In the theoretical simulation on the behavior of single helium atom in aluminum, the varieties of energy data including the formation, migration, binding, and dissociation energies for single helium atom at the interstitial, vacancy, grain boundary, and dislocation sites in aluminum lattice were calculated, based on the density functional theories, general gradient approximation and pseudopotential plane wave method. results showed that the most fittable sites for containing helium atoms inside the cell are vacancies. but in the view of the whole lattice, grain boundaries are the best
計算結果表明，晶內he原子擇優佔位區是空位，而在整個晶體范圍，最有利於容納he原子的區域是晶界，位錯容納he原子的能力次於晶界和空位；在fcc -鋁的間隙位中， he原子優先充填四面體間隙位；晶內間隙he原子是可動的，通過間隙he原子的運動，可在晶內聚集，或被空位、晶界、位錯等缺陷束縛。 -
Starting from the designing of software stratification, i firstly introduce the idea of designing the strata of file management and how to realize this idea. then i elaborate in detail the realization of transactional atom operation and the user operation layer, the interface and communication between the realization of different strata ( flowing diagrams and framing designs have been given to some crucial operations ) and the means of realizing the data safety between these different strata

A basic unit of data structure. an atom corresponds to a single record which h as one or more data fields
數據結構的基本單位，一個原子對應于帶有一個或多個數據域的單個記錄。 -
Fabrication of nanostructures based on spm as an extension to spm imaging, referred to as scanning probe nanofabrication ( spn ) is an emerging technique undertaken at labs in the past ten years that comprises manipulation of atom or molecule in a bottom - up paradigm and scanning probe lithography ( spl ) in a top - down paradigm. in chapter one, in the light of decentralized experimental data in this respect, the author, classify in an analytic approach the literature concerned as electrical spl, mechanical spl, thermal spl, and optical spl in terms of different mechanisms of interplay between a probe and a surface of a sample, after describing the most important of this type of microscopy, i. e., scanning tunneling microscopy and atomic force microscopy
由於這項技術的實驗數據比較分散，因此，作者在論文的第一章里首先介紹了掃描探針顯微鏡的兩個最重要的類型，即掃描隧道顯微鏡和掃描原子力顯微鏡的工作原理；然後根據加工方式的不同把它分為自下而上的掃描探針原子（分子）操縱與自上而下的掃描探針刻蝕兩大類；而根據掃描探針與樣品的不同作用機理，對掃描探針刻蝕加工又進行了歸納與綜述，對其特殊的加工方法作了原理性的介紹，並分析了目前存在的共性問題與應用前景。
