  1. We consider that the complexes of bmon ( m, n > 1 ) or the point defects induced by heavily boron doping may be involved in the nucleation of oxygen precipitates at high temperature range of crystal cooling. therefore it is reasonably deduced that the density of voids in hb cz silicon increases and the size of voids decreases due to the reduction of vacancy concentration as a result of heavy boron - doping enhanced oxygen precipitation prior to the void formation

    在實驗事實的基礎上，我們認為在重摻硼硅單晶生長過程中， bmon （ m ， n 1 ）復合體或摻b引起的點缺陷能在晶體冷卻過程中的較高溫度階段形成，且在隨后的退火過程中能穩定存在，作為氧沉澱形核的核心，從而促進了氧沉澱，減小了大直徑硅單晶中void缺陷的尺寸，增加其密度。
  2. The chemical composition, micro - structure and optical properties and its application of tio2 thin films deposited on k9 glass by using reactive electron - beam evaporation ( reb ) are studied through sem, tem, xps, xrd, spectroscopic ellipsometry ( se ) and uv - vis spectrophotometer in the dissertation, and the progresses of nucleation and growth of thin film are discussed from the point of view of dynamics and thermodynamics so that a structure model of tio _ ( 2 ) thin film is brought forward

    本文採用sem 、 tem 、 xps 、 xrd 、橢圓偏振儀（ se ） 、 uv - vis分光光度計等分析手段系統地研究了電子束反應蒸發方法在k9玻璃上制備tio _ 2薄膜的成分、結構和光學性能以及tio _ 2薄膜在光學多層膜中應用，並開發了膜系設計軟體。文中還從動力學和熱力學角度分析了tio _ 2超薄膜的形核生長過程，得出了tio _ 2薄膜的組織結構模型。
  3. The results show that in the later stage of the nucleation process, the maximum slip velocity is monotonically accelerating ; the slipping hot spot ( where the slip rate is maximum ) migrates spontaneously from a certain instant, and such migration is spatially continuous ; when the maximum velocity reaches a detectable order of magnitude ( at least one order of magnitude greater than the loading rate ), the remaining time is 20 hours or more, and the temporal variation of slip velocity beyond this point may be used as a precursory indicator ; the average slip velocity is related to the remaining time by a log - log linear relation, which means that a similar relation between rate of microseismicity and remaining time may also exist ; when normal stress variation is taken into account, time scale of such processes can be extended by about 2 times

    結果表明，在成核的後期階段：最大位移速率單調加速增加；滑動熱點（最大滑動速率處）在後期階段開始自發性遷移，且在空間上連續；當最大滑動速率達到可以明顯探測的量級時（高於載入速率一個數量級以上） ，倒計時間為20小時或更長一些，這時的速率變化可作為臨震預測標志；平均滑動速率與倒計時間的關系在臨震階段呈對數線性趨勢，由此可推測微震活動增長率與倒計時間同樣存在對數線性關系；正應力的變化對上述時間尺度有延長作用，使之大致增加到原數值的2倍。
  4. It considers point, line and interfacial defects in the context of structural transformations including annealing, spinodal decomposition, nucleation, growth, and particle coarsening

    其中會討論在退火、旋節點分解、成核、成長以及粒子粗粒化等結構轉變之過程中，所涉及的點、線和面的缺陷。
