在水深1.0米,具有平坦海底的区域作了时域分离简正波的模拟实验,得到了1、2、3号简正波。由分离出的简正波相对幅度计算了海底反射损失因子Q。所得实验数据与理论计算结果符合甚好。计算所得Q值与由底质采样所得Q值基本一致。
At a depth of 1.0 m, a region with a flat seafloor was simulated by a time-domain simplified normalized wave, and a simple normal wave was obtained. The seafloor reflection loss factor Q is calculated from the relative amplitude of the separated normal wave. The experimental data obtained are in good agreement with the theoretical calculation. The calculated Q value is basically the same as the Q value obtained from the sediment sampling.
