摘要
本文利用我们所提出的键参数拓扑指数H与线性回归方法。得到了A-15超导体和Ba_2RECu_3O_(9-δ)氧化物超导体的临界温度与其组成元素的原子电荷—半径比之间的定量关系式.利用改进型的键参数拓扑指数′H,分析了超导体晶胞原子与次级晶胞原子间的相互作用对临界温度的影响.
A quantitative relationship between critical temperature of A-15 superconductors and single-phase Ba_2RECu_3O_(9-δ) superconductors and their component elemental atomic charge-radius ratio was obtained by using bonding parameter topological index and linear regressive method. The improved molecular topological indes 'H_(th) was advanced to analyse the effect of atomic interaction between cell and secondary cell on critical temperature Tc of superconductors.
