The piezometric head is also measured from the same datum level. 测压水头亦应从同一基准面算起。
Chooses of the customers are diversified ,we can process high-pressure assembly, piezometric hose, PTFE hose, ultra-high pressure hose assembly,etc. 公司不仅可以加工高压液压软管总成，还可以加工测压软管、铁氟龙软管、超高压软管总成等，为广大客户提供了多样化的选择。
By analysis of quality and quantity, the abnormal reason are studied of partial old and new piezometric holes located in the Hua-An Sluice. 通过定性和定量分析，研究了华安闸坝部分老测压孔和部分新测压孔水位异常的成因。
There are two conditions in the data analysis of piezometric tube observation: confined seepage flow and unconfined seepage flow. (2)建立大坝有压渗流观测资料的统计分析模型。
This paper introduces the structure and the observation principle of piezometric tubes,and probes into several problem s in design,construction,and management. 介绍了测压管的构造和观测原理,对其设计、施工及管理中的一些问题进行了探讨,并详细分析了测压管滞后的原因,最后提出了一些建议。
On the basic of predecesser s study,the authors expound the reationship among depression cone radius and piezometric propagationg velocity are caculated in a electrical water source head. 在前人研究的基础上，作者详尽地推导了上部入渗补给为常量情况下的降落漏斗半径和水压力传递速度与时间的关系式，并对某电厂水源地进行了计算。
