As a differential pressure type flowmeter, the basic theory of the V-cone is Bernoulli's equation, which is similar to traditional DP flow sensors.

与传统差压式流量传感器相同，其基本原理建立在伯努利方程上；然而，其机械结构的设计则与传统差压式流量传感器大相径庭。

This paper tries to deduct rigorously the equation for the flow rate by using the Bernoulli equation,and to provide the expression of flow rate coefficient.

在孔板流量计中，流体流过孔板，孔板前后的流道面积收缩，其静压能转化为动能，从而出现压差，压差的大小反映流量的大小。

While the fluid flows up along relative close and wider rift system under overpressure , its nature is close to pressure conduit flow in fluid mechanics,which could be described by Bernoulli equation.

流体在相对封闭的较宽阔的断裂系统中受超压作用上侵流动时，其性质接近于流体力学中有压管流的流动情况，其动力学特征可以用柏努利方程进行描述。

Or as one who yokes broad-browed oxen that they may tread barley in a threshing-floor- and it is soon bruised small under the feet of the lowing cattle- even so did the horses of Achilles trample on the shields and bodies of the slain. The axle underneath and the railing that ran round the car were bespattered with clots of blood thrown up by the horses' hoofs, and from the tyres of the wheels; but the son of Peleus pressed on to win still further glory, and his hands were bedrabbled with gore.

像农人套起额面开阔的犍牛，踏踩着雪白的大麦，在一个铺压坚实的打谷场上，哞哞吼叫的壮牛，用蹄腿很快分辗出麦粒的皮壳――就像这样，拉着心胸豪壮的阿基琉斯，捷蹄的快马踢踏着死人和战盾，轮轴沾满飞溅的血点，马蹄和飞旋的轮缘压出四散的血污，喷洒在围绕车身的条杆。

有舱底水泵、压载水泵、消防水泵、日用淡水泵、日用海水泵、热水循环泵；还有兼作压载、消防、舱底水泵用的通用泵。

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.

二项式产能方程只能描述高速非达西渗流，对于低渗压裂气井，地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样，二项式产能方程已无法描述气井的生产状况，必须建立新的方程。

Die cutting: The cutting of paper or card with a die or steel rules bint into desired forms on a press to give cut--out or folds in printed material.

模切：用铜模或钢线屈成模型，在压机上压切纸张或纸板的印成品，使它具有要求的形状或摺痕。

Wei Daoshi feudal ethics of their city as if biotite pressure to Huang Fei, who asked not to another young woman when the pressure of the past.

封建礼教的卫道士们如黑云压城般向这位不愿再当皇妃的青年女子压了过去。
