摘　　要：超声波距离传感器是伴随科学技术不断发展的产物,通过反复的试验证实采用该设备可以用来测量坡面流水深,实验表明不同厚度的玻璃采用超声波水深测量系统测量时1.73%为平均误差,0.061%-0.096%之间是不同流量、坡度组合下坡面流测距的变异系数。可见超声波水深测量系统测量出来的精度可以满足室内侵蚀静床条件下坡面流水深测量的要求,值得被学者研究。The ultrasonic distance sensor is a product accompanied by the continuous development of science and technology.It has been confirmed through repeated experiments that the device can be used to measure the depth of water on the slope.The experiments show that 1.73%of glass with different thicknesses is measured with an average error.0.061%-0.096%is the coefficient of variation of downflow flow ranging for different combinations of flow and slope.It can be seen that the accuracy measured by the ultrasonic water depth measurement system can meet the requirements of water depth measurement on sloping surface under the condition of indoor erosion static bed,which is worthy of being studied by scholars.
