摘要：
铁电性质的宏观建模通常是指朗道-金兹伯格-德文希尔理论。本文质疑这一术语的意义，讨论三位作者对什么是理论的贡献。分析了每种贡献的局限性。在正文中，以及在补充材料中更大程度上，朗道理论是从一个不寻常的角度提出的，从自发对称性破缺的简单力学模型开始，到伊辛模型结束。介绍的目的是强调与上述三位作者相关的宏观建模的近似特征的定性突破。
英文摘要：
Macroscopic modelling of ferroelectric properties refers usually to Landau-Ginzburg-Devonshire theory. This paper questions the meaningfulness of this term, discussing contributions of the three authors to what is supposed to be a theory. The limitations of every contribution are analyzed. In the main text and, to more extent in the Supplementary Material, the Landau theory is presented from an unusual perspective starting from simple mechanical models of spontaneous symmetry breaking and finishing by the Ising model. The aim of the presentation is to emphasize along with the qualitative breakthroughs the approximate character of macroscopic modelling associated with the above three authors.
