摘要:
金兹堡判据是判定平均场理论有效性的重要准则。本文从一道典型的高分子物理课程课后习题出发,通过求解过程总结在平均场理论框架下如何构造金兹堡判据,并将该思路推广到不对称两组分高分子共混物体系以及高分子溶液体系。
Abstract:
Ginzburg criterion is an important tool for determination of the validity of the mean-field theory. In this paper we start from solving an interesting problem on the Ginzburg criterion of symmetric two-component polymer blends presented in Polymer Physics, the textbook written by M. Rubinstein and R. H. Colby. A general strategy to construct the Ginzburg criterion for polymer blends and polymer solutions is summarized. The strategy is then applied to the asymmetric two-component polymer blends and polymer solutions.
