| 摘 要： | 本文提出了利用声光衍射来测量海水中悬浮沙浓度的方法.依据声光衍射理论和超声在悬浮液中传播特性,推导出声光衍射损耗系数之比与悬浮沙浓度的关系式,并利用He-Ne激光器,对浓度低于1kg/m3的高岭土海水悬浮液进行了实验.

| Abstract: | The new method of measuring sediment′s concentration in the seawater by the principle of acoustooptic was reported.Based on the principle of acoustooptic diffraction and ultrasonic propagation in the suspension sediment,the relationship between the diffraction loss coefficient and the sediment′s concentration was found.Kaolinite suspensions that concentration is less than 1kg/m3 were tested with He Ne laser. |

| Keywords: | Sediment′s concentration Acoustooptic diffraction |
