准晶晶体材料研究尹显富内容提要：准晶体结构自 1984 年被报道以来，因其与传统晶体周期性不相容的特殊结构，引起各国学者的极大兴趣。对准晶材料性能及应用研究结果表明，准晶材料因独特的结构而具有独特的性能，但由于材料科学迅猛发展，新材料层出不穷，而准晶材料所具有的一些优异的性能， 能满足一些实际应用中传统材料所不能满足的要求。因此，了解其发展历程、掌握其理论基础、研究现状及其发展前景 ，对于研究开发能应用于实际生活、生产的准晶材料有着重要意义，这是本题的主要内容。关键词：准晶材料 物理性质 性能 准晶结构 The physical properties of quasicrystalline materials and research progressYinXianfuAbstract: Quasi-crystal structure has been reported since 1984, because of its incompatibility with traditional periodic special crystal structure, causing great interest scholars from different countries. Alignment of crystal material properties and applied research results show that because of the unique quasi-crystalline structure of materials with unique properties, but because of the rapid development of materials science, new materials emerging, while the quasi-crystalline material with some of the excellent performance, to meet some practical applications of traditional materials can not meet the requirements. Therefore, understanding the development process, to grasp its theoretical basis, research status and development prospects for the research and development can be applied in real life, the production of quasi-crystalline materials is of great significance, which is the main content for this question.Keywords: Quasicrystal Physical properties Performance Quasicrystals目 录绪论准晶材料作为一种新兴材料，自从 1982 年准晶（Quasicrystal）的发现至今，有关什么是晶体的辩论一直没有中断。我们知道，传统的晶体学基于晶体微观结构的周期性，晶体是绝对不会出现 5 次和高于 6 次对称轴的。准晶的电子衍射图居然出现了 5 次对称，只好给这个新生儿起了个“...
