用时域和频域介电谱方法可以将晶界层陶瓷中晶粒、内边界层和阻挡层三种不同机构对外加电场的响应讯号分开。从而得出每种机构对样品的总电阻或总电抗的贡献。观察到极化子跳跃导电的弛豫效应，它使样品的阻抗呈现电感性。比较了掺杂氧化锌、钛酸锶和钛酸钡三种典型陶瓷的晶界层的异同。 Using the time-domain and frequency-domain dielectric spectroscopy methods, the response signals of the applied electric field can be separated from the three different mechanisms of the grain, the inner boundary layer and the barrier layer in the grain boundary layer ceramic. This gives the contribution of each mechanism to the total resistance or total reactance of the sample. The relaxation effect of polaron hopping conductivity was observed, which made the impedance of the sample appear inductive. The similarities and differences of the grain boundary layers of three typical ceramics doped with zinc oxide, strontium titanate and barium titanate were compared.
