根据ＳＥＲＳ天线共振子模型理论计算了Ａｇ，Ｃｕ和Ａｕ三种金属的ＳＥＲＳ增强因子．结果表明Ａｇ在可见光和近红外光区域的增强因子为１０４～１０５，Ｃｕ和Ａｕ在可见光范围内的增强因子较小，而在近红外光区域的增强因子可达１０５左右．这一结果同实验结果相符．
The SERS enhancement factors of three metals Ag, Cu and Au were calculated according to SERS antenna resonance model theory. The results show that the enhancement factor of Ag in the visible and near-infrared region is 104-105. The enhancement factor of Cu and Au in the visible range is small, while the enhancement factor in the near-infrared region is about 105. This result is consistent with the experimental results.
