从数值和解析两方面研究了弦相连的三维单极子网络的宇宙学演化。我们发现，网络以一种自相似的方式进化。单极和反垄断会湮灭，在网络中造成越来越大的缺口，因此网络的典型规模随着时间的推移而成比例增长。简要讨论了模型参数的观测约束和网络可能的宇宙学含义。
The cosmological evolution of three-dimensional networks of monopoles connected by strings is studied both numerically and analytically. We find that the networks evolve in a self-similar fashion. Monopoles and antimonopoles annihilate, creating larger and larger gaps in the network, so that the typical scale of the network grows proportionally to time. Observational constraints on the parameters of the model and possible cosmological implications of networks are briefly discussed.
