The results indicate that orifice efficient water head is total water head and is not hydraulic head for uniform discharge along porous pipe. 结果表明，对沿途均匀泄流管道来说，其作用水头不能仅以压头为计算依据，而应以总水头为准。
The empirical equations for caculating the discharge of the sluiceway are suggested after the discharge characteristic regions and flow types are given. 在给出泄流特性分区及流态划分后，提出该种泄水道的泄流量计算公式。
