【摘要】 将HT模型和BLBL模型结合起来,通过对两个频率下超声波衰减系数测量,反演得到被测泥沙悬浊液中颗粒平均粒径。并在实验中通过对泥沙悬浊液在1MHz和2MHz频率下进行测量,证明用该模型及方法测量这类悬浊液的粒径大小是可行的。更多还原

【Abstract】 HT and BLBL models are used to calculate the particle size of suspended sediment in rivers based on the observation of the attenuation coefficients of ultrasonic under two different frequencies.The feasibility of using these models to determine the sediment size of suspended load is furture supported by experimental data.更多还原
