| 摘 要： | 本文将以YBa2Cu3O7-x的高温实验为基础,分析和讨论了氧对YBa2Cu3O7-x高温导电性的影响以及一维Cu—0链的导电作用。还报道了一种新现象,即在高温下,一旦氮气被换成氧气,YBa2Cu3O7-x就迅速地发生从半导体到金属的结构相变。

| Abstract: | Based on the result of the YBCO's experiments at high temperatures, this paper analysed and discussed the Influences of oxygen on the YBCO's conduction behavior at high temperature and the conductive actions of one dimensional Cu-O chains. We also reported a new phenomenon of YBCO in N2, i.e., once the N2 atmosphere is replaced by the O2 atmosphere at high temperature, a rapid stractural phase transition from semconductor to metal will occur. |
