摘　　要：使用信息论中的最大信息熵原理,研究了非极性电介质在电场中的极化规律.发现当非极性电介质处于不很强的电场中时,电极化强度与电场强度成正比;而当它处于非常强的电场中时,电极化强度与电场强度不再成正比,而呈现较复杂的非线性关系.Polarization law of non-polar dielectrics in electric field is studied by use of information theory＇s maximum entropy principle. Results indicate that when the electric field strength isn＇t very strong, the electric polarization intensity is proportional to the electric field strength. However, when the electric field strength is very proportional relationship doesn＇t exist, and there is a complex non-linear relationship between the polarization intensity and the electric field strength. strong, electric
