冲刷破坏 meaning in English
failure due to scouring
Examples
- Destruction of erosion exists widespread and serious
冲刷破坏在平原灌区水闸中较普遍且严重。 - There are many reasons of causing destruction of erosion . apron do n ' t give full play to eliminating reminder of energy and adjusting velocity of flow in order to avoid or decrease erosion is one of them
冲刷破坏的原因很多，其中，海漫未能充分发挥其进一步消除余能、调整流速以减小或防止下游的冲刷作用，也是原因之一。 - The reason to creates this kind of destruction to be very many , the main of them is that the apron partially has not been able fully to display it to eliminate energy affect so causes the ditch bed to wash out , forms flushes the pit , leading to the apron , to guard against flushes the trough and both banks slope protection destruction , for a long time , disappear power design of plunge basin and layout have been focused on disappear power . but not to give the enough value on uses the sea to inundate the section to disappear power and adjust speed to reduced downriver washes out
水闸闸下冲刷破坏的部位绝大多数发生在消力池下的海漫和防冲槽处,造成这种破坏的原因很多,其中很大一部分是由于海漫部分未能充分发挥其消能作用而引起渠床冲刷,形成冲坑,导致海漫、防冲槽及两岸护坡的破坏。一直以来,人们把消能的研究重点放在消力池的消能设计及平面布置上,而对海漫段消能及调整流速功能研究甚少,至于对海漫加糙水流运动建立数学模型,在国内外还很少见相关的论文资料。 - The existing results about scour hole was summarized . experiments was made about the influence of aeration on scour , the dynamic pressure on the original riverbed and the scouring hole bottom , and the influence of aeration on the dynamic pressure and the velocity of submerged jet . scour was simulated by numerical model
在总结前人研究成果的基础上，试验研究了掺气对基岩冲刷破坏的影响；基岩冲刷过程中冲坑底部脉动压强随冲坑深度的增加而变化的特性；掺气对冲坑未形成前河床底部及基岩冲刷坑底部脉动压强的影响；掺气对射流轴线流速变化的影响等。 - The results showed that the accuracy and the repeatability for online concentration acquisition could not be assured with this approach even though the obtained electroconductivity curves were essentially consistent with those of hlozny ' s , because the electrode constant will be changed in the crystallization operation
但由于悬浮晶粒及其在强流体场作用下对测试电极产生的冲刷破坏作用，致使电极常数改变，影响测定结果的准确性和重现性，难于实现浓度的在线测定。
