摘要超导是于1911年荷兰科学家昂纳斯及其科研团队于一次低温实验室中意外地发现。超导体与常规导体最大区别在于七道题内部电阻为零,这是一个具有突破性的发现。同时超导体还具有完全抗磁性。超导体因其这两种特殊的性质,在能源输运行业、航天航空行业、信息工程行业、交通运输行业以及能源储存行业等都有广阔的应用前景。所以自超导问世以后就有很多科学家对炒到的研究做了大量的工作,也不断的完善了人们对超导的认识,并且在超导问世至今的一百年里就有四次年度诺贝尔物理学奖是颁给在超导领域做出突出贡献的物理学家。在各大研究院、各大高校都有大量的研究人员在对其超导体进行研究。随着科技学技术的进步超导体的临界温度也越来越逼近我们的生活,使得我们在日常生活中能看到很多奇妙的超导现象越来越成为可能。本文就对硒化物CsNi2Se2的超导电性进行探索,对其超导电性作进一步的研究。47763 Abstract Superconductivity is a Dutch scientist H. Kamerlingh Onnes its research team in a low-temperature laboratory accidentally discovered in 1911. Superconductor with conventional conductors biggest difference is that the internal resistance is zero seven questions, which is found to have a breakthrough. Meanwhile superconductors also have full anti-magnetic. Superconductors because these two special properties, in the energy transport industry, aerospace industry, information technology industry, transportation industry, and energy storage industries have broad application prospects. So there are a lot since the advent of superconducting Scoop research scientists have done a lot of work, but also continue to improve people's understanding of superconductivity, and the advent of a hundred years, there has been four years in the superconducting Snow Bell Prize in Physics is awarded to outstanding contributions in the field of superconductivity physicist. Institute in the major, major colleges and universities have a large number of researchers in the study of its superconductor. With the critical temperature superconductor technology advancement techniques are increasingly approaching our lives, so that we can see in everyday life many wonderful phenomenon of superconductivity is becoming possible for this paper diselenide CsNi2Se2 superconductivity explore for further study of its superconductivity. 毕业论文关键词:超导体; 临界条件; 结构分析; 电磁储能; 比热;xrd衍射分析法 Keyword: superconductor; Critical condition; Structure analysis; Electromagnetic energy storage; XRD diffraction analysis 目录 第一章 绪论 6 第一节 超导体的基本属性 6 1.1 超导的零电阻现象 6 1.2 完全抗磁性 7 1.3、临界磁场 8 第二节 超导的发展历程 9 第三节 超导的应用及发展前景 10 第二章 实验方法与手段 12 第一节 实验样品CsNi2Se2的合成 12 第二节 铯镍硒(CsNi2Se2)的物性研究 14 2.2.1 结构分析 14 2.2.2 CsNi2Se2电性分析 16 第三章 实验总结与感想 (责任编辑:qin) |
