| 摘 要： | 利用水下声信号在水表面引起横向微波振幅很小的条件，将普遍的流体力学方程线性化，推导出水表面一维模型的横向微波色散关系以及波的传播形式。结果表明：水表面横向微波具有波长短、传播速度小的特点，因而可以对入射到表面的激光束进行调制，为水下的声信号检测奠定了理论基础。

| Abstract: | On the condition of the underwater acoustic signal, the perturbed amplitude would be small, and then the general hydrodynamic equations may be linearized. On the basis of this approximation, the dispersion relation and the form of the water surface horizontal miniwave are obtained. The results show that the water surface horizontal miniwave has the characteristics of shorter wavelength and lower velocity, therefore it can modulate the light intensity of the incident laser beam on the water surface, which provides the theoretical basis for the detection of underwater signal. |
