摘要: 本文提出一种用Kramers-Kronig(K-K)转换来检验阻抗数据可靠性的方法。该方法先将实验阻抗谱对具有明确物理意义的阻抗表达或进行曲线拟合,然后将拟台结果外推,从而可在从零到无穷大的整个频率范围内计算K-K积分,避免了积分计算的误差,提高了该方法的准确度。本文还讨论了对具有三个时间常数的阻抗谱的曲线拟合同题。

Abstract：A method used to check the reliability of impedance data by Kramers-Kronig transforms has been developed. The procedure consists of first,to fit experimental impedance data to the impedance expressions having true physical meaning and then,to extrapolate the fitting results to whole frequency range. In this way some errors in integral calculation can be avoided and the validity of the method can be improved. A fitting program which deals with the impedance spectra with three time constants has been proposed.
