中文摘要：

YBa2Cu3O7-x（YBCO）超导涂层为导体的第二代高温超导带材由于其优异的本征性能，吸引着人们不断探索和研究其实用成材技术。现在，近千米长带的研制成功，使其已经或即将应用于电缆、马达和其他电力器件。为了更好地使YBCO涂层导体能够在高温高磁场下应用，最近在YBCO中引入钉扎中心以提高它的电磁性能的研究是一个热点。综述了近年来二代超导带材的发展状况，并对目前高温超导体中提高电学性能的研究做了较为系统的介绍。

英文摘要：

Owing to the high performance, the second generation （2G） high temperature superconducting tapes based on yttrium barium copper oxide had attracted much attention of worldwide researchers to develop the processing techniques for application. Now, hundreds of meters of high-temperature superconducting wire were manufactured for demonstrations of transmission cables, motors and other electrical power components. An overview of current research and development in the area of the second generation HTS tapes was presented.
