摘要
隔声去耦覆盖层是一种重要的舰船水声材料与结构，敷设于潜艇艇体耐压壳外表面。大量研究结果表明，隔声去耦覆盖层在抑制艇体结构的振动、隔离潜艇内部各种噪声向艇外辐射等方面有重要的意义。就其作用机理、基体材料、声学结构、理论分析的研究现状进行了简单介绍，并通过对相关研究成果的分析，指出了其进一步研究的方向。
Isolating-sound and decoupling coating is a important underwater acoustic material and structure, and it is coated the outer surface of the submarine body which is used to support sound press. It is indicated by many research results that isolating-sound and decoupling coating not only restrains the vibration of the submarine structure but also isolates different noises from the inner of the submarine to diffuse to the outer of the submarine, and these factions have important significance. In the paper, the research state now is simply described in the function mechanism, the base material, the theory analysis and the acoustic structure. And it＇s research orientation foreground is pointed out by the pertinent research results analysis.
