【正文】 :所有的天然和人工晶體都不是理想的完整晶體，它們的許多性質(zhì)往往并不決定于原子的規(guī)則排列，而決定于不規(guī)則排列的晶體缺陷。晶體缺陷對晶體生長、晶體的力學(xué)性能、電學(xué)性能、磁學(xué)性能和光學(xué)性能等均有著極大影響，在生產(chǎn)上和科研中都非常重要，是固體物理、固體化學(xué)、材料科學(xué)等領(lǐng)域的重要基礎(chǔ)內(nèi)容。本文著重對晶體缺陷及其對晶體的影響和應(yīng)用進(jìn)行闡述，以適應(yīng)人們不同的實(shí)際需要和時(shí)代的發(fā)展需求。 性能Crystal defect and it’s influence on the material propertiesAbstract All of the natural and artificial crystal is not ideal plete 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 an enormous influence to crystal growth, mechanical properties of crystal, electrical properties, magnetic properties and optical properties, etc, they are very important in 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 paper focuses on expounding the influence and the application of the crystal defect and its impact on the crystal.Keyword crystal defect property1. 引言 很早以前, 金屬物理學(xué)家在研究金屬的加工變形時(shí)就發(fā)現(xiàn)了晶體缺陷與金屬的變形行為及力學(xué)性質(zhì)有密切的關(guān)系。在地學(xué)界, 近10多年來人們開始認(rèn)識到晶體的塑性變形完全取決于晶體缺陷, 即
