文章针对小水线面双体船水下片体结构的声辐射特征，建立了近水面双柱壳的耦合声散射模型，通过对双片体结构与水面间耦合散射声场的数值计算，分析了双片体结构参数和水面镜面效应对散射声场的影响规律，提出了相应的噪声控制建议。

In order to study the radiated sound characters of SWATH (small waterplane-area twin-hull ship), the coupled scattering model of underwater twin-cylinder structure near the surface is developed, and the far field sound pressure excited by external force from machinery is solved by using numerical method. As an example, the effect of sound scattering by structure and free surface of a typical SWATH is analyzed, and the main conclusions and control methods are also presented.
