摘要：

We report results from a simulated annealing study of a coarse-grained model for block copolymers. For sufficiently slow cooling rate, the system develops a well-defined lamellar structure by avoiding the formation of defects. We show that the strong segregation limit of the model is computationally accessible when the interface thickness is small enough.
