| 摘 要： | 晶体具有极其规则的原子结构.然而,大多数晶体物质不是完整的,原子排列的规则图像被晶体缺陷所破坏.本文列举不同类型的缺陷:点缺陷(空位、间隙离子、置换离子、反位缺陷、拓扑缺陷、Schottky缺陷和Frenkel缺陷)、线缺陷(位错)、面缺陷(颗粒边界、小角晶界、反相畴和堆垛层错)和体缺陷(空洞和析出物).

| Abstract: | Crystalline solids have very regular atomic structures.However,most crystalline materials are not perfect,the regular pattern of atomic arrangement may be interrupted by crystal defects.The various types of defects are list here:point defects(vacancies,interstitial atoms,substitutional atoms,antisite defects,topological defects,Schottky defects,Frenkel defects),Line defects(dislocations),planar defects(grain boundaries,anti-phase boundaries,stacking faults),bulk defects(voids,precipitates). |
