1) Dieshui
“跌水”
1.
The cause of Dieshui in Caowei River channel was studied in the light of geology and water dynamics.
在收集地理、地质及水文等资料并对其进行详细整理分析的基础上,利用多时相卫星数据和航片,在相应数字图像处理软件的支持下,对草尾河进行系统的遥感地质解译,并从地学和水动力学两方面研究了草尾河航道灵官嘴“跌水”形成的原因,预测了发展演化趋势,为草尾河的航道疏浚提供参考资料。
2) drop water
跌水
1.
Drop water is one kind of common channel system structures,it mustexist that the transition from supercritical flow to subcritical flow when water pass through the gap of drop water.
跌水是一种较为常见的渠系建筑物,当水流经过跌水口时必然产生缓流向急流的过渡。
2.
if we could use the drop water to gauge water accurately, it might not only reduce the loss of head caused by gauging facility of irrigation system, but also might save a lot of additional construction costs for gauging water and also reduce the project quantity, so it is one kind of economical and conv.
跌水为水利工程中一种较为常见的落差建筑物,特别在我国广大丘陵塬坡地区的渠道输水工程中采用的较为普遍。
3) Drop aeration
跌水曝气
1.
As a result,this paper recommends the integrated constructed terrace wetland because it can make good use of drop aeration,and the wetland covers less land and needs lower cost on running and managing than wastewater plant.
该工艺充分利用山体坡度和水体势能进行跌水曝气,不仅节约了耕地,还极大地节省了运行和管理费用。
4) drop-aeration
跌水曝气
5) waterfall aeration
跌水充氧
1.
In order to meet the technical requirements of smaller occupancy area,higher efficiency of nitrogen and phosphorus removal,easier maintenance and lower operation and construction cost in the treatment of rural sewage in the Taihu Lake valley,a full-scale experiment on use of the combined process of anaerobic/waterfall aeration contact oxidation/constructed wetland was carried out.
为了使太湖地区农村污水处理达到占地面积小、除磷脱氮效率高、管理简单、运行和建设费用低的目标,采用厌氧/跌水充氧接触氧化/人工湿地组合工艺进行了工程规模的试验研究。

补充资料：跌水
| 跌水 drop 使上游渠道或水域的水安全地自由跌落入下游渠道或水域的落差建筑物 。多用于落差集中处 ，也用于渠道的泄洪、排水和退水 。以砌石和混凝土建造者居多。单级跌水由5部分组成。①进口连接段，即上游渠道和控制堰口间的渐变段。②控制堰口，亦称控制缺口。它控制和调节上游水位和通过的流量，断面常呈梯形或矩形，可设或不设底槛，可安装或不安装闸门。渠道很宽时可采用多堰口。③跌水墙，即跌坎处的挡土墙，同控制堰口连结成整体。④消力池，位于跌坎之下，断面多为梯形或矩形，用于消除因落差产生的水流动能。⑤出口连接段，将水流平稳引至下游。落差在 5 米以上时 ，一般采用多级跌水 。多级跌水的结构与单级跌水相似。其中间各级的上级跌水消力池的末端，即下一级跌水的控制堰口。 |
