| 摘 要： | 本文用激光拉曼光谱研究经热超高压处理的YBCO氧化物超导体材料的结构特征。光谱数据表明该工艺过程除了改善YBCO氧化物超导体的物理性能外还有利于YBCO微观构型中正交相的相结构更趋完整，晶格有序度的加强以及二维CuO2网络的形成，讨论了结构变化和超导电性的关系。

| Abstract: | Laser Raman spectra of YBCO oxide superconductor with hot ultrapressing and annealing treatment are reported.In addition to improving physical properties,the spectra data show that the processing can also perfect orthorhombic phase and enhance lattice on orientation trend as well as is good for formation of two dimension CuO 2 net.The relation between structure and the superconductivity has been discussed. |
