| 摘要: |
| 本文对文献[l]中提出的层状势作了较为深入的研究，作出了相互作用强度U与ω间关系的曲线，U 与电子密度N0e间关系的曲线和U与铜氧层数l间的关系曲线。进而对层状势的微观机制—Cu-O层的有效哈密顿量进行了研究，得到了铜氧层的有效哈密顿量，讨论了空穴(附属费密子)凝聚成库柏对的条件。 |

| Abstract: |
| This article makes a deep study on layer potential developed in reference[l]. The curves that describe the relation between U and e1ectron density N0e，and the relation between Cu-O plane number 1 and U，are traced. Furthermore，this article studies the micromechanism of layer potential-effective Hamiltonian for Cu-O layer，Effective Hamiltonian for Cu-O layer is obtained. The condition for holes (slave-fermions) to be condensed to Cooper pairs is dicussed. |
