%X 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.
