摘要：

Molecular dynamics calculations are presented for a 3d system with a 2d order parameter (x, y). A local potential (described by an 8 order polynomial in x and y), is proposed, which leads to a sequence of three phases. Transition temperatures, polarizations, and dynamical structure factors are calculated and discussed. © 1991, Taylor & Francis Group, LLC. All rights reserved.
