摘　　要：从能够产生表面增强拉曼散射 (SERS)效应的典型金属银出发 ,讨论其在光频段的介电函数及与此介电函数相关的表面等离子体共振现象 ,进而用表面等离子体共振理论讨论SERS效应的电磁增强机理 .Silver is the typical metal that can lead to the surface enhanced Raman scattering(SERS) effect. In this paper, the dielectric function of silver is discussed. Furthermore, the surface plasma resonance (SPR) effect, which is concerned with the dielectric function intimately, is studied. The electromagnetic enhancing theory of SERS-SPR is discussed also.
