The refractive indices of some liquid and gas were measured by using one and two-side leaky mode method. Liquid or gas wag driped or filled between prism and substrate, so that these three layers media formed one or two sides leaky weveguide.

• 由单侧和双侧漏模法；测量了液体和气体的折射率；将液体或气体滴入或充入棱镜和衬底之间；使这三层介质组成单侧或双侧漏波导.
