构造了纯量子色动力学（QCD）中具有内禀质量尺度参数和零自旋的正则定态轴对称解。有一类特殊的解可以看作是静态色单极子与动态非对角胶子的相互作用系统。我们表明，这种经典的解决方案描述真空的反胶子对凝聚体是稳定的量子胶子波动在每个时空点的最小附近。这有力地支持了基于QCD真空作为对偶超导体的夸克和色禁闭机制，并提供了真空结构的微观描述。
We construct regular stationary axially-symmetric solutions with intrinsic mass scale parameter and zero spin in a pure quantum chromodynamics (QCD). There is a special class of solutions which can be treated as a system of static colored monopoles interacting to dynamical off-diagonal gluons. We show that such classical solutions describe vacuum monopole-antimonopole pair condensate which is stable against quantum gluon fluctuations in the smallest vicinity of each space-time point. This strongly supports the mechanism of quark and color confinement based on QCD vacuum as a dual superconductor and provides microscopic description of the vacuum structure.
