摘　　要：利用费米统计公式证明了微分铁电或铁磁回线可分解为一至两个高斯或洛仑兹线型之和 .对TGS ,BaTiO3 单晶 ,和硅钢片 ,锰锌铁氧体的测量证明理论与实验完全符合 .用微分回线代替回线来表征材料性质更具有实用和理论上的意义 .It has been proved that differential ferroelectric or ferromagnetism hysteresis loops may be regarded as the composition of two Gaussian or Lorentz profiles by means of the Fermi statistical equation.The theory is corresponding well to the results of experiments in measuring TGS,BaTiO 3 single crystal silicon steel and manganese-zinc ferrite.As a token of the characterof materials,it is the differential hysteresis loop,rather than the hysteresis loop,has much more meaning both in the theory and in applications.
