摘要
根据临界水深理论和边界层理论，研究了Ｕ形（圆底形）长喉道测流槽的流量系数，推导了该测流槽的水深流量关系的计算公式，和国际标准给出的算例对比表明，本文提出的计算公式完全满足精度要求。
Based on theories of critical depth and boundary layer, this paper presents the discharge cofficient of long throated flume with U (circular bottom) shape. The formulation to evaluate relationship between flow depth and discharge is also deduced, whose accuracy satisfies the ISO demand perfectly.
