摘　　要：基于联络分解变量的紫外／红外分离,提出杨-米尔斯理论真空的强耦合极限表现为一个经典场论意义下色空间的黑洞．基于此想法,证明在强耦合杨-米尔斯理论中存在对偶超导体解．在量子水平下,强耦合理论的非微扰真空可由磁荷的多粒子体系构成,而理论的经典平均给出对偶阿贝尔-黑格斯模型．该模型预言了与最近的格点模拟相一致的结果:理论真空位于第一类与第二类超导体边界．进一步通过求解对偶阿贝尔-黑格斯模型讨论了色电场的对偶迈斯纳效应．Based on the ultraviolet/infrared scale separation of the connection decomposition variables, we propose that at the classic level the strong-coupling limit of the Yang-Mills theory vacuum behaves as a black hole with regard to colors. With this idea, we prove that there exists a dual superconductor solution for the strongly-coupled Yang- Mills theory, whose vacuum is made up of a many-body system of magnetic charges at the quantum level. The classic average of the theory reproduce the dual Abelian-Higgs model. This model predicts a result which is consistent with recent lattice simulations. The vacuum of the SU（2） gluodynamics is at border between type- Ⅰ and type-Ⅱ. The dual Meissner effect of Chromo-electric field is discussed by solving the dual Abelian-Higgs model.
