ANALYSIS PROCESSING METHOD USING IMPEDANCE SPECTRUM DATA, IMPEDANCE SPECTRUM DATA ANALYSIS PROCESSING SYSTEM, AND IMPEDANCE SPECTRAL ANALYSIS PROCESSING PROGRAM

This method for analysis processing by using measured impedance spectrum data includes: a step for determining whether to reset the maximum value and/or the minimum value of logarithmic relaxation time corresponding to a measured logarithmic frequency on the basis of the measured impedance spectrum data; a step for setting the number of equal-interval divisions within the range of the logarithmic relaxation time set in the determination step; and a step for analyzing parameters R∞, T, L, and R1 for the range of the set logarithmic relaxation time so as to satisfy a prescribed expression (A) by applying a regularized least-squares method.
