3、ane of cuprate superconductor20 Dong Hang(Institute of applied physics and computational mathematics,Beijing,100094)Abstract: The existing theory about the cuprate superconductor bases on band theory, all neglects the position difference of Cu-O ions on plane, and assumes that the charge on ions are

4、 averagely distributed. Considering that the nature of conduction is the moving of electrons, carrier 25 means electron in this article. The charge opposite the carriers distributes on fixed ions, and the position difference of Cu-O ions slightly violates average electricity distribution, so the con

5、cept of hole is not suitable. It is proved that, near the optimal doping level, since the density of ions is relatively low, the violations can be treated as a perturbation, and the ion lattice can be seen as a combination of regular lattice and dipole lattice. Considering about that the character o
