研究了不同粗糙度的银镜对不同分子的表面拉曼增强效应，实验结果表明：在吸附分子与银镜之间同时存在物理增强和化学增强两种机制，物理增强与银镜衬底的表面粗糙度有关；化学增强则与吸附分子的化学性质有关，总的增强效果因分子而异．
The surface Raman enhancement effect of different roughness silver mirrors on different molecules was studied. The experimental results show that there are two physical strengthening and chemical strengthening mechanisms between the adsorbing molecules and the silver mirrors, physical strengthening and the surface of the silver mirror substrate Roughness; chemical enhancement is related to the chemical nature of the adsorbed molecules, the overall enhancement effect varies with the molecule.
