The flume experiment with single spur dike is carried out . water surface profile and velocity field of flow in flume are measured by manometer tube and propeller current meter respectively 首先进行了单丁坝水槽实验,采用测压管和旋浆流速仪对实验水槽中水流的水位以及流速场进行了详细的测量。
Firstly , a computer samples the surface profile signal . secondly , the surface roughness is extracted though a digital filter , and then the surface roughness can be evaluated 该系统首先对表面信号进行采样,转换成数字信号后输入计算机,然后进行数字滤波分离出粗糙度信号,据此可以评定表面粗糙度。
