我们发现，标准的180°区域理论不能一致地解释区域的一组重要性质。此外，标准的180°区域理论给出的偏振分布是一个闭合区域，这与实验结果似乎不一致。我们认为，理论中高相对介电常数的必要性表明了自由电荷电屏蔽的存在。提出了对标准理论的修正。
We show that the standard 180° domain theory cannot consistently explain a set of important properties of domains. Furthermore, the distribution of polarization given by the standard 180° domain theory is a closure domain, which appears to disagree with experimental results. We suggest that the necessity of a high relative permittivity in the theory indicates the existence of electrical screening by free charges. A revision of the standard theory is proposed.
