1) drawdown of piezometric level
水位压降
2) confined water level declined
承压水位下降
3) ARB
降压地位
1.
Evaluation of ARB in Anithypertersive Therapy;
从LIFE和VALUE试验看ARB的降压地位
4) gravity pressure drop
重位压降
1.
Theoretical analysis shows that the effect of the frictional pressure drop on flow measurement can be reduced with a symmetrical structure;the effect of the frictional resistance can be eliminated by measuring the gravity pressure drop which is vertical to the flow direction in the slot segment.
理论分析表明,狭缝文丘里管利用对称结构可以减小或消除摩阻压降的影响,中间狭缝处垂直于水平流向的重位压降的测量同样避免了沿程摩擦阻力的影响。
5) drawdown
[英]['drɔ:daun] [美]['drɔ,daʊn]
水位骤降
1.
Stability analyses of slope under reservoir water level drawdown;
库水位骤降对边坡稳定性的影响
6) 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。
