推广的Sullivan浸润相变模型(Ⅱ)——三重临界线

THE GENERALIZED SULLIVAN MODEL IN THE WETTING TRANSITION (Ⅱ)——THE TRICRITICAL LINE

对于推广的Sullivan模型,本文用改进的动力学方法讨论其能量条件线的拓扑性质不变性,建立了系统的展开方法,计算了参数空间中三重临界线的位置.计算结果在初级近似上与变分法的结论一致.

The improved dynamic approach is used to discuss the topologocally in- variant properties of the energy condition line for the generalized Sullivan model,and a systematic expansion method is advanced. By the new method the location of the tricritical line in parameter space is obtained, which is in agreement with those obtained by the approach of variation to the first order approximation.
