超声反射法测量悬浊液浓度分布的特性研究

在泥沙研究中，含沙量及其沿垂线分布的测量问题非常重要。目前基本上是采用传统的方法．费时费力，而且无法做到实时、连续测量。为了探索新的测试方法，本文报道利用超声反射法，根据声波在浑水中沿垂线传播时，不同深度、不同浓度泥抄颗粒对声波的散射信号不同这一原理，对泥沙浓度、深度及其粒径与散射强度的关系进行大量实验研究，以期能实现含沙量垂线分布的自动测试。

Study on utilizing ultrasonic for measurement of sediment concentration distribution

In the course of sedimentation research, the measurement of sediment concentration and its distribution is very important. At present, most traditional methods are arduous and cannot measure the sediment timely and successively. In order to seek the new measurement method, the paper reports utilizing ultrasonic measurement. When ultrasonic wave spreads along the depth in aqueous suspensions, the scatter intensity of sediment particles changes the depth and sediment concentration. Based on this principle, we experimented abundantly with the scatter intensity versus sediment concentration, the depth in suspensions and sediment diameter for the aims to realize automatic measurement in vertical distribution of sediment concentraion.
