            本文给出了掺气水流的运动、连续、质量平衡、动量及能量诸基本方程式.考虑了在运动方程式中出现的浓度紊动应力项的重要意义,应用普兰特紊流的混合长度理论,对二元明渠掺气均匀水流的流速分布公式进行了推导.在邻近渠底部分,紊动受底边界约束,混合长度与对底距离成正比,流速分布与通常均质紊流相似,为对数曲线.在邻近水面的部分,紊动自由,混合长度为常值,流速分布为直线的.二分布式均与已有的试验结果符合.文中还继续根据分布式给出了谢才系数依据水流倾角、雷诺数、断面平均掺气浓度及渠底掺气浓度而变的表示式.

            潮汐水流属于明渠非稳定流的一种类型,其计算工作量十分烦琐。本文试图在瞬态法的基础上,根据苦干潮汐河渠的实际资料,将瞬态法对河段和整个河渠的两重试算简化为一重试算,卽对河段简化为直接解算代数方程的求解,因而仅需对河渠进行試求。为解决潮汐河的水位和流量計算問題,本文先研讨了山河渠分割而得的各河段的水位和流量計算,並推导了在各种边界条件下的計算公式,然后具体地运用这些計算公式闡明了解次潮汐河渠水位、流量的計算方法,且将計算成果与实际观测资料进行了比較。
