| 摘 要： | 用固相反应法制备123相YBa2-xSrxCu3O7-δ(YBCO)和掺Sr的YBa2-xSrxCu3O7-δ系列超导样品．利用四端引线电阻法测量样品的电阻温度曲线，得到Sr元素替代Ba位时超导转变温度Tc降低且Tc随掺杂量单调变化，从实验上验证了CuO2面的耦合可能是维持高温超导电性的一个重要条件．

| Abstract: | The superconductor samples YBCO (123 phase) and series YBaSrCuO of Sr doping have been prepared by the solid state reaction method. By a four base line resistance method,the authors can find that if Barium in YBaCuO superconductor was partly substituted by Sr,the samples' Tc will go down with the content of Sr in them. It justified that the coupling of CuO2 maybe an important factor of the high-Tc Superconducting capability. |
