在文献[1]中,我们讨论了声在海洋沉积物悬浮液中衰减测量的问题。本文由实验测量的数据,研究了低体积浓度范围内,在不同频率时,体积浓度的测量值和衰减系数测量值的相关关系,相应的回归直线。利用回归直线由衰减值估计体积浓度时,估计的标准误差。以及利用四种不同的悬浮液中声衰减理论,由衰减系数测量值估计体积浓度时,估计的标准误差。讨论了它们之间的差异。 In [1], we discuss the problem of sound attenuation measurements in marine sediment suspensions. In this paper, the experimental data measured the concentration range of low volume, at different frequencies, the measured value of the volume concentration and the attenuation coefficient measured value of the corresponding regression line. Estimated standard error when estimating volumetric concentration from regression values ​​using regression lines. And estimating the standard error of the volumetric concentration from the attenuation coefficient measurements using the four different sound attenuation theories in suspension. Discuss the differences between them.
