摘 要: 证明了铜氧面上离子晶格可以看作是规则离子晶格和电偶极子晶格的组合,规则离子晶格与载流子维持电荷平衡,电偶极子晶格则来源于对离子电荷均匀分布的偏离。在假定电偶极子晶格对高温超导起主导作用的基础上,对高温超导的配对机制、载流子浓度与超导临界温度的铃型曲线、d波对称及正常态电阻率随温度的线性变化做了简要的解释。
关 键 词: 超导物理学;高温超导;电偶极子;相图;d波对称;超导正常态

Abstract: It is proved that, the ion lattice on CuO2 plane can be seen as a combination of regular lattice and dipole lattice. Regular lattice and carriers keep the balance of electron, while dipole lattice is from the violations of average electricity distribution. Considering that the character of cuprate superconductor is mainly dominated by the dipole lattice, the pairing mechanism, carrier concentration and the bell-shaped curbe, the d-wave symmetry and the linear temperature dependence of normal state resistivity are tersely interpreted.
Key words: superconductivity physics; high temperature superconductor; electricity dipole; phase diagram; d-wave symmetry; normal state of super conductor
