摘要：

The dynamics of a second-order phase transition during inflation, which is induced by time variation of space-time curvature, is studied as a natural mechanism to produce topological defects of typical grand unification scales such as cosmic strings or global textures. It is shown that their energy distribution is almost scale invariant with small- and large-scale cutoffs. Also discussed is how these cutoffs are given.
