摘要：

The time evolution of the three-dimensional critical Ising model relaxing from a non-equilibrium initial state is studied by means of Monte Carlo simulation. We observe the characteristic initial increase of the (spatially) averaged magnetization predicted by Janssen et al. The exponent theta' that governs the initial behaviour is determined, and the dependence of the long-time linear decay on the initial magnetization, m0, is analysed. Our simulation corroborates earlier results derived from continuum models.
