摘要
本文从最大熵原理出发,研究了有极分子电介质的极化规律.结果表明,有极分子电介质的电极化强度与电场强度并非遵从严格的线性关系,只是当电场不很强时,电极化强度与电场强度近似成正比,而当电场强度非常大时,电极化强度将趋于定值.利用该原理同样可以研究无极分子电介质的极化问题.
Polarization of polar molecule dielectric is studied based on maximum entropy principle in this paper.The result shows that its electric polarization intensity is not proportional to the electric field intensity.Only when electric field isn＇t very strong,the electric polarization intensity is proportional to the electric field intensity.However,when electric field is very strong,the electric polarization intensity will tend to be constant.The polarization of non-polar molecule dielectric can also be studied based on this principle.
