Abstract
简述湍流仪国内外发展现状及剪切探头测量原理，据潜标湍流仪观测数据分析影响湍流仪测量结果的振动因素，探讨减少噪声污染方法。针对由系缆传递振动造成的噪声提出应用低温水性阻尼材料减震方法，减振实验数据分析结果表明，增加阻尼材料可有效降低振动对测量精度影响。
The submersible buoy with turbulence instrument is an effective and a long-term observation platform of the turbulence in deep sea and plays an important role in marine scientific research.The current development of turbulence instruments at home and abroad and shear probe measurement principle were briefly introduced.According to the measurement data by turbulence instruments in submersible buoys,the factors affecting the measurement results of turbulence instruments were analyzed.The methods to reduce noise pollution were discussed.Aiming at the reduction of noise caused by the vibration of cable transmission,the application of low temperature water damping material was proposed.The experimental data indicate that adding damping material can effectively reduce the influence of vibration on the measurement accuracy.
