对于船舶及海洋平台等海洋浮式结构物，在其水动力试验过程中针对其横摇、纵摇运动数据进行分析，计算得出其固有运动周期及阻尼系数，进一步为船舶水动力试验的开展提供支持。(For floating structures such as ships and offshore platforms, the rolling and pitching motion data are analyzed during their hydrodynamic tests, and their inherent motion periods and damping coefficients are calculated to provide further support for the development of ship hydrodynamic tests.)
