fluorescence stability 解釋
流動穩定性
  • fluorescence : n. 熒光(性)。
  • stability : n. 1. 穩定,穩定性,穩度。2. (船等的)復原力。3. 鞏固;堅定,持久不變。
  1. It measures the density of oxygen by detecting the life - span of the fluorescence quenching. the so - called fluorescence quenching is a kind of physics or chemistry process that the fluorescence material has chemical or physical reactions with certain substance is selected here. it has the advantage of good stability of fluorescence, long life span and the strong quenching effect

    本課題光纖氧氣傳感器檢測系統是基於熒光猝滅效應的檢測機制,通過測定熒光壽命從而檢測氧氣濃度的,熒光猝滅效應所引起的熒光壽命具有很好的穩定性、猝滅效果以及系統使用壽命長。
  2. On the backgrounds of researches inside and outside country, and cooperating experiments with theories analyses, the influence of different processing technology parameters and different sbs modifier sorts on the sbs modified asphalts " properties has been studied. at the same time, their microstructure are observed through fluorescence optical microscopy and scanning electronic microscopy, thus to direct modified asphalt production. on the above conclusion ' s basement, analysing some disadvantages of the storage stability test of sbs modified asphalt in the current specification, a new storage stability test apparatus is developed

    本文在參考國內外研究的基礎上,採用理論、試驗相結合的方法,研究加工工藝參數以及改性劑種類等對sbs改性瀝青性能的影響,並通過熒光顯微鏡、掃描電鏡分析其微觀形態,從而指導sbs改性瀝青的生產;在此基礎上,分析我國現行規范用來評價sbs改性瀝青儲存穩定性方面的不足,開發了新的試驗儀,根據動態剪切流變試驗結果和微觀狀態分析,提出一個新的指標? ?離析率r _ s來評價sbs改性瀝青的儲存穩定性;最後,針對不穩定的改性瀝青提出改善措施,研究證明摻加增容劑和穩定劑是行之有效的方法。
  3. The oxygen sensing properties of the membranes have been studied, the results indicate that the membranes with ru ( phen ) 3cl2 have better oxygen - sensitivity than those with ru ( bpy ) 3cl2, and the membranes with the formamide content of 16 % ( v / v ) and ru ( phen ) 3cl2 content of 2. 10g / l in the precursor mixture have the best structure and quality. the fiber optic gas oxygen sensor with this sensing membrane has a detection limit of 5ppm, a response time of less than 30s, excellent reproducibility and stability. ( 2 ) a new kind of organically modified oxygen - sensitive membrane based on fluorescence quenching was prepared by sol - gel method, using dds and teos as the mixed precursor, rufchenbcla as the indicator

    實驗證明:該類敏感膜的tan _ 0 tan值與氧氣濃度存在良好的線性關系;包埋ru ( phen ) _ 3cl _ 2的凝膠膜的氧敏感性相對較好;當甲酰胺為16體積比含量, ru ( phen ) _ 3cl _ 2在前驅體中濃度為2 . 10g l時,制備的敏感膜結構和性能最佳;對氣態氧檢測時,該敏感膜的響應時間小於30秒,檢測下限為5ppm ,具有較好的重復性和穩定性。
