摘要
最大熵原理是自然界的一个基本原理,在很多领域得到了广泛应用。使用最大熵原理,研究了二维有极分子电介质在电场中的电极化规律。结果发现,当电场强度不大时,电极化强度与电场强度成正比关系;但当电场强度很大时,电极化强度与场强的线性关系不再成立,而呈现较复杂的非线性关系。
The maximum entropy principle is a basic principle in nature, and it has been widely used in vari- ous fields. The maximum entropy principle is used to study polarization of two-dimensional dielectric of polar mole- cules. Result shows that when electric field strength isn＇ t very strong, the electric polarization intensity is propor- tional to electric field strength. However, when electric field strength is very strong, linear relationship between the electric polarization intensity and the electric field strength doesn＇t exist, and in this case there is a complex nonlinear relationship between them.
