To certain viscosity experimental medium, the discharge coefficient of the great pitch pump is higher than the conventional pump, along with the obliquity of the pump barrel is increase(that is from the level to the vertical lay),the discharge coefficient of the well pump is increase, looked from the test result, the discharge coefficient of the great pitch pump is higher than the conventional pump, on this condition that low frequency of stroke, and it is more obvious on the small oblique angle condition.

对一定粘度的试验介质，大斜度抽油泵的流量系数高于常规抽油泵，随泵筒倾角的增加(即从水平放置到垂直放置)，抽油泵流量系数增大，从试验结果看，低冲次条件下，大斜度抽油泵流量系数高于常规泵，且小倾斜角状态较明显。

The purpose of a bridge is to filter traffic on a LAN- to keep local traffic local- yet allow connectivity to other pares of the LAN for traffic that is directed there.

网桥的作用是要过滤局域网上的流量――将本地的流量保持在本地-而有对要送往局域网的其他部分的流量建立连接。

Refering to the pricing of MBO, this thesis takes for that it's inconsequential to make net assets value per share as sole standard of pricing, and the standard of valuing must be traced back to free cash flow, and Free Cash Flow Valuation must be set up for pricing. And this thesis has brought EVA theory into MBO pricing to quantitating former contribution of management. Moreover, this thesis analyses controlling premium and marketability discount, and considers that we must develop the mechanism of market to improve the level of investors protection.

在对定价问题的探讨中，本文认为以每股净资产作为唯一定价标准不合理，衡量价值的标准应追溯到自由现金流量，应建立自由现金流量模型对管理层收购进行科学定价；本文还引入了EVA的理论量化管理层的历史贡献，以修正自由现金流量模型；同时本文认为定价时还要考虑控制权溢价和流动性折价，并且适当引入竞争，发挥市场机制，提高投资者保护水平。

This thesis establishes a comprehensive cash flow analysis model by reclassifying cash flow and makes a thorough revelation of the factors leading to changes in cash flow of listed corporations, thus providing more valuable informations for various users.

As the rate of flow of fresh air from the casing into an enclosure is substantially matched by the rate of flow of stale air from the enclosure, and heat is transferred between the two air flows by the heat exchanger (15), a total replacement of air in the enclosure at a relatively high rate can be sustained in an economically viable manner.

由于从壳体进入封闭体的新鲜空气的流量事实上和来自封闭体的旧空气流量相当，及由热交换器在两股空气流之间的传热，封闭体中全部空气的以相当高的流量更换能以一种经济可行的方式维持。

For the stability of the flow metering pumps, metering pump flow rate, as some big changes with pressure, you can set the exit of metering pump back-pressure valve, so that the output of metering pump flow rate stability, and then usually selected back-pressure valve The Reducing Valves pressure of the actual use of a metering pump metering pump pressure or slightly less than the use of pressure.

用于稳定计量泵的流量，如某些计量泵的流量随压力变化较大，可在计量泵的出口处设置背压阀，使计量泵的输出流量稳定，这时一般选择背压阀的压力为计量泵的实际使用压力或略小于计量泵的使用压力。

It also indicates that flow stability is determined by the throughput balance between single screw extruder and melt pump. Factors that influence flow stability and the approach to achieve it are discussed.

同时指出SP系统的流量稳定也取决于SP系统内部挤出机与熔体泵两者之间的流量匹配或平衡，讨论了影响平衡的因素和获得流量平衡的方法。

The flow rate of dynamic flow balancing valves has been set before leaving the factory,therefore adjustment is not needed in the field.

动态流量平衡阀的流量在出厂前根基系统流量进行定制，现场不需要进行任何调试。

After analyzing the performance anduncertainty of the DDPM vortex flowmeter in gas-liquid bubble flows, the vortexflowmeter-Venturi tube combinative method using the vortex flowmeter and the Venturi tube as measuring cells was put forward, the measurement model based on thevortex frequency and the Venturi differential pressure was established, and it showsthat the relative errors of this method for the mass flow measurement of bubble flowsare within±5%. Furthermore, the flowrate and volume void fraction of bubble flowswere obtained using a single DDPM vortex flowmeter through the relationshipbetween the frequency and amplitude of the circumferential DDPM signal, and resultsdemonstrate that the relative errors of the flowrate and volume void fraction of bubbleflows are within±5% and±10% respectively, which indicates the broad applicabilityof this method to large numbers of engineering fields.

通过分析管壁差压式涡街流量计在气液泡状流中的性能和不确定度，提出了以涡街流量计和文丘里管作为测量元件的&涡街—文丘里联合法&，建立了以涡街频率和文丘里差压为被测量的测量模型，该方法对气液泡状流质量流量的测量相对误差可达±5％；通过建立涡街周向管壁差压信号频率和幅度与被测流体的关系，使用单个涡街流量计实现了对气液泡状流流量和体积含气率的双参数测量，该方法对气液泡状流流量和体积含气率的测量相对误差分别为±5％和±10％，可以满足大量工业实际应用的要求。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
