defect concentration 解釋
缺陷密度
  • defect : n. 1. 缺陷，缺點，弱點；短處。2. 不足，缺乏。vi. 叛變；逃走。 He defected to the West. 他叛逃到西方。
  • concentration : n. 1. 集中。2. 【化學】提濃，蒸濃，濃縮；濃度；稠密度；【礦物】汰選，選礦，富化。3. 集中注意，專心。
  1. In the third chapter, the influence of current density, solution concentration, erosion time and aging in ambient air on the pl spectra of ps suggests that peak would blue shift with current density increasing, and with erosion time and aging time prolonging ; with the increasing of solution concentration, peaks would red shift when solution concentration less than 1 : 1 but blue shift when solution concentration greater than 1 : 1. above phenomena can be explained by quantum confinement and light center model, but do not deny the action of si - h bonding and defect on the surface in the process of photoluminescence. at present, radiation mechanism is still one of the primary problems in the study of ps

    在第z三章中；通過對比，分析了電流密度、陽極化時間、溶液濃度以及自i然氧化時間對多孔硅光致發光光譜的影響，認為在一定的范圍內，多i孔硅的發光峰位會隨電流密度的增大而藍移，要獲得較強的發光，需z要選擇合適的電流密度；隨著腐蝕時間的延長，多孔硅的發光峰位會i發生藍移；當f酸的濃度較小q ： 1 ）時，峰位隨濃度的增大表現為向i低能移動；而當f酸的濃度較大河山時，峰位隨濃度的增大則表現z為移向高能；多孔硅在空氣中自然氧化；其發光峰位發生藍移，而強i度隨放置時間的延長而降低。
  2. Main research contents and achievements of this thesis is as follows : l. this paper carries through particular test and analysis to the basic physical - chemical properties of gaojiawang palygorskite, an environmental mineral fibre, by xay, ir, tem, sem etc. this paper has also discoursed upon the development appliance research status in quo and directions of palygorskite. 2. according to the preceding surface modification research achievements to nonmetal mineral materials, the author combines the self characteristics of palygorskite such as the ratio of length and diameter, typical nano - rank particle diameter, big ratio surface area, well - developed crystal growth imperfection and lattice defect etc. the author also designs organising modification ortho - experimentation of palygorskite by adopting iso - propyl alcohol as thinner of wd - 51 and ndz - 401, and acquires the best craft parameters and craft conditions for gaojiawang palygorskite original ore organising modification, namely : wd - 51 concentration 1. 6 % ( wt % ), modification temperature 120 ?, and modification time 60 mins ; ndz - 401 concentration 2. 0 % ( wt % ), c modification temperature 120, modification time 80 mins

    在前人對非金屬礦物材料表面改性的基礎上，結合環境礦物纖維?坡縷石自身的特點（如：長徑比、典型的納米粒徑、大比表面積、發育的晶體生長缺陷和晶格缺陷等） ，通過對坡縷石有機化改性設計正交試驗，採用（ ch _ 3 ） _ 2choh作為稀釋劑，獲得了採用wd - 51和ndz - 401對高家窪坡縷石原礦進行有機化改性的最佳工藝參數和工藝條件，分別為： wd - 51的濃度為1 . 6 （ wt ） ，改性溫度為120 ，改性時間為60min ； ndz - 401的濃度為2 . 0 （ wt ） ，改性溫度為120 ，改性時間為80min 。
  3. The charge related to esd can be compensated by oxygen environment, oxygen environment works mainly through making up oxygen vacancy and repairing energy band distortion in time. heating the sample and reducing defect concentration can reduce the charge related to inner defects

    對于樣品表面電子受激解吸造成的充電可通過氧環境提供補償，氧環境主要是通過及時補充氧空位、修復能帶扭曲起作用的；對于電子束調制內部缺陷造成的充電可通過加熱試樣減輕缺陷濃度來補償。
