摘要
本文利用超声波在含有气泡水流中传播特性，提出一种新型的水流掺气量测试方法，并进行了大量的试验研究．结果表明。本文所提超声接气量测量方法，具有结构简单，使用、维护方便，性能稳定等优点．是水工建筑物等工程野外观测及室内模型试验研究中，值得进一步研究和推广的一种方法．
Based on the behavior of ultrasonic propagation in water flow containing air bubbles, a new equipment for the measurement of concentration of entrained air in water flow is development. It has advantages in operation, installation, real time measurement and Dn line read out of concentration of entrained air, and thus can be an effcient equipment for field measurement and indoor model research in hydraulic engineering.
