本文利用温度Green函数和无规周相近似分析了准一维碳骨架分子中超导相和其它凝聚相出现的可能性和条件。结果表明,这类准一维有机聚合物(Cn聚合物群)由于Fermi面处发散的态密度而具有相当高的转变温度。这种转变温度与通常指数律不同而呈幂函数依赖关系:Tc-│g│n/(n-1)(g为有效相互作用强度)。在一定条件下,它们很有可能成为一类新的有希望的高温有机超导材料。The condensed phases of poly-Cn group are studied by means of the method of quantum field theory in statistical physics. It follows that the transition temperature for poly-Cn group obeys a power law because of the divergence of the density of states at the Fermi level. This class of materials has the possibility of exhibiting high temperature superconductivity.
