推广的Sullivan浸润相变模型(Ⅰ)——Sullivan线附近

THE GENERALIZED SULLIVAN MODEL IN THE WETTING TRANSITION(Ⅰ)——CLOSE TO THE SULLIVAN'S LINE

文章简要介绍了浸润相变中的推广的Sullivan模型,分析了以往的动力学方法和变分法所得结论的分歧。在此基础上,本文改进了以往的动力学方法,纠正了其中过于粗糙之处,重新讨论了Sullivan线附近浸润相变的级,得到与变分法一致的结论。与变分法相比,本文的优点是可以推广到远离Sullivan线的情况。

A breaf view on the generalized Sullivan model in the wetting transition is proposed. The difference in conclusion between the previous dynamic app- roach and that of variation is discussed. On this basis, the order of the wet- ting transition is reexamined when the values of parameters are close to the Sullivan's line. Compared with the approach of variation, the advantage of the new method is that the generalization is possible to the situation far from the Sullivan's line.
