混合磁性—介电材料的磁导率和介电常数的变化规律

The Varying Regularity of Magnetic Permeability and Dielectric Constant of Mixed Magnetic-Dielectric Materials

建立混合材料中的极化和磁化模型，引入等效退极化场和等效退磁化场的概念，推导了混合磁性—介电材料的性能参数（磁导率、介电常数）的变化规律，得到了理论与实验相吻合的结果。

The concepts of equivalent demagnetizing field and equivalent depolarizing field havebeen introduced,and a new formula for calculating the magnetic permeability and dielectricconstant of multiphase composites is derived.It has been found that the resuIts from the formulafit the experimental data very well.
