1)  cylinder measuring flume
柱形量水槽
1.
The cylinder measuring flume is a miniature discharge measuring equipment, which is formed by setting a removable post or canister for engendering critical state of flow here on the axes in the original prism channel.
柱形量水槽是直接在原有棱柱体渠道轴线上设置一个可移动的柱或筒,促使水流在该处形成临界水流状态来测流的小型量水设备,无需改变原有渠道断面结构,适合在对称的矩形、梯形、U形等断面渠道上安装使用。
2)  ribbed flutings
肋形柱槽
3)  parabolic thin-plate weir
抛物线形量水槽

机翼形量水槽是直接在原有或新建棱柱体渠道上,以渠道轴线为对称轴修建机翼柱形,促使水流在该处形成临界水流状态进行流量测量的量水设备,无需改变渠道断面结构,适合在对称的矩形、U形等断面渠道上安装使用。
3.
This paper research on the experiment of airfoil-shaped measuring flume in trapezoidal channel and educe the discharge formula in state of free flow in trapezoidal channel by the dimensional analysis.
本文对梯形渠道机翼形量水槽进行了试验研究,并应用量纲分析得到了梯形渠道机翼形量水槽在自由出流状态下的流量公式,根据量纲分析建立的流量公式满足量纲和谐性,简明实用,测流精度较高,量测流量的平均相对误差为0。
5)  trapezoidal weir
梯形槽口量水堰
6)  rectangular channel
矩形水槽
1.
Through experiments,the relations among the water depth(h),discharge(Q),canal grade(i),hydraulic head(H) in front of the sluice and the gate opening(e) in the rectangular channel are researched.
通过放水试验,研究矩形水槽内闸后水深h与流量Q、渠道纵坡i、闸前水头H、闸门开度e等物理量之间的关系。
补充资料:V形柱式支座
分子式:
CAS号:

性质:每两根支柱组成一组呈V字形结构,每组支柱与球形容器的赤道圈等距离相连,柱间无拉杆连接的一种球形容器柱式支座。其承受膨胀变形较好。并且由于支柱与壳体相切,相对赤道平面的垂线向内倾斜2°~3°,因而在连接处可产生一向心水平力,增加了基础的稳定性。
