摘　　要：通过分析电流、电阻产生的原因和机理， 提出只有处于特殊结构中的电子对才可能成为超导体。根据量子化学计算结果推测， 氮杂十八轮烯衍生物的金属复合物可能会成为超导结构基元。According to BCS theory of the superconducting, the electron pair is essential for superconducting. As everyone knows, there are all over the electron pairs in the covalent bond. However, true to type covalent compound is an insulator, for example, diamond and overwhelming majority organic compounds as well. In this study,we proposed that the weak covalent electron pair in the special structure may be superconducting. The metallic atom or the ion that is in the center of big cycle conjugate system, as aza octodeca annulene (AOA), may be a superconductor. There must be an inverse magnetic induction in AOA acted by another magnetic field, that is Meissner effect. AOA Metallic complex may have a high Tc and a large I c.
