Abstract: From the causal law of physical experimental facts,without concrete microscopic physical model, this paper discusses the physical mechanism and theoretical derivation of the Kramers-Kronig relationship based on Fourier transform,dispersion theory,and residue theorem.

Key words: Kramers-Kronig relationship, Fourier transform, linear response function, causality
