用微分时域谱方法，可以将陶瓷的介电、压电和热释电效应中来自铁电极化、异极电荷和同极电荷的贡献分开．对同一样品作介电谱和热释电谱测量，可以区分异极和同极电荷的分量；因为两者的热释电效应反号．
In dielectric, piezoelectric, and pyroelectric effects, the contributions of ferroelectricity, heteropolax charge, and homopolax charge can be studied sepaxately by using differential time domain spectroscopy method. For a same sample, by measuring the dielectric and pyroelectric spectra,the components of heteropolar and homopolar charges can be separated. In pyroelectric effect, the components of these charges have opposite signs.
