英文摘要：

Noble metals nanostructures are wildly used in detection of trace chemicals based on the surface enhanced Raman scattering. The controllable fabrication of Ag nanorod arrays by oblique angle deposition and their application in detection of trace chemicals were introduced, and the semi-quantitative and quantitative analysis of trace chemicals were established by principal component analysis and partial least squared regression methods.
