我们考虑乌卡型过程对致密双味夸克物质的几个自旋一色超导相的体积粘度的贡献。在所谓的横向相中，被认为在渐进密度下在能量上是有利的，无间隙准粒子模式的存在阻止了自旋一色超导性对体积粘度有很大的影响。当所有模式都有间隙时，对于一种特定的颜色自旋锁定相，对粘度的影响可能相当大，这可能具有重要的唯象意义。
We consider the contribution of the Urca-type processes to the bulk viscosity of several spin-one color-superconducting phases of dense two-flavor quark matter. In the so-called transverse phases which are suggested to be energetically favorable at asymptotic densities, the presence of ungapped quasiparticle modes prevents that spin-one color superconductivity has a large effect on the bulk viscosity. When all modes are gapped, as for one particular color-spin-locked phase, the effect on the viscosity can be quite large, which may have important phenomenological implications.
