Flow field calibration error will effect the uncertainty of the experimental data through data reduction process.
风洞流场校测误差通过试验数据处理而影响试验数据的不确定度。
Therefore, to assure the quality of the experimental data, it is important to improve the flow field calibration precision.
本文通过两相流理论分析和水力学试验验证证实：室内排水立管管壁粗糙度的减小，不仅不能加大其临界流量，反而会减小其临界流量。
It has been verified in this paper, by theoretical analysis with two-phase fluid mechanics and hydraulic tests, that decreasing surface roughness in a wade stack can not increase critical discharge.
