摘　　要：本文研究了应用激光扫描技术获得Y-Ba-Cu-O体系超导层,用SEM和EDS观察和分析了它的微观结构和原子比。超导层是由多相组成的网状结构,非超层是棒状结构。超导层和非超导层中的原子比是不同的。实验和测定结果,确切地证明了试样在激光扫描下形成了超导层。The authors described in this paper the method to obain the superconductive layer of Y-Ba-Cu-O system by laser scanning, observed and analyzed its microstructure and atomic ratio with SEM and EDS.The microstructure of superconductive layer is a kind of network of many phases,which is different from non-superconductive layer of the pole shaped structure in the atomic ratio. It has been proved by experimental results that superconductive layer can be formed in a sample by layer scanning.
