bent columns under the high axial compression ratio ; ( 3 ) the construction method of the abnormal joints
在試驗和理論研究的基礎上，提出框排架結構的設計原則和具體的設計方法，主要有以下內容： （ 1 ）考慮平扭耦聯空間整體結構的振型分解法； （ 2 ）針對該類主廠房結構中應用高強混凝土的問題，提出應用高強混凝土的框排架柱的軸壓比限值及相應的構造要求； （ 3 ）對異型節西安建築科技大學博士學位論文點劃分不同區域分別給出其構造要求。 -
The ratio of story shear rigidity as well as the equivalent lateral rigidity ratio of story above the transfer story to the story under the transfer story should be designed properly to avoid the transfer story becoming weak story, thus the shear walls and the columns in the large base will not yield before the elements above the transfer story ; ( 2 ) the translation - torsion coupled effects and the vibration in the plane should be considered in analysis of structure with large base and muti - towers
轉換層的設計除應控制層剪切剛度比外，還應控制轉換層上部與下部結構的等效側向剛度比以避免薄弱層出現在框支層，保證地震作用下落地剪力墻和框支柱不先於轉換層上部結構進入屈服狀態；大底盤多塔樓結構的分析必須考慮平扭耦聯振動和樓板平面內振動的影響。 -
The solutions of examples demonstrated that the optimized synthesis problems of complex distillation system could be solved rapidly with the improved algorithm, and the optimal configurations of thermally coupled ( linked ) side columns, fully thermal coupling column ( petlyuk column ) as well as heat integration between the different columns could be searched automatically
