摘　　要：Datasonics声学探测系统的主要功能之一是实时探测水体中悬浮颗粒物浓度的时空分布。本文论述了该系统输出信号与悬浮物浓度的关系,分析了关系式中各项的意义,给出了Data-sonics系统悬浮物浓度的计算实例:并对声学系统参数的确定及其在计算中的应用进行了讨论。对于不同的声学系统,可根据各自的系统参数依此方法进行声学信号与悬浮物浓度的标定及计算。One of the function of Datasonics acoustic system is to measure the time-spa- ce distribution of concentration of suspended materials in water column in real time. The relationship between the output signals of the system and the concent- ration of suspended materials is described in this paper.The physical determinati- ons of terms in the formula are analysed. An example of calculating the concentration of suspended materials using the Datasonics system is given The method of deter- mination of the parameters in the acoustic system and their application to the ca- lculation are also discussed. Calibration of the relationship between the acoustic signals and the concentration and its calculation for different acoustic systems can be done using this method based on the parameter of these systems.
