Kramers－Kronig变换对电化学体系的适用性

On the Validity of Kramers-Kronig Transform for the Electrochemical Systems

从复变函数的解析性质讨论了Ｋｒａｍｅｒｓ—Ｋｒｏｎｉｇ变换对电化学体系的阻纳的适用性．由于电化学体系并非总可视为线性．故Ｂｏｄｅ四条件不一定都能得到满足，文中提出检验电化学体系阻纳适用Ｋ－Ｋ变换所必须满足的三个必要充分条件，并讨论了各种不同的解析形式和等效电路对Ｋ－Ｋ关系的适用性．

The validity of Kramers--Kronig transform for the electrochemical systems has been discussed on the basis of the analytic properties of the immittance as a function of complex variable. As electrochemical systems canno always be regarded as linear, Bode's four requirements have to be reconsidered.Three necessary and sufficient conditions are proposed to test the clectrochemical systems to see whether K -- K transform is valid for them.
