我们证明了两个Higgs二重态模型的参数空间存在一个约束，这个约束来自于稳定的涡域壁系统的存在。约束是相当普遍的意义上说，它只取决于两个组合的拉格朗日参数，并在树的水平，不依赖于如何费米子耦合到两个希格斯场。得到了畴壁涡旋系统场位形的数值解，为进一步定量研究涉及这类拓扑天体的宇宙学提供了基础。
We show that there is a constraint on the parameter space of two Higgs doublet models that comes from the existence of the stable vortex-domain wall systems. The constraint is quite universal in the sense that it depends on only two combinations of Lagrangian parameters and, at tree level, does not depend on how fermions couple to two Higgs fields. Numerical solutions of field configurations of domain wall-vortex system are obtained, which provide a basis for further quantitative study of cosmology which involve such topological objects.
