摘要: 根据铁基超导体晶体结构的不同分类，重点讨论了掺杂和加压下结构对超导电性的影响，总结了影响超导电性的局域结构因素及其理论和实践意义 According to the various classes of crystal structure of iron-based superconductors, the influence of structure on superconductivity is mainly discussed by doping or under pressure. The structural facts which influence the super- conductivity are summarized and the important significance in theory and practice is also discussed.
