把方法基于回响,粘滞 0.2-2.0 kg/m3 的吸收沉积和玻璃祷告混浊的海水被测量。测量结果与用粒子尺寸分布技术的预言结果更一致而不是使用平均粒子半径技术,这被显示出。由预言的比较,用粒子的结果用平均粒子半径技术与那缩放分布技术,差异是 2.3-2.6 dB,这被观察为沉积的 1.0 kg/m3 的每 100 米在试验性的频率的范围以内的混浊的海水。粒子尺寸分布应该在预言被考虑,这被建议粘滞沿海的混浊的水里的吸收。
Based on reverberation method, the viscous absorptions of 0.2-2.0 kg/m3 sediment and glass bead turbid seawater were measured. It is shown that the measurement results were more consistent with the prediction results using particle size distributions techniques instead of using average particle radius techniques. By comparison of the prediction results using particle size distributions techniques with that using average particle radius techniques, it was observed that the discrepancy is 2.3-2.6 dB every 100 meters for 1.0 kg/m3 of sediment turbid seawater within the scope of experimental frequency. It was suggested that the particle size distributions should be considered in the predictions of viscous absorption in coastal turbid waters.
