摘　　要：简要叙述了超导电性基本概念和发展历程,介绍了近期Fe-基超导体及相关材料的结构与物性研究的进展,着重讨论了新型122体系Fe-基超导体的物理性能和微观结构特征。最后对当前超导体在电力能源、交通和通信领域的应用进行了简单论述。超导电性的研究已经有一百多年的历史,至今仍然是科学界的热点研究领域。可以预期,超导材料和器件将对未来社会文明和科学技术的发展产生较大的影响。The basic concepts and the development process of superconductivity was briefly described, the recent iron based superconductor and related materials structure and research progress were introduced,and the physical proper- ties and microstructure characteristics of 122 type iron based superconductor was emphatically discussed. At last,the current application of superconductor in power energy, transportation and communication field was discussed in this paper. The study of superconductivity had been a history of more than one hundred years, and it is still a hot research field in the world. It is expected that superconducting materials and devices will have a greater impact on the devel- opment of social civilization and science and technology in the future.
