In this thesis, three systems, namely, perfect and defect sno _ 2 ( 110 ) surfaces, ti and ru - doped surfaces and the adsorptions of small molecules on above perfect surfaces have been studied in details by using the first - principles method with the combination of pseudopotential plane - wave and atomic basis sets. the structural stability, surface states and the surface chemistry of undoped and metal doped sno _ 2 ( 110 ) surfaces have been discussed, which can provide the theoretical rules to improve the surface properties of this special functional material
為了深入了解sno _ 2表面的電子結構本質及其化學反應性質，本論文採用贗勢平面波和原子軌道基組相結合的第一性原理方法，詳細考察了三種類型體系，即sno _ 2 （ 110 ）完整和缺陷表面、 ti和ru摻雜表面、以及典型小分子在上述完整表面的吸附，揭示了sno _ 2 （ 110 ）及其金屬摻雜表面的構型穩定性、表面態及其對表面化學反應性的影響，為該類型表面功能材料的改性提供理論依據。 -
By examining the vacancy formation energy of three kinds of defect sno _ 2 ( 110 ) surface, the most energetically favorable defect surface is that the surface possesses the coexistence of bridging and in - plane oxygen vacancies, which is different with the traditional defect model by only removing bridging oxygen
通過考察形成三種不同類型sno _ 2 （ 110 ）缺陷表面的缺陷形成能，結果表明，形成同時具有橋氧和面氧缺陷的構型能量上最為有利，這與通常所認為的橋氧缺陷最為穩定不同。 -
Firstly, the basic character of the remote filed eddy current is simulated and analyzed in case of two - dimension axial symmetry which approves the existence of remote filed eddy current phenomenon ; the full circumferential defect model is investigated to approve the feasibility of using the rfec techniques to detect the position and depth of defect ; the pit corrosion 、 circumferential and axial crack models are simulated, and the defect character based on voltage plane polar plot and the changes of phase and amplitude are analyzed to supply the standard for defect reconfiguration
首先，在二維軸對稱情況下模擬與分析了遠場渦流的基本特性，證實了遠場渦流現象的存在;對全周向缺陷的遠場渦流檢測進行了詳細研究，證實了遠場渦流檢測缺陷位置和深度的可行性;對點狀腐蝕、軸向與周向裂紋三種非軸對稱缺陷進行三維有限元模擬，利用相位差和幅值變化曲線與電壓平面極坐標圖對缺陷特徵進行分析，為缺陷形狀重構提供了依據。 -
It is many - sided to create this kind of phase reason, through education person side, as the rational is talked about the error district in the viewpoint, also there is the practice to manipulate defect on the plane. at present how the chinese educational world is living that the chinese is strengthened art education in the education, being living, the clear common understanding goes up wholly incomparably not taking shape theory research and educatees the practice
造成這種局面的原因是多方面的，從教育者一方來說，既有理論觀念上的誤區，也有實踐操作層面上的不足，當前語文教育界應如何在語文教學中加強美育，在理論研究和施教實踐上都遠未形成明晰的共識，有進一步深入探討的必要。 -
Based on the numerical heat transfer, a numerical simulation on the two dimension temperature distribution of a plane with two kind of defects had been done, and studied the reconstruction of defect according to the simulated temperature distribution theoretically
摘要在數值傳熱學的基礎上，從理論上對材料內部熱阻性、熱容性兩類缺陷的平板進行了二維溫度場的數值模擬，並根據模擬的溫度場，對缺陷進行了模擬再現研究。
