| 摘 要： | 文中尝试引进平均价电子数对掺杂Y1Ba2Cu3O7-δ(YBCO)体系超导电性进行分析。结果表明,掺杂YB-CO体系的平均价电子数Zv与转变温度Tc、临界电流密度Jc之间有较好高斯分布规律。因此,提出用平均价电子数作为提高掺杂YBCO体系超导电性的一个新依据。这对今后制备出具有更高Tc、Jc的掺杂YBCO超导氧化物有很好的指导意义。

| Abstract: | This paper introduced the average number of valence electrons and analysed the superconductivity of the doped YBCO system.Experiments revealed that the number of average valence electrons of the doping YBCO system between the critical current density and transition temperature has good Gaussian distribution regularity.It′s suggested that the number of average valence electrons can be used as a new good criterion for the experiment enhancing of superconductivity of the doping YBCO system.This is a good guidance for improving the superconductity of YBCO. |
