The results of the simulation also show that it is not suitable to install bottom sill or bottom slope in the project which have side-inflow forebay for improving the flow pattern.

同時計算亦表明，對于閘站合建樞紐此類側向進水流動，底坎、底坡整流效果不大。

And the test data, the above factors taken into account based on the bottom of the sill or flow dissipation stilling basin shape optimization.

并結合試驗資料，在綜合考慮以上影響因素的基礎上，對跌坎型底流消能工消力池體型進行優化設計。

Sulfide further accumulates where depressions in the bottom of the sill interfere with the flow system and act as natural riffles.

巖床底上如有陷穴，就起到天然溜槽的作用，干擾了巖流體系，使硫化進一步堆積。
