. 精品晶体缺陷及其对材料性能的影响摘要 :所有的天然和人工晶体都不是理想的完整晶体，它们的许多性质往往并不决定于原子的规则排列， 而决定于不规则排列的晶体缺陷。 晶体缺陷对晶体生长、晶体的力学性能、 电学性能、 磁学性能和光学性能等均有着极大影响，在生产上和科研中都非常重要， 是固体物理、固体化学、材料科学等领域的重要基础内容。研究晶体缺陷因此具有了尤其重要的意义。本文着重对晶体缺陷及其对晶体的影响和应用进行阐述，以适应人们不同的实际需要和时代的发展需求。关键词 :晶体缺陷; 性能Crystal defect and it’s influence on the material propertiesAbstract All of the natural and artificial crystal is not ideal complete crystal, many of their properties are not always decide to the rules of atoms to arrange, but decide to the irregular arrangement in the crystal defect. Crystal defect have anenormous influence to crystal growth, mechanical properties of crystal, electrical properties, magnetic properties and optical properties, etc, they are very importantin the production and research, It is important content. to a basis research in the field of crystal defect,such as solid physics, chemistry, material science,and so on. it so has been particularly important significance to solid. In order to adapt to the different actual needs and the development of The demand of Times.of people.This paper focuses on expounding the influence and the application of the crystal defect and its impact on the crystal.Keywordcrystal defect property. 精品1. 引言很早以前 , 金属物理学家在研究金属的加工变形时就发现了晶体缺陷与金属的变形行为及力学性质有密切的关系。后来, 材料科学家发现这类缺陷不仅控制着材料的力学性状, 而且对材料的若干物理性质(如导电性、 导热性等 ) 有直接的影响, 故在冶金物理学和材料科学领域里逐渐发展了晶体缺陷理论。在地学界, 近10多年来人们开始认识到晶体的塑性变形完全取决于晶体缺陷, 即矿物岩石在塑性流动过程中晶体缺陷起着控制性的作用...
