  1. Through the flume experimental research, the velocity distribution formulas for rectangular open channel have been found, including parabola form of velocity distribution on the vertical and power form of mean velocity distribution on the transverse direction ; meanwhile, the means of ascertaining correlative coefficient have been given in this paper

    摘要通過對明渠流速的水槽試驗研究，建立了矩形斷面明渠沿垂線流速的拋物線分佈公式和橫向平均流速的乘冪函數分佈公式，同時給出了相關系數的確定方法。
  2. The motion characteristics of the suspended particles were obtained by statistical analysis, including vertical concentration distribution, mean velocity profile, turbulent intensity, velocity correlation, and the probability density distribution of the velocity fluctuations. attempt has also been made to interpret the turbulent characteristics in terms of particle properties and turbulence structure

    對不同容重、不同粒徑的顆粒在不同水流條件下的垂線濃度分佈、平均速度和脈動強度分佈、相關函數及脈動速度的概率密度分佈等進行了全面系統的統計分析，得到的中文摘要主要成果如下：
  3. ( 2 ) before and after the frames are placed the velocity vertical distribution in the same cross - section are measured by adv. the results indicate that after the frames are placed the mean velocity and turbulent intensity near bed are reduced, and vertical distribution of turbulent intensity is more uniform

    （ 2 ）採用adv超聲流速儀對投放框架群前後同一斷面的垂線流速分佈測量表明：水槽投放四面體后，不但可以降低近底區的時均流速、紊動強度，而且均化了紊動強度的垂線分佈。
  4. ( 3 ) through dimension analysis, factors that affect the flow deceleration through frames are discussed. based on flume experiments, this study indicates the velocity near the bed decreases as the l / h increases, and the l / h decreases, the influence of frames height on the effect of velocity near the bed is not distinct ( 4 ) by 2 - d mathematical model, patterns of flow through frames are analyzed and the influence of different frame formations on the protection zone is researched, mean velocity in vertical decreases and protection zone enlarges as the l / h, b / b and a / h increases

    （ 3 ）通過因次分析，探討了四面體框架群減速率的影響因素，並進行了系列水槽試驗，得出：近底流速的減速率隨框架群相對長度l h的增加而增加，隨框架群相對間隔距離l h的增加而減小；框架群高度對近底流速的減速率影響不大，框架群高度的增加主要表現為減速區的增高。
