摘　　要：对两种含沙量(8．28千克／米^3和31．56千克／米^3)的模拟黄河水进行了在不同频率(3．2-20千赫)下的声衰减测量。结果表明：声衰减系数与频率之间基本上成线性关系，其斜率与含沙量有关。Sound attenuation measurement has been conducted for two kinds of simulated water of the Yellow River, the sand contents of which are 8. 28 kg/m3 and 31.56kg/m3 respectively, at different frequencies in the range of 3. 2 to 20 kHz. The results show that the attenuation coefficient varies approximately linearly with frequency, and the slope of the lines depends upon the sand content.
