  1. 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。
  2. Another possible reason for this phenomenon is that with higher temperature, the mobility near defects of carbon atoms in grown carbon nanotubes would be also elevated, which gave carbon atoms higher mobility and have chance to readjus to decrease or eliminate some defects. a series of pretreatments and modifications including purification, annealing and doping were performed before hydrogen storage experiments carried out at room temperature under modest pressure ( 12mpa )

    在氮氣中進行退火處理納米碳管的儲氫性能高於在空氣中退火的納米碳管，主要原因是在空氣中退火時，納米碳管的表面引入了大量的氧官能團，而氧官能團能夠占據納米碳管的缺陷位，減少了氫的可吸附位置，阻礙氫進入納米碳管，從而降低了納米碳管的儲氫能力。
  3. The oxygen content in the vent pipe of the equipment has to be checked for the concentration of o2 to get the required amount of nitrogen

    需要檢查設備放空管線中氧氣的濃度，來確定所需要的氮氣的量。
  4. Asthma is an inflammatory airway disease. professor leung ting fan of the department of paediatrics said that in the past, it is very difficult to assess the degree of airway inflammation directly. medical research has found that inflammation of the airways will increase the level of nitric oxide in the exhaled breath of the patients

    新的量度氣管發炎程度的方法亦加強了對哮喘的監察，兒科學系梁廷勛教授表示，哮喘是一種氣管炎癥，過去我們很難直接知道氣管發炎的程度，不過醫學研究顯示，氣管發炎會讓患者呼出的一氧化氮增加。
