  • self : n （pl selves ）1 自己；自身；本身；【哲學】自我；我。2 本性；本質。3 私利；私心，私慾。4 〈俗〉...
  • cleaning : n 1 清潔法；掃除；清洗，洗滌；（種子的）清選。2 〈常 pl 〉（牛、羊等的）胞衣。3 【林業】除伐。4 ...
  • velocity : n. 1. 迅速；快速。2. 速度，速率。3. 周轉率。
  1. And the relation between these velocity was analyzed at last. this is the conclusion : ( 1 ) the distribution of the velocity and concentration are get in the open channel flow and as the sewage flow is gravity flow, the equations is fit for this too. ( 2 ) generally speaking, the self - cleaning velocity should be the starting velocity, and it could fit for the self - cleaning target in limited sense theoretically, but when facing some higher requirement, it is not large enough

    最後結合污水流動的最小設計流速與顆粒起動流速、臨界不淤流速的關系進行了分析，結論如下: （ 1 ）文中所得出的速度分佈與濃度分佈是在明渠兩相流動情況下推得的，由於污水管道流動多為重力流，是明渠流中的一種，所以文中的分析在認識污水流動特性方面具有一定的參考價值。
