摘要：

We consider a model of grand unified cosmic strings coupled to the Weinberg-Salam model. When the string is superconducting we show that the electroweak symmetry is restored around the string out to a radius r0 is similar to gI/2piM(W)M(H). The presence of an ordinary cosmic string also leads to electroweak symmetry restoration, but in a much smaller region, r0 less-than-or-equal-to M(H)-1.
