本工作研究了超导体YBaCuO用不同的材料比例和掺微量杂质Mn和Co进行烧结的工艺。实验表明,掺Mn和Co等微量杂质后,超导体YBaCuO的零电阻的温度基本不变(91K),但掺Mn的YBaCuO在制备成结后有一些异常现象。在超导体材料YBaCuO的器件研制中,实验表明,锯、磨、钻等机械加工对YBaCuO的超导电性 This work studied the superconductor YBaCuO with different proportions of materials and doped with trace impurities Mn and Co sintering process. Experiments show that doped with Mn and Co and other trace impurities, the superconductor YBaCuO zero resistance temperature substantially unchanged (91K), but the Mn-doped YBaCuO after the formation of some unusual phenomenon. In the superconductor material YBaCuO device development, experiments show that sawing, grinding, drilling and other machining superconductivity YBaCuO
