Because the flow meter orifice pressure by correspondence before the impact of heavy flow, if required flow accuracy of 10%, the valve must be over before the straight section 10d, and this works in practice extremely difficult to protect.

由于孔板流量计的流量压差对应关系受到前流态影响极重，如果要求流量精度达到10%，则必须阀前有10d以上的直管段，而这一点工程实际中极难保障。

This probe suits the measurement of micro gas flow,which conforms with the theory of the differential\|pressure orifice flow meter,and it is designed light and handy and used conveniently.

该探头适用微流量气体流量的测量，采用了差压式孔板流量计的原理，设计轻巧，使用方便，能够进行远距离无失真传输，方便了现场测试。

Orifice Meter - pilot valve - main valve principle.

孔板流量计——导阀——主阀原理。

The study on the characteristics of standard orifice flow meter in an air-lift pump was carried out by measuring the flow rate of water, a solution simulating high-level-liquid-waste and 30% trialkylphosphine oxide-kerosene solution.

探讨了气提泵输送水，模拟料液，30%三烷基氧膦-煤油溶液时标准孔板流量计两端压降特征。

In this paper,the principle for the orifice flow-meter to measure the hydraulic turbine wicket gate leakage was introduced.

本文介绍了用标准节流孔板流量计进行水轮机导叶漏水量测量的基本原理，结合实例介绍了计算方法并进行了误差分析。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
