摘　　要：从物理实验事实的因果律出发,脱离具体的微观物理模型,基于傅里叶变换、色散理论和留数定理,详细地论述了Kramers-Kronig关系的物理机制和理论推导.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.

关 键 词：K-K关系 傅里叶变换 线性响应函数 因果律
