1) lowering position
下降位置
2) Descent device
下降装置
3) drawdown
[英]['drɔ:daun] [美]['drɔ,daʊn]
水位下降
1.
Research on unsteady seepage problem of bank slope due to drawdown of reservoir water level;
库水位下降时的岸坡非稳定渗流问题研究
2.
The calculation shows that the safety factor declines with the drawdown of the water level under the drainage condition.
计算结果表明,当土体设置为排水条件时,在库水水位下降过程中,安全系数随水位的下降逐渐减小,但当水位下降了20 m以后,由于孔隙水压力给滑面提供了竖直方向的作用力,随着水位的继续下降安全系数反而略有上升。
4) descending spacing
下降限位
1.
It is brought forward how to solve the vertical ship lift with no descending spacing at Lushui Water Conservancy Project by means of a set of high-power alarm circuit and wireless remote control system.
提出了一套由大功率报警器电路和无线遥控系统来解决陆水枢纽垂直升船机无下降限位的问题。
5) water lowering
水位下降
1.
Owing to the overexploitation for groundwater thus leading the water lowering of groundwater, the formation and enlargement of the cone of depression, and the ground subsidence, such being the case, the geologic hazard will easily occur at any time.
因过量开采地下水而引起地下水水位下降，降落漏斗形成并扩大，同时引发地面沉降，造成地质灾害发生。
6) water level descending
水位下降
1.
Some problems, such as water level descending and water quality worsening caused by over-exploration of underground water analyzed.
介绍了山东省冠县的水文地质条件和地下水资源开发利用现状，分析了由于过量开采浅层地下水而引发的水位下降及水质恶化等问题，提出了合理开发利用地下水的建议。
