万忠墓摘要：Light interaction with metal nanostructures expos exciting phenomena such as strong amplification and localization of electromagnetic fields. In surface-enhanced Raman spectroscopy (SERS), the strong signal amplification is attributed to two fundamental mechanisms, electromagnetic and chemical enhancement (EM and CM, respectively). While the EM mechanism is accepted as the main responsible for signal amplification, a long-standing controversy on the CM mechanism's role still 丝的形近字

However, it is also possible to induce similar spectral variations by changing the relative orientation between the electric field and molecule or when a high electric 床头柜一般多宽
